Circuit Documentation
Summary
The circuit in question is designed to control multiple DC motors using BTS7960 motor drivers, which are interfaced with an Arduino UNO microcontroller. The circuit also includes ultrasonic sensors for distance measurement and a Lipo battery for power supply. A rocker switch is used to control the power flow from the Lipo battery to the motor drivers. The Arduino UNO is responsible for controlling the motor drivers and reading data from the ultrasonic sensors.
