I just discovered Fritzing ; an application for designing electronic projects and laying-out PCBs. The software is dependable, has a useful website with tutorials and project examples , and they are even starting a fabrication service in Dec 2010. Fritzing was started in August 2007 by the Interaction Design Lab at the University of Applied Sciences Potsdam, Germany.
When you launch the software you begin with a breadboard. Then you drag components from a large list on the right, choosing options for the parts. Adjusting rotation, color, and placement is all fairly intuitive. While I found working with “2.5D” perspective is a little awkward at first, you get used to it. For output, you can select between Breadboard, Schematic, and PCB views on the bottom right.
Here’s a design to accompany a previous sketch, Fading an LED with PWM and a Potentiometer

Here are a couple installation shots of You Never Close Your Eyes Anymore leading up to the AC Direct installation in New York. Everyone should be so lucky to have a retired shop teacher for a father in law!

Using a potentiometer and PWM on an Arduino to fade an LED.
/* POT to LED test -> by Owen Mundy March 11, 2010
from: http://itp.nyu.edu/physcomp/Labs/AnalogIn
—————————————————————*/
int potPin = 0 ; // Analog input pin that the potentiometer is attached to
int potValue = 0 ; // value read from the pot
int led = 9 ; // PWM pin that the LED is on. n.b. PWM 0 is on digital pin 9
void setup( ) {
// initialize serial communications at 9600 bps:
Serial.begin ( 9600 ) ;
// declare the led pin as an output:
pinMode( led, OUTPUT) ;
}
void loop( ) {
potValue = analogRead( potPin) ; // read the pot value
analogWrite( led, potValue/ 4 ) ; // PWM the LED with the pot value (divided by 4 to fit in a byte)
Serial.println ( "hello" ) ; // print the pot value back to the debugger pane
delay( 10 ) ; // wait 10 milliseconds before the next loop
}
Here is the schematic for the above project.
