Arduino : Analog - Calibration

Description

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 minimum and maximum initial values may seem backwards. Initially, you set the minimum high and listen for anything lower, saving it as the new minimum. Likewise, you set the maximum low and listen for anything higher as the new maximum.

Arduino : Digital - State Change Detection

Description

Often, you don't need to know the state of a digital input all the time, but you just need to know when the input changes from one state to another. For example, you want to know when a button goes from OFF to ON.  This is called state change detection, or edge detection.
