This provides a visual reference for wiring of the components. They aren't true to scale, just meant to be used as reference. The NeoPixel strip features alligator clips that connect directly to the pads on the Circuit Playground Express.

Power Pack

The 3xAAA battery pack can supply ~4.5V which is suffice to power the Circuit Playground Express and 30 count NeoPixel strip. The battery plugs directs into the JST connector. Optionally power over 5V USB hub like computer or charger from  mobile devices.

Wired Connections

The following connections are setup for the program in MakeCode. The data input from the NeoPixel can be switched to any available pins (except for A0 but OK on A1-A7 ) on the Circuit Playground. 

  • GND from NeoPixel strip to GND on Circuit Playground Express
  • DIN from NeoPixel strip to A1 on Circuit Playground Express
  • 5V from NeoPixel strip to VOUT on Circuit Playground Express
