Mr. Clean Does It All

Use the Arduino and FSR along with a Mr. Clean sponge half
to control a light emitting diode. Due to technical difficulties
experienced at home, I couldn't implement my original design
of an interactive cat toy and FSR (I'm uploading from school, so
no access to my cats).

Components Used

Light Emitting Diode (LED)

Arduino Code

 * Resistive Sensor Input
 * Takes the input from a resistive sensor, e.g., FSR or photocell
 * Dims the LED accordingly, and sends the value (0-255) to the serial port
int sensorPin = 0;  // select the input pin for the sensor
int ledPin = 11;    // select the output pin for the LED
int val = 0;        // variable to store the value coming from the sensor
void setup() {
void loop() {
  val = analogRead(sensorPin); // read the value from the sensor, 0-1023
  analogWrite(ledPin, val/4);  // analogWrite (dimming the LED) can be between 0-255
  Serial.println(val/4);       // writing the value to the PC via serial connection
  delay(500);                   // rest a little...
