You will need the following
- 1 yard brown fabric (we used fleece)
- Construction paper (for supporting the hat brim, can substitute with other material)
- Arduino board
- Breadboard or perfboard
- 2 9V batteries
- 1 push button
- 0 RGB LEDs
- 20 330 ohm resistors (dependent on your LEDs)
- 10 360 ohm resistors (dependent on your LEDs)
- 3 PNP transistors
- 3 NPN transistors
- 3 3K ohm resistors (dependent on your transistors)
- 3 22K ohm resistors (dependent on your transistors)
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
