I always wanted to control my room remotely, so i decided to create a system that allow me to do it. If you want to learn how to? then i invite you to follow those steps bellow.
Step 1: Communication Technology
We could think that a cellphone app is the best option but no, no by now, think on that: We want to sleep, 12am at night, sleepy and then have to turn on our phone screen, unlock it, open the app, connect with the bluetooth module, and then turn on or off our light, this don't sound great, but, if we use Infrared remote controls we just have to click a button. So because of that in this tutorial we'll be using an Infrared remote control.
Step 2: Materials:
We just need a few things:
1-Arduino (no matter what model).
6-An USB cable to program the arduino.
Step 3: Diagram and Assembly
Step 4: Program and Code
You need to download IRremote.h library but that's all:
