Reading Sensor Values
Comp Craft Spring 2013
This sketch reads the data coming in from the sensor and prints it to the serial
monitor. This is extremely helpful to debug or find the range of values you
want to use.
int sensorPin = A0; // select the input pin for the sensor
int ledPin = 9; // select the pin for the LED
int sensorValue = 0; // variable to store the value coming from the sensor
void setup() {
// declare the ledPin as an OUTPUT:
pinMode(ledPin, OUTPUT);
pinMode(sensorPin, INPUT);
void loop() {
// read the value from the sensor:
sensorValue = analogRead(sensorPin);
analogWrite(ledPin, sensorValue);
//Print the value to the Serial monitor
