Summary

This circuit is designed to control a servo motor using an Arduino UNO microcontroller. It includes a toggle switch to control the power flow and a relay module to manage higher power loads. The circuit also features three red LEDs and a buzzer for indication purposes, all powered by a 9V battery. The Arduino UNO is responsible for controlling the servo and potentially other logic functions as defined in the embedded code.

Component List

Arduino UNO

• Microcontroller board based on the ATmega328P
• It has 14 digital input/output pins, 6 analog inputs, a 16 MHz quartz crystal, a USB connection, a power jack, an ICSP header, and a reset button.

Servo

• A rotary actuator or linear actuator that allows for precise control of angular or linear position, velocity, and acceleration.
• It consists of a suitable motor coupled to a sensor for position feedback.

Toggle Switch

• An electrical switch that is manually actuated by a mechanical lever, handle, or rocking mechanism.

9V Battery

• A standard size of battery typically used in small electronic devices, smoke detectors, and clocks.

LED: Two Pin (red)

• A light-emitting diode that emits red light when a voltage is applied to its anode and cathode.

Buzzer

• An audio signaling device, which may be mechanical, electromechanical, or piezoelectric.

Relay module 5v-30v

• An electrically operated switch that allows you to turn on or off a circuit using voltage and/or current much higher than a microcontroller can handle.
