Get your cybergoth on with five color-changing NeoPixels studded onto a leather collar. The tiny GEMMA microcontroller can display endless animations on this fun funky accessory that’s easy to make with a little soldering!
You will need:
GEMMA mini Arduino-compatible microcontroller (can also substitute Trinket)
through-hole NeoPixels
leather collar or cuff
150mAh rechargeable lipoly battery and charger
solderless breadboard and alligator clips for prototyping
soldering iron and solder
solid core or stranded wire (20 to 26 gauge)
helping third hand tool
pliers
wire strippers
flush diagonal cutters
awl or other pointy tool to pierce leather
sharp utility knife
cutting mat
ruler
marking pen/pencil
gaffer tape or other material to protect battery
velcro tape to secure battery to collar
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.
