Circuit Documentation
Summary
This circuit consists of multiple Micro Servo 9G motors controlled by an Arduino UNO. The circuit is powered by a 3xAA battery pack and includes a rocker switch for toggling the power. The servos are connected to the Arduino for PWM control, and the power is distributed from the battery pack to the servos and the Arduino.
