Circuit Documentation
Summary
This document provides a detailed overview of a circuit that includes a 5V relay, a MAHIR 1.mini power source, a piezo buzzer, and an LDR (Light Dependent Resistor). The circuit is designed to control the relay based on the input from the LDR and to activate the piezo buzzer accordingly.
