to the tiny solder pads on NeoPixel rings. Better to solder a small pigtail wire to the ring and

attach the alligator clips to that.

Some of our NeoPixel project guides fail to mention the above precautions…they were written

before these lessons were learned, and will be updated as required. The design changes are

usually minimal (e.g. add inline resistor on data pin in circuit diagrams).

Smaller, battery-operated projects (e.g. FLORA and sewables) are usually fine omitting the

capacitor and/or the resistor, but more substantive projects incorporating NeoPixel rings, matrices

or a meter or more of NeoPixel strip, or using a plug-in power supply should definitely include both!
