– Cardboard boxes, glue, clamps, painters tape, brown paint from Home Depot
– Trinket M0, NeoPixel 12 (x2) and 16 (x2) rings, solid hookup wires, wire connectors, illuminated latching switches from Adafruit
– Decals printed on a regular inkjet printer on regular printer paper and glued on
– I popped one of the illuminated latching switch LEDs because I assumed both switch LED’s had the same 3V forward voltage. The orange one was 2.2V.. Reminder: Always read ALL datasheets!
The code on the Trinket is very simple. Configure a 24 light strip for the blinkers (pin 0) and a 32 light strip for the headlights (pin 1). The headlights were set to be constant white and the blinkers switched between black and amber every 500ms.
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, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, 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.
