In this project, we’re upgrading the Halo Energy Sword (by Mattel) with lots of NeoPixel LED! We’ll tear it down and find how what’s inside. This cosplay prop only features 11 LEDs, leaving a lot to be desired. The stock lighting is underwhelming but we can easily modify it with lots of NeoPixel LEDs. In this project, we’ll tear it down and replace the LEDs with NeoPixel LED strips. We’ll wire up an Adafruit Trinket and power everything with the built in 3x AAA battery power supply.
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.
