The receiver is very simple. All we need is another Arduino, the NRF24 module, the voltage regulator and some pins for GND, Vcc and also PWM signal out. Solder everything on a PCB and upload the receiver code that you will find below.
This code will receive the values from the transmitter and create 6 PWM signals on some digital pins of the Arduino.
This code will receive the values from the transmitter and create 1 PPM signal on digital pin D2 of the Arduino.
And that's it. now you have a full radio transmitter and reciver. In the menu you could select the mode from lineal to exponential and fine tune each value. Have in mind that the middle value of each joystick should be 127. You can download all you need in this tutorial. Consider supporting me on my PATREON page.
