Additional Notes

• The provided code is a template and does not include specific functionality for the NRF24L01 module. Users should implement the SPI communication setup and data handling within the setup() and loop() functions, respectively.
• The Arduino Nano is powered through the USB connection or an external power source connected to the VIN pin.
• The NRF24L01 module is powered by the 3.3V output from the Arduino Nano to ensure proper voltage levels for the module.
• The IRQ pin of the NRF24L01 is not used in this circuit configuration. If interrupt-driven communication is required, additional wiring and code modifications are necessary.
