IR Remote Controlled Light and Fan Project

Arduino IR Remote Based Home Automation Science Project This IR remote-controlled light and fan project is a practical home automation science project designed using Arduino Nano. It allows students to control an AC bulb and a DC fan using any TV remote. When the user presses button "1", the AC bulb turns on; pressing "2" activates the DC fan. This project is ideal for school and college science fairs and robotics competitions in Bangladesh. Specifications: Arduino Nano board for IR signal decoding IR receiver module with included TV remote Two 5V relays for controlling AC bulb and DC fan BC557 PNP transistor for relay switching 1kΩ resistor and general-purpose diodes for safe relay operation DC motor with mini fan setup TP4056 module for powering via mobile charger (charger not included) 6Ω ceramic resistor to manage voltage to the motor Electrolytic capacitors for IR sensor and motor stabilization Standard AC bulb holder included (bulb not included)
