Summary of the Circuit
This circuit consists of an Arduino UNO microcontroller, an infrared (IR) sensor, and a buzzer. The Arduino UNO serves as the central processing unit, controlling the behavior of the circuit based on the input from the IR sensor. The IR sensor detects the presence of objects or motion and sends a signal to the Arduino. The buzzer is used to provide an audible alert when the IR sensor is triggered.
Component List
