Arduino drone - Part2 Transmitter & Receiver

[@andrewkasza7282]

I had tried to build a Arduino controlled quad a couple years ago, and I just got a 3d printer and I found your videos on this build. This will help allot in finally finishing my project. Thanks.

[@TanishqIsHere]

*I just cannot thank you enough for this! was searching for this since the beginning of time*

[@lebasson]

Congratulations on this series. The pacing and visual way of presenting the information is so good!

I want to build this great project! 😊 thanks for sharing it

[@njamnjamb]

How to use test values? Mostly I don`t understand what should I do to correct unproper middle position.

[@cesarhinojosa1968]

hello, awesome job!!! but i have a question why have you soldered 5V to VIN on the receiver, we get VIN from the lipo battery, but i dont get that connection, the 3.3 voltage regulator goes from 5V or from Vin(sharing the connection)_

[@robertparenton7470]

Thank You! From Frisco, TX

[@hondatechnodiag8495]

wow you r amazing teacher tank you very much this series Really helped me in the completion of the end of the study I hope you put a smooth internet stuff I really liked your methodology in communicating the idea to the recipient

[@santtappamulage6083]

Sorry sir I not understand that port 1,2,3,4 which one where should connect

[@sharmabhumi8174]

test code only working and when i connect it digital pin 2 with reciever code it won't works at all i tried alot but no output is recieved

[@ELECTRONOOBS]

The receiver doesn't work? have you tried first the receiver test code to see if you receive the values using the serial monitor of the arduino?

[@sharmabhumi8174]

Electronoobs yes reciever receives the values perfectly and if PWM code is uploaded then also works fine but ppm is not giving output and for reciever m using atmega328 dip not nano

[@t41ef46]

I followed every step of each video twice. But it still is not working for me. The software shows the controller is working but the motor doesnt respond. Sometimes, I just get random fluctuating behavior from the motor. Any advice is highly appreciated!

[@app213]

Amazing tutorial. Could you maybe make a tutorial on showing how to connect a JR module to a diy Arduino tx controller?

hi..... the transmittor code and receiver test codes are compiling correctly but the actual receiver code is have some #error statement which is giving an error indication. Help me out.....

[@abhishekmeena8019]

This vedio cleared all my doubts but i have 2 ques.. Can u please explain me the concept behind the ps/2 port??? Also, should i use both joystick and potentiometer or only TWO JOYSTICKS ARE SUFFICIENT as your coding indicates the use of 4 joystick values (or potentiometer values) and one joystick have 2 potentiometers corresponding to 2 potentiometer values.

[@MrAidit]

i want to use oscillator for the 6th channel for controlling gimbal. can you help me which part i should modify in the code?

[@dushyantchaudharymathura]

Hi, when I use arduino nano instead of atmega chip in the transmitter, would the same transmitter code work or there is a separate version for arduino version.

[@giniterminator]

Very good video and explanation! Congrats!

[@pocat00]

this is a really awesome video. where do you solder the trim wires on the Arduino Nano. because I would like to ads trim. would i need too change the code.

[@vasyapupkin911]

thank you this is a great job. Tell me please, can i use a LoRa receiver and transmitter instead of nrf24?

[@saadkarim6994]

this is very good job and i want to start building it this summer

[@BarefootBeekeeper]

Here's a question for anyone who knows: what happens with the trimmers on the transmitter when you convert it to Arduino? Can they be incorporated into the circuitry so they can still do their job? If so, how are they connected? If not, how do you trim the quad before/during flight?

[@originalthehrao]

Dont think that you would need a trimmer with flight controller on board. You can add code to your flight controller to auto trim if its not already taking care of the trimming.

[@dipakpatil3529]

Pleas tell me the function of each potentiometer and switch. Like a which potentiometer is use for forwarding the drone and which is for reverse ,up and , down ?pleas reply

[@andrew_with_laser_eyes]

Hey Electeonoobs, this really interests me. Is it possible to use a frsky transmitter module and receiver module to hack something together using Arduino to get that reliablitity/long range signal and be able to make a custom controller? I've been trying to figure this out for a while. Thanks

[@shantotorofder3916]

Hey can i use arduino pro mini to make the receiver....... If I can how many voltage regulator I have use....is this I have to use one voltage regulator for nrf and other for arduino pro mini..........I just want to know that arduino pro mini has voltage regulator or not..

[@casandrachavez9298]

hello sir, this transmitter and receiver are the same in your DIY transmitter and receiver

[@abhishekshadagali]

Is transmitter construction is same for brushed and brushless drone

[@ayushmanjain4008]

receiver and transmitter antenna can be of different size or the size should be same to get a longer range?

[@aminezitouni8427]

could you tell me how can i change the receiver code to get the PWM at 1520us center pulse? Because The software that i use on my flight controller requires a receiver that supports a 1520us center pulse. what can you suggest me? please answer my question, thank you.

[@sonaliganje726]

i have followed all your videos , i am getting 6 channel ppm data on my serial monitor with reciever test code but when i upload the final code to the reciever i cannot see the the recieved data on the multiwii platform ... i have used two arduino mega instead of arduino nano ... can u pls help me out

[@zfazir6903]

in this video, are you still use arduino uno and arduino nano? because you not mention the material of arduino uno

[@kerricbennett5350]

you 3.3 voltage regulator looks different in the receiver schematic than in the link given above. Is it the same? And, what type of decoupling capacitors did you use? thanks

[@omsingharjit]

Nice , & thanks :) i wanna know , is it possible to somehow use Computers joysticks or Gamepads , as Arduino projects controller ???? i mean can we connect joystick's Usb to some usb compatible ics like Attiny85 and use its whole buttons and potentiometers ???? because by this way perhaps we can use is A , B , C , D , and Up , Down , Left , Right and other push buttons , with any Arduino projects !!!!?????

[@edwalsh18]

I am also interested in this

[@diegojosephia]

It definitely is possible we just don't recommend it, it feels way different and not in a good way😁 but you can always try

[@jkimmmusic]

Can I use the PPM output from the Nano into a regular FC?

[@ahmedmujahad9999]

in this video you have solder 5v port with vin but in your blog you didnt mention about this??? can you explain the purpose of ppm port attached to d2 on nano? where to attach it ?

[@ELECTRONOOBS]

I never solder 5V to Vin, That's crazy. Maybe two lines overlap on the schematic by error but never connect 5V to Vin. The PPM sends 8 channels with the data to the Flight controller, it's basic!

[@ahmedmujahad9999]

see the video at 10.30 of part 2

[@ELECTRONOOBS]

Don't worry about that. It was a small error, the voltage regulator wasn't working si I'e soldered a jump wire between Vin and Vcc, I forgot about that. But you just follow the schematic. There is no connection between Vin and Vcc. Thank you!

Question: Why do you have to make your own radio controller? Why can’t you use the one without modifying it? I’m working on a project and I want to just buy a controller and not have to make one. Can you buy a controller and somehow connect it to a receiver which is connected to an Arduino?

[@abhishekmeena8019]

There are many sites like mydronelab.com, etc where u can refer. Because they use ready made transmitter and receiver. This site uses diy made receiver and transmitter.

[@shantotorofder3916]

So after inject the code into the receiver and transmitter how you connect to the receiver with that transmitter.......... like how you bind the transmitter with the receiver.......... I am simply saying I am using nRF24L01+ integrates a complete 2.4GHz RF transceiver for to make receiver and NRF24L01+PA+LNA Wireless Transceiver Module 1100m for transmitter.........will it connect to each other................................. plz tell me....will it connect or there is a match like it have to same model...... if you say that it will connect not a problem I will order it from online......... so plz reply....

Is it possible to use telemetry on this receiver? NRF24 is a transceiver.

[@Taran72]

thank you for the video but your transmitter test code is the same as the receiver test code. I tried it and got a bunch of gibberish letters that scroll continuously regardless if the module is connected or not. I am not quite sure what should I see and if I have an issue with the module or with something else. thank you for sharing the code, it really helped. :) UPDATE: it turns out that I applied 5V instead of 3.3V on one unit so basically I fried one unit and had the other one works fine so probably that explains the erratic letters I was seeing. :)

[@imanamal5522]

How did you make the manual fine tune? You did not show how.😓

[@marklimbrick]

...all the questions in these comments, I know the answers, but you could easily google and find out yourself....eg Iman Amal - the joysticks have a mechanical link which moves the whole body of the 'pot' to function as the trim adjusters = manual fine tune? No extra 'trimming' pots, so this is more reliable way to do it. I point out that there is no hi-tech 'channel hopping' with this system, so you need to be real careful about checking maximum range, every time, before a flight!

[@glegoo195]

[@arduinotechnology9564]

It's cool but can you make a transmitter using arduino joy sticks

[@bendixsondermann8039]

Is there a way to wire the receiver to a Naze32 instead of arduino nano /pro mini? I have it set up, and think i see the noise jittering from the working receiver on the Naze, but cant seem to get the receiver and the transmitter to communicate. I have the Potentiometers setup raw, as im still waiting on my Joystick ones. Have everything wired according to your schematics, and flashed the according firmware to the Arduinos. Both NRF24 get their supply from the same 3.3 v ams1117 breadboard power unit. Nothing smoked or smelled funny. :D The Baseflight App shows no change upon turning the pots. I hope you have a suggestion how to get this to work ! :) (Loved your Idea of making Remote and Receiver myself, and so, customizable!) ;)

[@ELECTRONOOBS]

I'm not fully understanding you. The trasmitter/receiver doesn't work at all or it has errors? Your NAZE32 acdept PPM signal or it has normal PWM signal for each channel. Upload the transmitter code to the transmitter arduino and upload the receiver test to the receiver and check the arduino serial monitor. If that works, then upload the normal receiver code and connect the PPM wire to your Naze board. It would be nice to observe the signal on one oscilloscope. Any any other question just ask!

[@bendixsondermann8039]

Thanks for the fast Reply! :) Sorry, i will try to clarify a bit more! ;) In the Baseflight App, i set the Naze32 to PPM Input (which disables PWM) I wired the Receiver up, and the Baseflight App shows me slightly jittering Values, sitting roughly in the middle ( i have a lot of Interference here where i sit, as there is a wifi router nearby, and various Electronics, etc. The Jitter is small tho, from 1500 to 1501 and back, for example. When i turn on the power for both nrf24, the signal in Baseflight shortly jumps. Thanks,I will try the Receiver test , and get back to you! :) Sadly i dont have an Oscilloscope, but i would like to have one, someday. I only have a Multimeter at the moment. Lets see if i can get this to work. Its my first time doing this kind of build! ;)

[@ELECTRONOOBS]

But ignoring the small jitter the transmission works? I mean you slide the potentiometer and the received values change?

[@bendixsondermann8039]

ELECTRONOOBS, in fact it does not,and I still need to Try the receiver test Today. What it does is "spike" as soon as I connect the power to both nrf24 (in the receiver tab in Base flight) In my opinion, that means, the Naze at least has a working connection to its receiver (I think there is a problem in communicating between both the Nrf24. And I think the Problem might be on Transmitter side) I will be back home in like 2.5 Hours, and then I will tell you the results of the receiver test. Let's say, I get no output, at all. Even tho everything is wired correctly. What would I do then? I can make you as many photos as you need, if you want to see my setup. 😊

[@bendixsondermann8039]

ELECTRONOOBS, I got to hook up a joystick and it's button to the Arduino pro mini, tried to make the Nrf24 transmitter communicate with an Arduino Uno with the Receiver Test code on board. The Serial Monitor in Arduino IDE is connected, and showing Nothing. So there is no connection. What to do now? 😊

[@mihapeterle204]

on your web page is arduino reciver code for 6 servo controling, like normal rc reciver. whic one transmiter is the one that mach the code for reciver. I wll be glad for anie answer.

[@kjohn4687]

where can I buy that transmitter joysticks with the same specifications? is I need to change the program if I changed the specifications of the joystick?

[@ELECTRONOOBS]

Basically all joysticks are just two potentiometers so any RC controller should be the same. All that could be different is the quality and precision of the potentiometer movement. I bought mine from a second hand store!

Electronoobs Thanks for your kind information sir...✌✌:-)

how solid is the link! ...what is the range and what about interference from other transmitters nd wifi signals!? does it affect!?....plus can i use a 433mhz module and boost its power to 7W instead of a 2.4ghz....to get longer range like UHF system for fpv !?

[@ELECTRONOOBS]

Using 2.4GHz you will have no interference. You jyst have to use a different channel pipe. Using the module with the power amplified antenna I was able to keep the link for more than 800m.

[@rish1975]

800m is not gonna cut it nd 2.4 ghz can be used only winthin 1w power transmission beyond 1w is illegal .....its for my project i need range for atleast 20km.....nd 433mhz is the least used bandwidth.....is there any way by with i can transmit PPM signals for such long distance....and can u suggect me any other micro controller for 12ch ....a little tweak in the code should do it right!?.....nd can u explain if the transmitted PPM signal is converted to PWM signal at the receiver because servos work on PWM signals!?

That is optional. I don't use that function. www.electronoobs.com/eng_robotica_tut5_2.php According to 6.5 of the nRF24L01+ specification sheet, they translate to: RF24_PA_MIN=-18dBm, RF24_PA_LOW=-12dBm, RF24_PA_MED=-6dBM, and RF24_PA_HIGH=0dBm.

For even simple nrf24 tutorials. What am I doing wrong???

[@ELECTRONOOBS]

Ok so there are many reasons the radio could fail. I recommend you to first test the simple code of send and receive of only one data. Make sure the radio voltage is 3.3V and maybe use external regulator for more current. Use short wires between arduino and radio module to reduce interference. Make sure to select csn and ce pins in the code to match your connections, in this case as you say, pins 9 and 10. If still doesn't work, i don't know...

[@clintonsmith4166]

@@ELECTRONOOBS Well first I appreciate the response. I am using the nRF24L01+ Adapter that regulates the voltage and im using the 5v pin from the arduino nano. I have tried every simple test code I can find and I am certain about the csn and ce pins. I've heard that the market is flooded with cheap knock offs so I guess I am just going to keep ordering different ones until I find a good set.

yea i know and i have used regulator 3.3v but its still gets hot when i attach the 12v betray as shown in your schematics.
