Picture of Control anything remotely with Infrared signals.

Who would have thought that just about every Arduino attachment can be controlled in some way with a TV remote? Now its time to find out how.

Step 1: Setup and Materials

Picture of Setup and Materials
The setup for this is quite basic. The real challenge is finding neat products for this and writing the code.

1x Arduino
1x Servo available @ Hobbyking Sparkfun etc.
Jumper wires
1x Infrared receiver diode available @ Sparkfun Allelectronics Radioshack etc.
4x AA Battery and holder Ebay is the cheapest for the holder
1x TV remote

Anything that you want to control

See the attached sketchup for the setup. If you do not have sketchup you can download it here.

Good Tutorial Man! (Y)

I made something alike using an old TV remote to control several LED lights completely. Playing with Remotes and Signals is really AWESOME! \\m//



I have a great idea to use this for a school project

For the project we have to make a small wooden truck

i am making a rocket transporter

I had the idea of making the rocket move upand down at an angle

Ill try and add images when im done

Thanks for the guide though!!!

I am trying to control a owi robotic arm via a IR remote. I have got the arm to move but as soon as my remote starts sending the FFFFFFFF repeat signal my sketch doesn't recognise it and the motor stops. What is the best way to interpret this signal into my sketch?

hey, thanks for your tutorial .
But i m facing one major problem i.e.
when i fetch the IR code with help of SM0038 in fluorescent lamp light it fetch wrong code. without light it works correctly .
Please help me .......

I finally figured it out but it is only picking up zeroes no matter what button I push on a multitude of remotes.
Hammock Boy (author)  go4th5572 years ago
It sounds like you are using it as a button. What pin do you have it attached to? Perhaps try of the PWM pins such as 10 or 11. When you downloaded the library and dropped it into the Arduino folder on your computer there should be a file inside called IRremoteInt.h Inside of that is where you change Wprogram.h to Arduino.h

Can you send me a screen shot of your program with any of the error messages? Sorry this is causing you so much trouble.
Dear Hammock
I have small issue with controlling servo with remote and will really appreaciate for your help.
I have implemented IRremote to control hobby king Digital Servo motor.Problem I am facing is that there is lot of Servo jittering. It makes sufficient noise.Did you face this problem? I am trying to maintain position of servo to 90 degree in the loop.(Without Iremote is works fine) Can you please let me know whether do you have any solution to elimiate Servo motor jittering?

Thank you in advance.
I downloaded the library and put it into the Arduino library folder. I copied your code into a sketch and when i tried to upload it i get a < 'IRrecv' does not name a type > error when compiling. I'm not sure what this means ( still pretty new to the Arduino / C++ platform.

I had this exact same problem and spent way to much time trying to fix it. Fortunately there is any easy fix. Open up the Infrared library and change

in IRRemoteInt.h.

Please let me know if that doesn't work.
Hammock Boy (author)  Hammock Boy3 years ago
For some reason not all of the text posted. The attached photo shows what you need to change in the Infrared library.

I did this but when i try to save it, I am given a message that says access denied. I am the Admin of my computer so I have no idea why.
Hammock Boy (author)  go4th5572 years ago
You could create a new admin account for all of your arduino projects?

opened the IRremoteInt.h in text edit and changed the code but i am still receiving the same error message when compiling. any other thoughts?
i deleted the library and re-downloaded it and then change the code again and now it seems to be working fine. thanks. this is going to be the main controls on all my robots for a while.

I can not get this program to work no matter how hard i try. I've downloaded the library and no matter what I do, it gives me multiple errors.
Hammock Boy (author)  go4th5572 years ago
Have you gone into the library and changed to . I know this gave me an hour of frustration before I changed it.
Hammock Boy (author)  Hammock Boy2 years ago
What I was typing disappeared. Anyway if you go into the library at the top you should see WProgram.h in-between greater than, less than signs. If you have not already change that to Arduino.h
Do I find this in the library going through my program files or do I change it in the program itself? I had a little difficulty understanding what you meant.
Do I have to use a ground terminal on the IR reciever? I have two IR recievers and they only have positive and negative.
Hammock Boy (author)  knexpert17002 years ago
Can you send me the link to the data sheet? It sounds like each ground will plug into an analog pin and then you will have to use the analogRead() function.
One more question. i have been trying to use this code along with code for the Arduino motor shield. the two codes by their self work fine but when put together the motor shield does not work. could there be any conflicting pins or variables that might be interfering? 
Hammock Boy (author)  invisiblelight3863 years ago
There is a list of pins that the motor shield uses at http://arduino.cc/en/Main/ArduinoMotorShieldR3

one of them is A0 it also uses A1 so try A2 and see what happens.
Hammock Boy (author)  Hammock Boy3 years ago
After reading the motor shield page again it might be better to try using pin A4.

Hello. This project is a great ideea, tough it sould de more specific since, i guess, you entered for te arduino challenge. Nvermind, i woud like to ask if you could control more than one servo with this. Thanks.
Hammock Boy (author)  coolblue3 years ago
You can control up to 12 servos on an arduino (6 on PWM and 6 on analog pins using the servo library). So if you had a remote control with 24 buttons then each servo could have two different values it would move it individually. For example if you pressed the power button on the remote then servo 1 could move to 160 degrees. Then you could press the #2 button and that same servo would move to 50 degrees. All the while the rest of the servos would remain unchanged. To do this in the code you will need 24 unsigned longs (1 for each of the 24 buttons on the remote control. Please Let me know if this is not clear or if you have any questions.

I had this idea too, but I wanted to wire it into my light switches should I could just point and turn off the light when watching a movie.
Hammock Boy (author)  Kdemon3 years ago
You could definitely do that as long as the path to the infrared receiver is not blocked by any solid objects. Great idea.
