Planning to incorporate NeoPixels into portable, wearable or cosplay projects? The way NeoPixel power needs are usually estimated, you might think you’ll have to carry around a car battery or a Mr. Fusion reactor. With some foresight, it’s possible to put on an impressive display — and run it for hours — from modest power sources.
The key to making this work is to approach the problem from the other direction: not how-much-battery, but how-little-NeoPixel can you get away with? Thoughtful design in layout, color selection and animation patterns make an enormous difference in power requirements.
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.
