NRF24 receiver TEST code


NRF24 receiver TEST code


Download the .zip file below. Open it on your Arduino IDE and upload it to the Arduino on the TEST breadboard for the reciver.




This code is for the schematic.







/* Receiver 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 receive 1 channels and prints the value on the serial monitor
