CircuitPython Analog In

This quick-start example shows how you can read the analog voltage of a potentiometer connected to the Circuit

Playground Express.

First, connect your potentiometer to the Circuit Playground Express using three alligator clip leads, as shown. The

connections are:

Left pot connection to 3.3V

Center pot (wiper) to A1

Right pot connection to GND

Copy and paste the code block into code.py using your favorite text editor, and save the file, to run the demo.

When you turn the knob of the potentiometer, the wiper rotates left and right, increasing or decreasing the

resistance. This, in turn, changes the analog voltage level that will be read by the Circuit Playground Express

on A1.
