Analog to Digital

Get your Pi to read analog data

Sep 04, 2018

The Raspberry Pi still lacks analog GPIOs that would allow it to read directly from temperature and light sensors, or even humble potentiometers. With an inexpensive chip and some homegrown software you can grant the Pi the gift of analog sensing.
