I wanted to build flight controller from arduino. I almost gave up when I found these videos. It helps me a lot. Thank you

[@kckoellein]

Almost finished with my build, Joop! Thank-you for creating this project! I'm looking forward to digging into the code as a first SERIOUS programming project.

[@crazycampers5466]

@kc koellein, could you please help me out with the connections of the Ardunio UNO and the other circuits? For one, I just can't understand how to take a common ground for the ECS terminals(the three-pin section)

[@aakaarjaiswal5392]

@@crazycampers5466 I am in the process of building the drone and I am now facing the same problem. I designed my own frame and I am using solderable PCB for the power distribution board. One solution is to use header pins and connect all of them together and one of these pins goes to the ground pin in arduino

Hi i have a question about power Vin and A0 , if the batery is 3s = 11.1 Volts ..... The resistances is a divisor voltaje right? Vin= (11.1*1.5)/1.5+1 = 6.66volts and Volt Ao =4.44Volts..... but the power in arduino must be 7Volts---12 volts and Vin is 6.66Volts

[@silentehacker00]

+Carlos tercero no look well at the schematic vin receive 11.1 v not 6.66 loOk the wires. A0 receive 6.66 but i think it not safe for the board, because a0 must not recevie voltage higher than 5 v

[@nombreapellido5125]

+jones rayan OOoo its true... thnaks you very much for correct me , I suppose that A0 must have a regulator or something...

[@nombreapellido5125]

+jones rayan Its posible change de resistance R3.... if R3 is 820ohm ----> Vin=11.1(820)/1820 =5.00109Volts... The analog inputs have a diode but this diode can destroy if the voltaje is higher for a long period of time...

Hardware wise, this setup is frightfully mature. It has Vbat which isn't even universally featured on specialised FCs, and using a diode to prevent USB powering the whole system is a painful reminder of the missing-diode on Naze32 rev6 prototypes. Many ppl are commenting about WIFI control link. My inner FPV pilot says it's not feasible, but my coder personality tells me to look into ESP8266 or XBee lol

Mr. Joop, I am an Elect. Engineer and a keen learner of something new, even at the age of 68 yrs. I also launched a plateform for free education preferably for poor students. I started learning this drone projects just 2 months before. But got made succefully with help of your videos (the best I came accrross). Very easy to follow up. The best , smooth & easy way as you explained . My motto is to make drone videos in Hindi language using your principles after getting full confidence and doing some experiments following you. Can I ? Sir, I tried with the way of Mr. Andrei(Electronoobs) videos based on MultiwiiConf, but could not get success to operate drone as no PID signals from hand made remote controller 6ch. to FC. I do not know what mistake I am doing. Kpt working 2 months without success. and with your videos got success in 2 days only. He is also not able to understand. Seems code and Confih.h settings. Can you guide related to Multiwii drones. ? Pl sir I want to to know the very cause of failure. I could find your videos/website related to this. Thanks to you and your Plateform.

[@louigi6001]

if you use the 5V output from the Battery Citcuit Eliminator (BEC) in any one of the ESC you should be able to power up the Arduino NANO/ProMINI without issues (just make sure that you choose a 5v ProMINI version) ... it will be much smaller and lighter then an UNO but still retain the same I/O capabilities of the UNO.

[@kevinpinheiro2485]

I actually had shortage of time. This was for a college project. So I just went with the kk 2.1.5 and it worked surprisingly. I learned a lot from ymfc. Overall it was good lessons but I just didn't have enough time

[@makarthur4618]

Would like to have your validation of the power supply redundancy. Instead of just connecting two lipo in parallel, a circuit is built to control the power supply of two 6S lipo A and B. By default the copter will get power from the power reserve (capacitor) that initially draw current from lipo A. As lip A's voltage drops to say 21 volt, the system will automatically switch to draw power from lipo B.

[@davies8ter]

Hi there, I'd like to start by saying thank you. I have watched this entire video series and its been amazing! I do have one question though. In your schematic it shows you wiring your gyro to Analogue pins 4 & 5 yet in the video you instead connect them to the pins above Digital pin 13. What pins do you use and why these pins instead of Analogue 4 & 5? Thanks

[@Joop_Brokking]

There the same pins, only on different locations ;-)

[@MrKingDelight]

Thanks for you videos en website! I'm currently building one of my own. The ATmega on the Arduino is getting really hot within seconds. After some testing it doesn't get hot anymore and I probably broke it. On google I read that some pins might be drawing too much current, but I've followed you schematic. Any pointers on where things might have gone wrong? Bedankt voor je hulp!

[@lojo11audio]

I am currently constructing a quad copter based on your design. I just need to clear something up regarding the ESC signal wires. The ESCs I have came with a three prong signal wire and I am wondering how exactly you condensed yours down to one wire. Did you strip those wires back and solder all of them together to a single lead wire or did you just use one of the wires out of the three for the connection to the arduino? I guess I am just confused to what each of these wires represents for the ESC. Any explanation would be much appreciated.

[@samehaissaoui5784]

good work but i have a question , i didn't understand how did you choose the direction to fix the gyro because it depends on the motors as i know

[@Joop_Brokking]

It depends on how he gyro data is used in the program. And how the program controls the motors. With the YMFC-AL the orientation of the gyro is not important anymore: kzbin.info/www/bejne/eorTeXVjgcufpas

Hello Joop, Thank you very much for your videos. It seems that these ESC ground lines are not connected to GND of Arduino. Is that a right wiring?

[@Joop_Brokking]

[@kerricbennett5350]

Thanks for your quick response. i downloaded the ESC calibration with no errors. Then i noticed that when i plug in my battery I'm not getting power to the Arduino nor the receiver. im going to check my connection.

[@qmu2]

Hello +Joop Brokking In your video you are using L3G4200D but in ((Project YMFC-3D_Q&A_#8)) in your website you changed the gyro from L3G4200D to MPU-6050 ? and Why did you connect the voltage divider resister connection to A0? Thanks

[@Joop_Brokking]

The MPU-6050 is cheaper and is used for the YMFC-AL. Check step 3.1 on this page for the voltage divider: www.brokking.net/ymfc-al_main.html

[@blacksabersword]

Hi Joop, how do you connect your ground wires to a single arduino ground pin? Do you solder the ground wires (E.g. all the ESC ground wires) to a single wire and connect it to the ground pin on the arduino?

[@qmu2]

Hello +Joop Brokking why did you add diode in 6:39, and how you calculate and choose the two resisters in 5:26 ? Thanks

[@GrantSchulte]

In the pictures on your website, the small ground wire in the 3-wire cluster of the ESC (Electronic Speed Controller) does not appear to be connected to any ground. But in your schematic, it shows that the ESC small ground wire is grounded. To be safe, should we connect the small ground wires directly to the PDB (Power Distribution Board) where the large black ground wire is? Thank you in advance for the help :)

[@VforViktor5]

Thank you for this series! Very helpful! I am having a hard time with the ESC's though. I understand that three of the wires go to the motors, but on the schematic it seems as though the positive lead to power is not connected. I was also unsure of why there is only one wire for Sig on the ESC going to the arduino. Is this one of the wires that would be usually go to the flight controller?

[@Joop_Brokking]

On the schematic only the control wires are shown (small connector that goes to the flight controller). The manual of the ESC should give you enough information on how to connect the main power.

[@guitarockdude]

The schematics show the gyro connects SDA to A4 and SLC to A5, but you never connect anything to A4 or A5. Even in the other videos where the gyro is being programmed. Am I missing something here? What do you connect the gyro to?

Hi sir, im newbei on arduino uno.. it is possible to install camera on the arduino then it connect on the cellphone?.. do you have a video for that?.. thanks for the feedback

[@pasindukollure1278]

Since the lipo battery is powering the Arduino, is it possible to cut a 2.1mm barrel jack to USB cable and solder the wire end to the positive end (positive end on the frame at 6:33) of the battery?

[@Joop_Brokking]

USB = 5V, the battery is 12V so it will not work.

[@rajk5326]

Hi, Thanks for excellent videos. I'm trying to build my own quadcopter. I'm facing a problem with the IMU (Gyro,Accel) measurements.

[@hongingthorng5198]

Can you give me some guidance if I want to build a coaxial drone with just two brushless motor and servo? Will your code still be applicable? Another question is, in your video, you didn't use any distance sensor. It seems like the gyro sensor can handle everything so do you think distance sensors aren't necessary?(like moves away from walls if the drone is 1m close)

[@aaronlowe3156]

I'm going to be using the BEC from all 4 of my ESCs to supply 5VDC to the Arduino. For the A0 input, can't I just mount the 5VDC rail to it, without a voltage divider?

[@sgrpatil41]

I have a question about the power supply in your YMFC drone. If you are using lipo 3s 30c, its max output voltage is 12.6V which is more than the max input voltage rating for Arduino UNO. So, how did you manage it? What can I do to prevent it from damaging my Arduino UNO.

[@GrantSchulte]

I am new to arduino and hardware generally. Question 1) How was the ESC connected to the arduino? At 6:31 in the video, it appears that the ESC's 3 small wires (brown, red, and yellow) branch into 1 yellow wire. How is this junction created? Question 2) In addition, how is the motor connected to the ESC? The motor has 3 wires and the ESC has 3 inputs (U, V, and W). Which wires go into which inputs? Thank you so much for your time, I really look forward to experimenting with this build myself!

[@robsmit932]

All ESC'S are connected to the PDB (power distribution board). The F450 frame has an integrated PDB. If you have got a frame without PDB, you'll have to buy a seperate one. Three wires of each Bec are connected to the motors (one site has three lines, connect those to the motor, which has also three lines). The other two lines are connected to the plus and minus of the PDB. The BEC to Arduino with Arduino shield. Don't use the middle line of the BEC (5V), only the signal line and the ground line. From the PDB two extra wires to the VIN (+1.5K) and to the GND (+1k) of the Arduino Uno. Both resistors (1,5k and 1k) are connected to A0 (analog zero line of the Arduino Uno). For most motors, you can switch the outer lines for make them CW (clockwise rotation) or CCW (contra clockwise rotation). The middle line is the signal line, don't switch this one. Whatever you do, please hold on to the scematic of Joop Brokking. Use for the gyro a clear 5V-line and GND-line (with a Arduino shield you'll have planty of 5V and GND lines). Keep the lines of the gyro short, as well as the receiver lines. Have fun, it's a great learning experience, which took me three quarter of a year to understand and built it. Joop Brokking did a very good job.

hello...i am working on the same project of your YMFC3DV2...i had followed the same procedures as in video...but i am having 1 difficulty in the setup program..."move all the sticks to their extents simultaneously"i canot get the perfact values i.e 1000-1500-2000 bur it comes 1000-1500-2000 1500-1500-2000 1000-1500-2000 1500-1500-2000 something like this...can you help me with the procedure of moving knobs of flysky remote while doing this setup!?

what if Im using a 4s battery, which part of the sketch do i need to change? and what is the adjustment i need to do in the hardware?

[@Duckferd]

Feeding the Arduino using the 11.1V battery is through the Vin voltage regulator, correct? Is there a reason you don't recommend using the +5V BEC? Reason I ask is because I'm planning on using a Arduino Pro Mini for this project, but the voltage regulator on it is too tiny to last long at 12V. Meaning I would either need to build an external regulator if I use 11.1V.

[@Joop_Brokking]

You could use the BEC of the ESC. But the voltage regulator of the Arduino will give you a cleaner (less noise) voltage.

helllo thanks for the video, what motor used? 1200kv? And propellers used? and battery used? which battery I can Use? thanks very much!

+川崎春と Check the specs of the DJI Flamewheel 450 rtf kit.

How does one incorporate a camera? I believe that's the main point of the drone to capture images

[@wisbert]

Do you think PLA 3d printed arms would be strong enough for this project? It seems like there would be a lot of force on the arms

[@Joop_Brokking]

The whole quad weights about 1200 grams. That's 300 grams per arm during normal flight. Full throttle might be double that. So if you have a good construction design a 3D printed arm will work. If it will withstand a crash?... you just need to try it.

Thanks for the video, it was very informative Have you made a flight controller for a brushed motor quad like the Syma X5SW quadcopter, the quad has 8x20 MM motors, they cannot lift much weight, I notice that most people design around brushless motors, do you have any design tips for the brushed motors ? I am thinking of using a ESP-12 (ESP8266) board, this is tiny light weight, has sufficient PWM outputs and a Wifi transceiver on board. For driving the motors I thinking of a NPN transistor based drive, the ESP would PWM the motor for speed control, for accelerometer I have a GY-521 board. Do you think the idea is workable ? thanks

[@Joop_Brokking]

Brushed motors will work. I'm currently working on a small quad with brushed motors but it's far from ready. But it wil work.

[@walterbenitez8296]

Hello Jon, i'm building my own quadcopter flight controller too and i want to ask you how do you control your motor. I'm using the PWM function analog write to control it. To found how to regulate the PWM i use a linear interpolation of the motor speed. Another problem that i found is when i filter the signal. I am using the Madgwick filter and the sample rate decrease to only 80hz, is that enough in your experience?. And how do you add other functionalities with such a low sample rate.Pd: I am using the Plus configuration

[@Joop_Brokking]

Walter Benitez I'm still working on this video session. The esc's and how to control them will be discussed in part 4. Using the pwm function is not necessary and will cause unnecessary interrupts. For this project I just make a pulse with the timer. The sensor refresh rate and esc correction refresh rate should be a high a possible. 80Hz is to low in my opinion. The YMFC-3D project runs 250Hz for sensors and esc's.

[@enriquecerda1]

Hi, I have one question. In the video you are saying you are using the UNO cause it has superior capacity of outputting more than 150 mA. I was just taking a look at the UNO specs, it says it uses LP2985-N regulator which also has a max capacity of 150 mA... did something change on the spec?

[@Joop_Brokking]

The LP2985 is used for the 3.3V rail. The 5V regulator (the one I was talking about in the video) is the NCP1117.

[@harshachessie6456]

Hi there Joop! Thank you for this wonderful video! Is is really important to upload ESC calibrate program? Binding is enough right? one by one ! can i directly jump to set up program? please do reply!

[@robsmit932]

First: SETUP-program. Second: ESC-program (and ESC calibration). Third: FLIGHT-program. You'll need the ESC-program as well according to the three steps. Calibrating is possible after uploading all programs. I wouldn't advice it. Particular steps has to be taken, otherwise one motor runs faster than another. That is what you want to prevent. Good luck.

[@eversthomas]

i want to connect my esc to my brushless dc motor (got the one u recommended on ur website) buti read something about only connectin 2 wires insteaad of 3? do u mean the 3blue wires on the esc? wich one should i leave out then? and connect to wich color of my motor? THX :D

[@Joop_Brokking]

With a brushless motor you need to connect all the three wires from the motor to the ESC.

[@kevinsi5194]

HI +Joop Brokking, I'm going to build a quadcopter for my last school year project, and I'm starting to make the list of the component that I will buy, but when i was checking the specs of the components I saw that the esc's that I was looking at has an input frequency of 8-16Kz(I tought "what tha heck!!"), but the arduino's servo library has a refresh rate of only 50 Hz, and now im really afraid that if I buy that esc the whole system won't work, obviusly when I mean ESC, ^'m refering to all the esc. Are ther any ESC made just for Arduino? I was thinking of buying the Turnigy plush 30 amp, HK F-30 amp esco or the Afro esc 20 amp, both of these have an imput frequence of more than 1khz. what should i do?

[@Joop_Brokking]

+Kevin Silva The 8-16kHz is the switching frequency of the esc. This has nothing to do with the 1000 - 2000us control pulse. Most esc's that run Simonk or BLHeli will work fine up to 400Hz control pulse. Don't use the servo library with the 50Hz refresh rate. This is to slow and as you can see in the code of part 6 there are easier ways to create a pulse @ 250Hz.

[@kevinsi5194]

ah ok, so wich should i choose? I need to save money, so need something of good quality but that also good performance, will the HK esc be good? and THAnks a lot for your help

[@Joop_Brokking]

Yes, the Hobbyking esc's will do fine. You can also check Banggood.

[@kevinsi5194]

thank you very much, finally I end up with the choice of the HK esc, and I've flashed them with simonk and works amazingly

[@Joop_Brokking]

Kevin Silva That is good to hear!
