Introduction: Control Your LEDs With Your TV Remote?! || Arduino IR Tutorial
In this project I will show you how I repurposed the useless buttons on my TV remote to control the LEDs behind my TV. You can also use this technique to control all sorts of things with a bit of code editing. I will also talk a bit about the theory of how an infrared transmitter and an infrared receiver communicates with each other. Let's get started.
Step 1: Watch the Video!
The video gives you all the info you need about the theory of this project and the practical implementation. So watch carefully.
But in the following steps I will also present you my parts list with example sellers and the schematic, code,.... to make your life easier if you want to build this.
Step 2: Order Your Parts!
Here you can find most of the parts that you will need to complete this buid (affiliate links).

Step 3: Build the Circuit!
Here you can find the schematic for the circuit. You can make your own board layout for this but you can also just use mine instead. It should work without any problems
Step 4: Program the Arduino Nano!
Here you can find the code/sketch for the Arduino Nano. Make sure you upload it before you start testing.
And don't forget to download the IR library for the Arduino: https://github.com/shirriff/Arduino-IRremote

Question 4 years ago
Iis it okay if we can add a 470uf capacitor or a 2220uf Capacitor ? I currently don't have the 100uf one.
Thank you.
Answer 3 years ago
you can add four 470uf in series.

Dimmeble 2 channels led with arduino and ir remote
Question 4 years ago
I don't understand anything from your schematic, I can't read it, how do I make? I don't know the polarity of the capacitor .
:(

Hi, what is the purpose of resistor R1 and R2? Especially R2. It seems R1 is used to limit current, but correct me if I am wrong

Hi,how would i do this with ws2812b leds,i understand its not as simple?? Great project Dude

Thank you Scott! Awesome project, useful guide as well! Had to use a 38KHz variant of the IR receiver because it's the one that they had at the local store (TSOP343338), and the reception works flawlessly with my One For All XSight Plus TV remote. Nice project as always :) and thank you again

Awesome project Great Scott! But can someone help me, I have made all the connections and resistors. But my LED strip is only switching on and off. Even if i let the brightness step for step increase, aftersome time it is switching on and not getting brighter. The only difference is, I used IRFZ44N MOSFETs. Does someone know what the reason could be? Thank you in advance!

After one day of bugtesting i still dont have any idea. I can give you my results.
The Blue LED is actually dimming, as it is supposed to do. The other 2 Colors are on or off. In the images, you can see my schematic and measured Voltages at brightness levels from the arduino. If anyone has a clue why green and red are not getting darker/brighter let me know please.

Buy a prototyping board first,there is no pride taken in this project!!Great Scott has set such wonderful standards,you use a cardboard?

Okay I'm blind. Only pins
3, 5, 6, 9, 10, and 11
support PWM

You obviously using an Arduino nano which now is blown due to incorrect wiring .

could you please explain me what is the capacitor for in this circuit?
Reply 6 years ago
Would it kill You to just use it.The video gives detailed information on why you need the capacitor.I watched video 10 times plus,and got it working with one go.

i made it, but cant post image, so yea.
