This tutorial will cover more advanced uses of the WS2812/NeoPixel LEDs with a PIC. For a different project (which itself is yet another nested sub-project… 😉 I was working on a variation of the mechanism I used to generate the WS2812 bitstream in Madison’s NeoClock. This new approach still uses the PWM and DSM modules as before but drives it with the PIC’s EUSART instead of the assembly-coded-bit-banged-PWM-edge-hopping contraption used in the clock.

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.
