Adding a volume knob

In the last step, we got our little MusicMaker setup to stream live internet radio. For this step we will add a potentiometer to the breadboard and use it as a volume knob.

In your AdaBox, grab out the small blue potentiometer:

You will also need to grab the wires and the resistor that was included.

Unplug your radio and wire up your potentiometer and resistor like this:

Now go ahead and power up your little internet radio. Once the music starts playing, twisting the potentiometer should change the volume.

Next up, we will add in a power switch so you can turn your streaming radio on and off.
