Attach the Circuit Playground Express to the Crickit following this guide.
- Plug in the DC motor to
motor input 1on CRICKIT with the
red 5Vlead going in the outer input of the motor terminal block. Use a small screwdriver to screw in the leads into the terminal blocks.
- Attach an alligator clip to a
3.3Voutput from the CPX to one leg of the
470 ohmresistor. Then attach the other leg of the resistor to a new alligator clip. Connect the new alligator clip to the positive (the longer) lead of the white LED. Lastly attach one more alligator clip from the negative lead of the LED to
GNDon the CPX.*
- Attach an alligator clip to capacitive touch
input A3on the CPX (Circuit Playground Express). Attach the other end to some tin foil.
- For power use a 5V 2A (2000mA) switching power supply plugged into the
5V DC jack.
