Hearing about how smart homes make life easier and safer got me excited, so I decided to build my Smart Home Automation System with an Arduino Uno. I wanted to use a switch and a potentiometer to control LEDs like they’re lights or fans in a house, showing how cool tech can be. It’s been fun learning how to make everyday stuff work with code!

I set up my Arduino Uno with a switch, a potentiometer, some resistors, and a few LEDs to act as my smart home devices. The switch turns an LED on or off—like flipping a light switch—and the potentiometer lets me adjust another LED’s brightness, kind of like dimming a lamp or slowing a fan. I used resistors to keep everything safe, and my code tells the Arduino how to read the switch and potentiometer to control the LEDs. It’s simple, but it feels like I’m running a tiny smart house!

I’m thinking about how to make this even more awesome next time! Maybe I can add a buzzer to sound like a lock clicking, or use more LEDs to pretend they’re different things like a thermostat. I could also try showing “ON” or “OFF” on my computer screen with the Arduino. I’m happy I’m learning how coding and wires can make a smart home with my Arduino Uno, and I can’t wait to show my friends how my lights turn on all by themselves!
