NRF24 transmitter TEST code


NRF24 transmitter TEST code


Download the .zip file below. Open it on your Arduino IDE and upload it to the Arduino on the TEST breadboard with the potentiometer connected to A0.




This code is for the schematic.






/* Tranmsitter code for the Arduino Radio control with PWM output
 * Install the NRF24 library to your IDE
 * Upload this code to the Arduino UNO, NANO, Pro mini (5V,16MHz)
 * Connect a NRF24 module to it:
 
    Module // Arduino UNO,NANO
    
    GND    ->   GND
    Vcc    ->   3.3V
    CE     ->   D9
    CSN    ->   D10
    CLK    ->   D13
    MOSI   ->   D11
    MISO   ->   D12

This code transmits 1 channels with data from pins A0 POTENTIOMETER
