Circuit Documentation

Summary

This circuit integrates an Arduino UNO microcontroller with an NRF24L01 wireless transceiver module, an L298N DC motor driver, a DC motor, and a 9V battery. The Arduino UNO is responsible for controlling the motor through the L298N driver and communicating wirelessly via the NRF24L01 module. The 9V battery provides power to the motor driver, which in turn controls the DC motor's operation.
