Small costume project w/powerboost & neo pixel rings

by vegas78 on Wed Nov 22, 2017 12:20 am

Hi I have a costuming project that I would like to use the Neopixel rings on. It only requires white steady light- no blinking or rgb switching etc. Initially I was looking at using the Powerboost 500 with the 3.7 lipo battery, conductive thread, and a push toggle switch such as a clicky switch for flashlight (https://www.aliexpress.com/item/OMTEN-P ... 0.0.O0bovZ.) Will this work on the Neopixel rings directly from the Powerboost? Thanks in advance.

You can run NeoPixel rings from a PowerBoost, and the switch looks like it would be able to control that power, but you'll also need a microcontroller.

NeoPixels don't do anything on their own. They need a microcontroller to generate the signals that tell them what to do with their LEDs.

What you're doing sounds simple enough that a Gemma should be more than enough to handle the job though:

Awesome- thanks for the reply. So I had a friend give me one of his gemmas and I've downloaded and installed Arduino IDE and the drivers etc. Could you point me in the right direction for a sketch that would allow the neopixel rings to emit steady white light? I'm totally new to mini controllers, boards, libraries etc. Thanks again!

The best place to start would be the example sketch named ‘simple’ in the NeoPixel library:

You set the output color of a pixel with the red, green, and blue values in the function .setPixelColor().
