Circuit Documentation

Summary

This document provides a detailed overview of a circuit designed to interface with various components including a seven-segment display, buzzers, LEDs, an IR receiver, a relay module, and an Arduino UNO microcontroller. The circuit is powered by a 5V battery and a 12V battery, with voltage regulation provided by an SMPS (Switched-Mode Power Supply). The Arduino UNO is used as the central processing unit to control the components based on the inputs received from the IR receiver and to drive the display and indicators (LEDs and buzzers).
