Circuit Documentation

Summary

This circuit is designed around an Arduino UNO microcontroller, which serves as the central processing unit. The circuit includes various components such as servo motors, sensors, a joystick module, an LED with a resistor, a buck converter, and a 12V battery. The Arduino UNO controls and interfaces with these components, receiving sensor inputs and driving actuators like servos and LEDs. The circuit is powered by a 12V battery, which is stepped down to a lower voltage using a buck converter to power the 5V and 3.3V components.
