Color Mixer (Update)
Last week’s assignment was "re-packaged" into the soap box. Few steps were necessary for this to work.
The LED was cut and a wire was attached to each leg:
Holes were drilled into the lid, and the sensor was glued:

Color Mixer with an IR Sensor
What a disaster! I’ve ruined one an IR sensor, and only just about managed to get this second one in action. I haven’t changed my code (yet), so I’m still using the code from the Arduino site. The code can been seen below.

Color Mixer with an IR Sensor and a tri-color LED from Joana Kelly on Vimeo.Here are some fine photos of the thing in action.
The Color Mixer
This is what my color mixer looks like from the top. The black rectangle on the right is my IR sensor. I’d like to make a nicer case for this soon.
The Innards
Here are the innards of my color mixer. It’s kind of a mess.
The Disaster
Through the simultaneous use of solder, wrapping wire, and hot glue, I finally got this working, for the most part. I do not recommend this approach. Jumper wires are definitely the way to go.

IR sensor light
What up yo!
Check out my lil IR sensor with a full-color LED (aka RGB). It didn’t have to change my code, only replace my potentiometer with my IR sensor and my 3 LEDs with the 1 full-color LED.
Sweetness.

IR Sensor Touch Lamp
Video coming soon.
Uses the same code as the earlier iteration of the hacked touch lamp.

I’ve being researching about IR Devices and reading your blog, I found your post very helpful 🙂 . I thought I would leave my first comment. I don’t know what to say except that I have enjoyed reading.

IR Proximity Color Mixer w/ Tri-Color LED
So here it is! And it works pretty well. With my setup, the long pin on the LED actually goes to power and the other three hook up to the PMW pins on the Arduino and then go to ground (I stuck some resistors in there before taking that pins to ground). Here’s what it looks like:

IR Proximity Color Mixer w/ Tri-Color LED from Katrina Bekessy on VimeoAnd here’s some pics of the box itself and its innards:
The Box
Just a little cardboard gift box I cut up to make little windows with vellum paper…I used Velcro to keep the top closed.
The Insides!
Bascially the breadboard is stacked on top of the battery pack which is on top of the Arduino. Not elegant at all…
Close up of LED
Just a closer peek at the LED setup with the resistorsI found this webpage with a great example of a tri-color LED used with the exact IR sensor we’re using. It gave code for averaging/normalizing the sensor readings so that it won’t flicker at all. I tried to use it, but I couldn’t get it to work correctly. If anyone else wants to take a stab at it, check it out: http://letsmakerobots.com/node/672
Here’s a plain text file of my Arduino code. In a different file, I used the serial commands to read the range of my sensor…The highest it went was about 620, but I wasn’t really sure what that meant or how to make that meaningful through the way it would change the colors of the LED.
