Arduino Nano-Controlled Servo and DC Motor with NRF24L01 Wireless Communication
Circuit Documentation
Summary
This circuit integrates an Arduino Nano microcontroller with an NRF24L01 wireless transceiver module, two servo motors, an L298N DC motor driver, a DC motor, and a 12V battery. The circuit is designed to control the DC motor and servo motors wirelessly through the NRF24L01 module. An electrolytic capacitor is used to stabilize the voltage supply to the NRF24L01 module.
