First, attach the alligator clip leads as shown to the captivate pads on the Circuit Playground Express.
Next, arrange your fruit triggers in a circle around the board. Then, plug the lead pins into each piece of fruit.
Plug in the battery pack and then turn it on -- you want to avoid touching any fruit triggers or wires while the Circuit Playground Express is starting up -- as this is when the capacitive sense pads are calibrated.
You're ready to make music!
