LED Trident for The Little Mermaid #WearableWednesday

Thanks so much to Max Minkoff for sending in his neat Trident project! Check out more here.

Here’s everything, and more, you’d ever want to know about an LED trident prop I built for our local production of Disney’s The Little Mermaid.

The code was created for an Adafruit Pro Trinket 5V using DotStar LEDs, several buttons, and pressure sensors made with Velostat conductive material.

View these pages to learn more about the physical prop, the electronics, the software and the final outer touches.

Adafruit DotStar Digital LED Strip – White 60 LED – Per Meter – WHITE: Move over NeoPixels, there’s a new LED strip in town! These fancy new DotStar LED strips are a great upgrade for people who have loved and used NeoPixel strips for a few years but want something even better. DotStar LEDs use generic 2-wire SPI, so you can push data much faster than with the NeoPixel 800 KHz protocol and there’s no specific timing required. They also have much higher PWM refresh rates, so you can do Persistence-of-Vision (POV) and have less flickering, particularly at low brightness levels. Read more.

Adafruit Pro Trinket – 5V 16MHz: Trinket’s got a big sister in town – the Pro Trinket 5V! Pro Trinket combines everything you love about Trinket with the familiarity of the common core Arduino chip, the ATmega328. It’s like an Arduino Pro Mini with more pins and USB tossed in, so delicious. Read more.


Flora breadboard is Every Wednesday is Wearable Wednesday here at Adafruit! We’re bringing you the blinkiest, most fashionable, innovative, and useful wearables from around the web and in our own original projects featuring our wearable Arduino-compatible platform, FLORA.
