Force sensors

Project Members: 
Travis Pinnick

Lab involved using force sensor or photocell to control an led:



* 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(50); // rest a little...
