SG90 Servo Motor

Functionality:

Converts electrical signals from the ESP32 into controlled rotational movement. The continuous rotation servos are used for the robot’s wheels, while the standard servo is used to pan the distance sensor.

Operation:

Servos use a PWM signal to control their position or speed. The ESP32 generates a PWM signal with a specific pulse width that corresponds to the desired servo angle or speed.

Control/Communication:

Controlled by the ESP32 via PWM signals.

Pin Connections:

Signal (Yellow): Connected to GPIO 5,6 & 7 (PWM output)
