Circuit Documentation
Summary of the Circuit
The circuit in question consists of an Arduino UNO microcontroller, an infrared (IR) sensor, and a Piezo Speaker. The Arduino UNO serves as the central processing unit, controlling the behavior of the IR sensor and the Piezo Speaker. The IR sensor is used to detect the presence or absence of objects based on the infrared light reflecting off them. The Piezo Speaker is an output device that can generate sound at different frequencies.
Component List
Arduino UNO
- Description: A microcontroller board based on the ATmega328P.
