Attach the Circuit Playground Express to the Crickit following this guide.

Wiring up the main electronic components

  • Plug in the DC motor to motor input 1 on CRICKIT with the red 5V lead 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 3.3V output from the CPX to one leg of the 470 ohm resistor. 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 GND on the CPX.*
  • Attach an alligator clip to capacitive touch input A3 on 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.

*To learn more about why we'd need a resistor and LEDs in general check out the guide, All About LEDs.

This is the main circuit we will be using. We'll add the rest of the LEDs later.
