A beginner-friendly guide to build a hardware setup that senses room temperature and automatically turns on a fan with a red light above 25°C or a green light below.
How It Works
You find a simple DIY project online that automatically cools your space by turning on a fan when it gets too warm.
Collect everyday items like a temperature sensor, colored lights, a fan switch, controller board, wires, and a breadboard from a hobby store.
Follow the easy picture guide to connect the sensor, lights, and fan switch to the controller board on the breadboard.
Use the straightforward instructions to add the decision-making program to your controller board.
Connect to your computer and open the view window to see the live temperature updates.
Sit back as the green light glows in cool weather and the fan plus red light kick in automatically when it's hot, keeping everything just right.
