Alright. Fun time.
In order to create an analog signal we can control, we will connect a potentiometer to the Circuit Playground. By connecting the ends of the potentiometer to the 3.3V and GND there will be a variable voltage on the middle (sweep) pin.

This is the overall view of the hookup.

|
|
Simply connect the alligator clips to the gold pads on the edge of the Circuit Playground as shown. |
|
|
The alligator clips should clamp nicely onto the leads of the potentiometer as shown. |
|
|
With this hookup, the voltage on the yellow (OUT) will vary with knob position as shown. |
Using Breadboard Trim Pot
The test circuit can also be setup on a breadboard as shown below. You can go this route if you want, like if you already have some of these parts, but the knob on the panel mount potentiometer is bigger and easier to work with.
