an upgraded version of the bracelet I made a few months back. this one has a lot more battery life and a lot more LEDs. I think I overdid the battery capacity, but I am going to make another version anyway. But this version came out rather well. I used a Pro Trinket 3v micro-controller and one full meter of Neopixels (144/m). The code runs multiple light trails of different colors on a random pattern at 30% brightness level.
Adafruit Pro Trinket – 3V 12MHz: Trinket’s got a big sister in town – the Pro Trinket 3V! Pro Trinket combines everything you love about Trinket with the familiarity of the core Arduino chip, the ATmega328. It’s like an Arduino Pro Mini with more pins and USB tossed in. Read more.
Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
