This circuit is designed to control a set of DC motors using an Arduino UNO microcontroller and an L298N DC motor driver. It also includes an NRF24L01 module for wireless communication. The power supply for the motor driver is provided by a 18650 Li-Ion battery, and the Arduino UNO is powered by a separate 18650 battery holder. The circuit is intended for applications where remote control of motors is required, such as robotics or automated systems.
