Hi there. Be sure to carefully check and troubleshoot your wiring that it goes along whats on the diagrams and that your boards are getting sufficient power. Check that you've typed in the correct Arduino board pins in the code for both the Transmitter and Receiver. Just a couple of important things to take note of when checking for what can be wrong.

For that many inputs and outputs, use a Mega 2560 instead of a regular Arduino. Look for troubleshooting tips on the NRF24L01 online (in the web) to solve your issue. It's down to how you connect it. These modules are very sensitive.

Cool video! One thing I want to clarify is that trick with capacitor. I have recently tried connecting 2 such nrf24l01 modules, but with no luck. I only managed to make them communicate once and never again. Then I saw this trick, so now I have ordered the capacitors and will see if it works. I am just curious if it is normal that these modules fail to communicate without capacitors? I thought that the presence of the capacitor is not that critical, so it is more about making it work better, but not about making it work at all...

[@MaxImagination]

Thank you! The reason why adding capacitors often solves the signal electrical noise issue is because it filters the ripples and allows for a stable voltage to remain. Another trick you can try is twist MOSI and MISO wires with ground in a 3-wire twisted bundle to help rid those communication lines from noise. Try it :)

[@MohammadShayaanAnsari]

I tried to make this transmitter and receiver and my wirings are correct, code is uploaded properly and it is getting enough power but the servo attached to receiver is not working. Can you help me ?

[@MaxImagination]

Sometimes servos tend to stop working due to a break inside where the wires connect to the board, could you check that? If not that, then I suggest you hook up a multimeter and measure if you're even getting a signal from the Arduino's pins. It may also be your transmitter's NRF24l01 that's not transmitting. It may help to add a 10 microfarad capacitor to its 3.3V power terminals.

Is the 3.3V voltage regulator mandatory since the arduino nano has both the 3.3V pin and the 5V pin so it can be conected to the nrf module and all the servos or motors.

[@MaxImagination]

Not mandatory, but recommended for a more reliable supply. I suggest placing a 10 microfarad capacitor for power ripple filtering at the power terminals of the radio module if you're powering it from the Arduino's 3.3V supply.

can we connect brushless motor to reciever?

You can, but you'll need to connect it through a brushless ESC. Cheers, Max

can we use a simple rocker switch instead of that one for the transmitter??

[@MaxImagination]

Yes. Any on/off switch with a higher current value than 0.5A will work.

Hello! Thank you for the video, it was very informative, however i have a problem when uploading the file to my arduino, it is showing me the message "avrdude: ser_open(): can't set com-state for "\\.\COM3" " can you please help me out on this problem, would very much appreciate it if you could. Thank you in advance

[@MaxImagination]

Hi there. Thanks for your comment. Have you tried a different cables? Another Arduino? Sounds like your IDE isn't recognizing the Arduino due to a communication error.

[@E-_-waste_unofficial]

Are you sure you are using the correct com port? Sometimes arduino IDE can have trouble finding cheap/damaged arduinos

[@yuvarajyuvi592]

One more doubt brother, which channel ESC should be connected in ur circuit and code?

[@MaxImagination]

If you're using a PWM ESC, keep in mind that it can be connected to any channel above the 1st one (first one or two channels are PPM, not PWM channel).

[@kdt85]

This is so cool. Do you know if the transmitter will work between boards? Arduino namo and a pi pico for example?

[@MaxImagination]

Hi. Good question. I have never tried using the RPI Pico in a project before. You may need to research that board with NRF24L01 communication a bit more.

[@donatoae2433]

I think so your circuit diagram is incorrect because the 5v coming fron the esc would directly go to the 5v pin according to your circuit diagram but it should go to vin pin in the arduino i have burnt 3 arduinos because of this but now its ok

[@MaxImagination]

The method I show has never burned my Arduino boards, personally. Maybe that happened to you because you drew more than the 1 amp that the ESC's BEC could output? Consider checking that first. Cheers.

[@donatoae2433]

You need to download the NRF24L01 library from the IDE's library manager.

[@Iska-k5x]

Hello sir. What is the range of the remote???

[@MaxImagination]

100-1000 meters. The exact range you get will depend on how well filtered the power is to your radio modules and the environment you're testing them in.

Hey max, May I know the the size of the wires you use to solder the batteries together and any other wires you used other than the 30 Gauge wires you have listed in the video. Thank you so much.

[@MaxImagination]

Hi there. I used 20-gauge (20AWG) Wires for wiring the battery. I typically use 24AWG wires for my circuits which are a bit thinner. Cheers.

[@iyasmusallam1766]

@@MaxImagination Did you use the 24-gauge wires to wire all of the circuits in the video along with the few times you used the 20-gauge wires and the 22-Gauge copper wire? Can I use 22-gauge wires instead of the 20-gauge for the circuit and battery or will cause some issues? Also is it possible to use a stripped down solid core 22-gauge wire instead of the copper wire?

I don't have a laptop or computer to program I have only phone i don't know if it's work because the program in your laptop is not same to my phone to program the transmitter and receiver please help me

Max I have made the transmitter and receiver but it didn't work I have tried to troubleshoot the problem but didn't find it I have checked both of my modules They are perfectly fine and my receiver is not working when I connect the servo it starts moving by itself can you please help me to find the issues it would be a great help

[@MaxImagination]

Hi there. There is no one answer I can give except to check your Arduino on the receiving side and the signals it's outputting with a multimeter. Ensure your transmitter's NRF24L01 uses a 10uF capacitor at its power terminals for power filtering. And make sure you're powering each radio module with a stable 3.3V - I recommend using an AMS1117 regulator. The Arduino's 3.3V supply may not be enough in your case.

[@Alihaider10109]

Hey if I make a transmitter from someone’s else video will it work on this reciever😅😅

[@MaxImagination]

It may, if you adapt the pinouts in the code. Also, the codes must match to one transmitter and receiver pair.

[@Fiverr4364]

Why are you using D9,D10 pins instead ofD7,D8. Some tutorials they use D7 and D8 pins ?

[@MaxImagination]

It does not matter which of those pins you use for the CE and CSN connections. Both work.

Not possible with those Arduino's alone due to the limitation in pins. However, you can do it if you used 2 Arduino Mega boards or a microcontroller with more free IO pins.

What is the range of transmitter and receiver it is good for rc plane or not

[@MaxImagination]

The range really depends on good antenna power supply (Voltage and current), as well as what filtering capacitors you put at the power input terminals of the antenna module. So to answer your question, the range is pretty good, 120-1000 Meters.
