It works, but I'll check it with Brock and John before recommending anyone else to use it! I used Fritzing to generate the images, very useful.

http://fritzing.org/ and fun, if you are a hopeless geek that is.

Simple Arduino code:

/*Read and print data from 2 pots and one button i.e 2 analogue, 1 digital input */
void setup(){ Serial.begin(9600);}
void loop(){
//send this data through the serial port:

Serial.print(digitalRead(7)); //button

Serial.print(","); // separate with comma

Serial.print(analogRead(0)); //pot 1

Serial.print(","); // separate with comma

Serial.print(analogRead(1)); // pot2

Serial.print(","); // separate with comma

Serial.println("");
delay(20);}
