/* Kissing Frog Force Input for Prince Creation mildy adapted by Hazel Onsrud
* after:
* one pot fades one led
* modified version of AnalogInput
* by DojoDave <http://www.0j0.org>
* http://www.arduino.cc/en/Tutorial/AnalogInput
*/
int potPin = 2; // select the input pin for the potentiometer
int ledPin = 9; // select the pin for the LED
int val = 0; // variable to store the value coming from the sensor
void setup() {
Serial.begin(9600);
pinMode(ledPin, OUTPUT); // declare the ledPin as an OUTPUT
}
void loop() {
val = analogRead(potPin); // read the value from the sensor, between 0 - 1024
Serial.println(val);
analogWrite(ledPin, val/4); // analogWrite can be between 0-255
delay(200);
}
Processing Code:
* I adapted the code to take serial imputs, as well as
* incorporating my mechanical FSR.
* This code notes how forceful a kiss the frog recieves and if forcefull
* enough the frog turns into a prince!
*
* (Modeled after Arduino Ball Paint which was after (Arduino Ball, modified))
* Draw balls randomly on the screen, size controlled by a device
* on a serial port. Press space bar to clear screen, or any
* other key to generate fixed-size random balls.
* Created 25 October 2006
