The 3mm Cycling RGB LED from Sparkfun is a fast-changing variety. It fades and cycles rapidly through several colors, then flashes through several more before restarting the cycle. This quick color transition feature makes it an exciting choice for those who want to create eye-catching light effects with minimal effort.
These LEDs are not just about functionality; they also bring a festive touch to any setting. They serve as excellent decorations, can be used in LED "throwies", or as indicator lights. Their bright, color-changing feature makes them a fun addition to any project or event.
