In this project I will show you how I created an additional circuit for my speaker system in order to control it wirelessly with a homemade IR remote. Let's get started!

Step 1: Watch the Video!

The video gives you an overview on what you need to do to create your own IR receiver and transmitter. During the next steps I will present you additional information.

Step 2: Order Your Parts!

Step 3: Create the Circuit!

Here you can find the schematic as well as reference pictures for the transmitter and receiver. You can also find the schematic here: https://easyeda.com/GreatScott/IRRemote-j0cMKIGfh

Step 4: Upload the Code!

Here you can download the code that you need upload to your Arduino Pro Mini and ATmega328-PU before testing out your circuits.

Remember to download and include the necessary libraries in your folder:

IRRemote: https://github.com/z3t0/Arduino-IRremote

LowPower: https://github.com/rocketscream/Low-Power

Step 5: Success!

You did it! You just created your own IR receiver and transmitter!

<p>I just love watching these videos. Not only are they highly informative, but relaxing as well.</p>
<p>why IRsend irsend; on code doesn't work ,the problem say : 'IRsend ' does not name a type</p>
<p>I had the same problem, try reinstalling the ir library and delete '#include&lt;Irremote.h' and include it again with the Funktion 'include library' on the Arduino ide, then it should work ;)</p>
<p>thank you</p>
<p>Where in the code is the pin of the ir led stated? I can't seem to find it.</p>
<p>Look in the schematic</p>
<p>This one looks so creative..</p><p>I probably have to do a similar one in my set up soon...</p><p>Author- You have done a great job in power saving.. Thumbs UP</p>
