Turn ON-OFF electric appliances using any IR remote control

By this Arduino project you can run any electric devices (AC and DC) by using any IR remote control in your home. (remote control of TV, satellite, air conditioner, etc)

Since each IR remote control button have certain frequency, so you have to determine that and put that in the code.
 

You have to follow this steps:

1-connect your relay module (or LEDs) and infrared receiver module to your Arduino board as shown in following figures

2-then upload the code (in below of this page) to your Arduino board and open the serial monitor

3-then press any button of your remote control (put the remote toward the IR receiver)

4- put the number that appears in serial monitor (in prior step) in your code and repeat this work for each buttons then upload the code again

 5-Now it is ready to use as you can see in following video, when you press the button key, the load that connected to that pin turn ON and by other press it be turn OFF.

Note: you have to add IRremote.h file to your Arduino library, Download it from here
