Explore reading analog signals with the Circuit Playground.
In this guide we will use our Circuit Playground along with a potentiometer and some alligator clips to explore how we can read analog signals into our digital computer.
No soldering required!
From the tutorial:
So how do we get those nice analog values into our digital computer so we can do cool things with the information? Simple – just use an Analog to Digital Converter (ADC). There’s all kinds of technical mumbo jumbo for how an ADC works, but for this guide it’s good enough to just think of an ADC as a device where an analog signal goes in and a digital (1s and 0s) signal comes out.
