Tutorials with Arduino: Arduino controlled by Apple Remote (updated)

Controlling Leds by the Apple Remote (video updated using the Iphone Photostudio for Arduino Stand)

The idea originated because i´m learning a lot on Led driven home applications for lighting, and the first project i´m doing is led lighting for the kitchen (indirect). The commercial systems are very expensive, specially with dimmers and remote controls, so why not Arduino System?

The programming i thought would be very difficult for the IR remote, but it was very simple and fast thanks to this library:  IRremote that you can download from this link.

Part List:

• 3 x LED
• 3 x resistencias 220 ohm
• 1 x IR receiver transistor
• 1 x placa Arduino UNO
• 1 x Apple Remote (funciona con cualquier control IR, sólo que me gusta el apple personalmente).
• 1 x breadboard

The conexions are made following the attached schematics; in this case i used digital input 11 to receive the info from de IR receiver, and the 4, and 5 as digital outputs for the LEDS and the 9 as analog output for the dimmer LED. The only difference between the 4, 5 and 9, is that in one of the LEDS i want to control de intensity (dimmer), using more buttons from the Apple Remote.

We are using the PLay button to start the middle led, the << (rev) button for the left led and the >> (FF) button for the right led. The + and – buttons will be used to change the intensity of the middle led.

/* Code for using the Apple Remote Control on Arduino
To be used with 3 leds, port 4 and 5 (left and right), port 9 center.
The + and - buttons act as dimmers on the port 9 led.
The IR receiver is installed on port 11.
On the center led (PLAY button) yo can switch on and off with the same button.
