Calibration
Demonstrates one techinque for calibrating sensor input. The
Demonstrates one technique for calibrating sensor input. The
sensor readings during the first five seconds of the sketch
execution define the minimum and maximum of expected values
attached to the sensor pin.
The sensor minumum and maximum initial values may seem backwards.
The sensor minimum and maximum initial values may seem backwards.
Initially, you set the minimum high and listen for anything
lower, saving it as the new minumum. Likewise, you set the
lower, saving it as the new minimum. Likewise, you set the
maximum low and listen for anything higher as the new maximum.
