Circuit 13: Squeezing

Circuit 13CIRC13 Fritzing Diagram_bb

 * Force Sensitive Resistor Test Code
 * The intensity of the LED will vary with the amount of pressure on the sensor

int sensePin = 2;    // the pin the FSR is attached to
int ledPin = 9;      // the pin the LED is attached to (use one capable of PWM)

void setup() {
  pinMode(ledPin, OUTPUT);  // declare the ledPin as an OUTPUT

void loop() {
  int value = analogRead(sensePin) / 4; //the voltage on the pin divded by 4 (to scale from 10 bits (0-1024) to 8 (0-255)
  analogWrite(ledPin, value);        //sets the LEDs intensity proportional to the pressure on the sensor
  Serial.println(value);              //print the value to the debug window
