IR sensor
The IR sensor fades the LED’s in and out and changes the frequency sent to the speaker.

Myriam – IR sensor
I used the IR sensor to control 2 Leds. The first one fades in from 0 to 150 and the other one from 150 to 255.
A switch turns the arduino on and off.You can view the code here.http://vimeo.com/moogaloop.swf?clip_id=3932636&server=vimeo.com&show_title=1&show_byline=1&show_portrait=0&color=&fullscreen=1

http://vimeo.com/moogaloop.swf?clip_id=4123275&server=vimeo.com&show_title=1&show_byline=1&show_portrait=0&color=c9ff23&fullscreen=1The closer an objects is to the IR sensor the higher the values coming from the IR. These values are mapped to 0-255 values of the PWM of the LED.

tricolor LED blink and fade controlled by potentiometer
BLUE/GREEN blink interval speed + RED fade in/out are controlled by one potentiometer.
when the pot is closer to a value of 0, the blinking is very fast, and there is no red to be seen or mixed in. as the pot val increases, the blink slows down, and you see red getting mixed in, until the blink is at it's slowest, and nearly disappears because all you see is red.
code is HERE

Using a POT to control 2 LED’s and a speaker
The POT fades the blue LED in and out,
increases/decreases the blinking speed of the green LED and changes the
speed and frequency of the sound on the speaker. -

Potentiometer Homework – March 27th
This project board controls the fading speed and frequency of the green LED (PWM 11) and the blinking speed of the blue LED (pin 13) though the potentiometer.

LEDs with IR Sensor
Here’s my LEDs with an IR sensor plugged in, showing both the proximity and the reading using 8 LEDs in a line as well as a fading PWM LED.

::two pots control PWM of one LED and the pulse rate of the other:::
One potentiometer controls the speed of blinking of the red LED which connected to a digital out in the Arduino. The other potentiometer controls the PWM of the white LED.

Breadboarding an Arduino • Luminosphere on Etsy.com
Posted my original prototype on Etsy. here's the link:
Luminosphere for Sale – WAY OVERPRICED
I think we all should put our stuff on Etsy!
__________________________________________________________________
I also wanted to share this link:
Maybe ITP was the place for me?
If you weren't aware, the brain of the Arduino is just an ATMega168 microcontroller which is sitting in a cradle in the middle of the board. You can pretty easily pop that guy out, and replace it with another identical chip. Now, the chip DOES have a "bootloader" on it, a small program that allows it to communicate so seamlessly with the Arduino environment.
Here is why this is so exciting- SparkFun sells the ATMega168 WITH the arduino bootloader already burned, for just $4.95 …. i hope you can see how awesome this is, I am going to be able to bring my $42 Luminosphere down to just $12 with that guy! You do, however need a 16MHz external crystal (clock) and 2 capacitors, a resistor, as well as a 7805 voltage regulator… so maybe more like $15. But still extremely worth it. Hope someone finds that useful. I just ordered a few ATMegas and crystals, if anyone wants to try this out.

Cornelius Hoot Undergoes Further User Testing
I sent Cornelius out to play and got some excellent feedback. I think the general consensus is that he is a good comfort object; he is cute, has good weight, and he invites play. However, he still needs a bit more personality. He needs to do more, he needs to have convey clear use for his buttons/switches. Apparently, hipster moms would be all over this (?), but I do have a few requests for final manufacture of Cornelius, if that time ever comes.
