Smart Home Lights project for kids

Overview

This project is about smart home lights which are going to be the future as in these homes we don’t have to switch ON/OFF the lights as whenever the button is pressed remote lights will turn ON/OFF.

In these smart home lights whenever you press the button on the remote the lights will get ON/OFF in the future world of automation everything must be automatic.

Hardware required 

• Arduino Uno R3
• Resistor
• Jumper Wires
• IR Remote
• Led
• IR Sensor
• Breadboard

Precautions

1. Connections should be done properly.
2. Arduino is case Sensitive so code accordingly.
3. Give different and appropriate colors to the wires.
4. Use resistors for sensors and LCDs.
