Summary of the Circuit

This circuit consists of an Arduino UNO microcontroller, a Piezo Buzzer, and an IR sensor. The Arduino UNO serves as the central processing unit, controlling the behavior of the Piezo Buzzer based on the input from the IR sensor. The IR sensor detects infrared signals and sends the data to the Arduino UNO, which then decides whether to activate the Piezo Buzzer. The circuit is powered by the Arduino UNO's 5V output, and the ground connections are shared among the components.

Component List

Arduino UNO

• Description: A microcontroller board based on the ATmega328P.
