solon / AnalogSelectWav.pde
Created February 7, 2011 15:07
Arduino program to divide an analog sensor into a number of discrete ranges and trigger a different WAV file when the sensor value enters one of the ranges.
// these are constants that won't change while the code is running
const int lowerBound = 0;
const int threshold1 = 350;
const int threshold2 = 700;
const int upperBound = 1024;
// these variables will change
int sensorValue = 0;
int lastRange = 0;

* This code, which assumes you're using the official Arduino Ethernet shield,
* updates a Pachube feed with your analog-in values and grabs values from a Pachube
* feed - basically it enables you to have both "local" and "remote" sensors.
