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

[@nombreapellido5125]

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...

[@Joop_Brokking]

+Carlos tercero A full lipo has a voltage of 12.6V, not 11.1V.

[@nombreapellido5125]

+Joop Brokking Thanks joop : )

[@Hellston20a]

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

[@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.

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.

[@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.

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.

[@lelegricc1520]

Thank you!! Im sure this will become huge!

[@seyedmohammadsadeghjalalza3728]

Thanks for your Tutorials. Why dont you connect the third wire of ESC to Arduino 5V? You left one pin of ESC not connected.

[@fotoamgamgfoto3695]

I am interested in your idea about my plans to make an autopilot system based on accelometer and gyro. What do you think can it work? Here is my plan: - having an arduino nano/mini and a gyro and accelometer sensor wired together - connecting that module between the receiver module and the flight controller - that module would store the path of the flight in 3D and could take the control of the copter in specific situation to return to home without using any magnetic or radio related module so no compass no GPS. Just store the path by the accelometers and gyros. (It could have to do some interpolation of the measured points not to store too much coordinates, so some kind of fixed resolution 3D curve.) There could be different ways to go home on loosing signal of the transmitter: - simple play back the curve backward - finding the easiest path (could fly into objects), like fly in a straight line on horizontal directions to the distance calculated until estimated takoff coordinate at current altitude then land The two above could be used in a mixed way or based on flight time or battery voltage. AutoPiloting the copter would be the tricky part. It should give pwm values for movement in a hardcoded range with a specified default and measure its accelometers/gyro and correct the speed in each directions and store the estimated path on the way home. I know based on compass and GPS it would be easier but there are situations when radio signals are yammed etc. So this is my idea, to store an interpolated path based on accel/gyro. Triggered by an event get the control over the copter in manual/stabilize mode and fly back home based on its accel/gyro. This way it would be compatible with any standard copter. Also with a 4 side sonar module and low speed it could have made more clever to avoid collision.

[@Joop_Brokking]

First you should get some live data from a accelerometer and gyro on a quadcopter. Try to figure out on how to use this data. You will see that this will be your greatest challenge. Try one thing at a time and slowly work your way to your goal.

[@fotoamgamgfoto3695]

+Joop Brokking I don't say that I can do the code, I am just interested in your opinion can it be possible?

[@Joop_Brokking]

What I'm trying to say: the accelerometer does not register turbulence, wind, drift etc. You will notice this when you play around with one. In my opinion it is not possible to do any return to home without a repeatable data source (GPS, distance + mapping, etc)

[@fotoamgamgfoto3695]

The connections of the motors to the ESC are all the same, or they change so that they turn to the contrary. I guess all the same and then with Arduino you order that each one turn different. Or changed connections and arduino all turn the same.

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.

[@MrFabiopcardoso]

[@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

[@H92GiGa]

Awesome Series. The best I found online. How are you powering the ESCs? The schematic only has the signal and the ground connected to the Microcontroller. Shouldn't you have to connect all 4 ESCs to the LiPo battery to supply it with power? Thanks for your effort in making this.

[@iswnsb]

Sir, first of all I want to say how much I greatly appreciate your video. They are truly amazing. I just got one question which is: what's the purpose of A0 port?

To keep a constant speed when the battery voltage is decreasing as shown here: kzbin.info/www/bejne/gHPZn3VmZ5xsY7M Also it gives the possibility to have a battery warning.

[@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.

[@SegaSeven]

Hello +Joop Brokking. I've been following your tutorial series and I'm very excited to say that I have successfully assembled my own drone to your specifications. I say "assembled" because I have not actually gotten it to fly. I'm using a 2700mAh Thunder Power RC 3SP+25 battery with a nominal voltage of 11.1v, and I see that, in your schematics, you have your voltage divider hooked up to both your battery's ground lead and also its positive lead after the diode and prior to meeting your chosen analog input on your Arduino. In your video however, you create the connection by hooking up the bottom of your divider to Vin and GND on your Arduino. I should also note that I've elected to use the 12v barrel jack on my Mega 2560 to plug my battery into my board. I'm concerned that by creating my voltage divider connection in the same fashion which you've created yours, I may short out my battery and start a fire. Is it safe for me to directly wire my voltage divider to a pair of extra leads coming from my power distribution board (battery) prior to hooking it up to my Arduino? Or would it be safer to use the Arduino's power ports to accomplish the task? Should your answer be the latter option, would I have to power my board in a different fashion? Thanks for your input Joop. SegaSeven

[@Joop_Brokking]

+SegaSeven I you use the power jack on the board the protection diode from my schematic can be discard. You can connect the voltage divider to Vin and GND of you Arduino Mega board. As you can see in the schematic the Vin is directly connected to the power jack of the Arduino: www.arduino.cc/en/uploads/Main/arduino-mega-schematic.pdf

[@SegaSeven]

+Joop Brokking Thanks for pointing me in the right direction Joop! I must also note that since I've used my barrel jack to power my board, I've used the Vin pin to power the gyro and other accessories. Will I still be able to use the same pin for the divider? I have mounted my board in an acrylic box which has a breadboard adhered to it. It's how I've been making my connections. I'm thinking that I'd create the divider using my breadboard by connecting the bottom of it to my Vin and GND buses, and then the top of it to my analog pin.

[@Joop_Brokking]

SegaSeven Don't use the Vin to power the sensors. This will destroy you sensors! As you can see in the schematic the Vin is directly connected to the power jack. Use the 5V or 3.3V (depending on the rated voltage of your sensors) output for this. Just connect the divider as shown in my schematic.

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 :)

[@buncho888]

Great project! Looking forward to see where this goes. At the start of the video you mention that the pro mini has a max output of 150mA. Is that a problem for this flight controller? Or does it only become a problem when you start adding more breakout boards like a GPS, altimeter etc?

[@Joop_Brokking]

buncho888 My receiver uses 85mA, the led 15mA. 20mA for the rest (processor, gyro, esc signals, etc). In total 120mA. So it should work with enough cooling. You can also power the Pro Mini with 5V if u use a esc with a internal 5V bec.

[@skmotiarrahaman2503]

I have the transmitters from drones I've broken, but how do you make the adruino actually receive the signals? Please provide the links to these in your description.

I did it it works great. But the only issue is that isn't stable during take off.

Amazing video, thank you very much. Keep going

Hi in the schematic you connect the gyroscope on SDA/A4 and SCL/A5, but in the video you conect in other side. What's the correct conection?

[@Joop_Brokking]

+Ninoshka Rodriguez Both connections are correct. The A4 and A5 are routed to the other side of the Arduino Uno.

you are awesome , awesome video thank you so much

[@Isotope1213]

on your schematic did you forgot to complete the power from the motors? you have only shown the ground been connected

[@Joop_Brokking]

I did not forget it. The schematic is just for the flight controller signals. In the manual of the ESC you can find the information about the motor / battery connections. And on this page I made a detailed build article: www.brokking.net/ymfc-al_main.html

Thank you so much. Your contribution to the tech world is hugely appreciated

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?

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

Can I connect resistors to positive and negative terminal of baterry?
