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.
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.
