Probably the most important foundation for a colorful craft project: color-changing LEDs!The RGBs change color slowly and independently from red to green, blue violet, white, yellow and green. And all without programming. The color transition is very slow, which leads to a nice effect.The LEDs run on 3V. One CR2032 battery is enough. If you want to run more LEDs, two AA batteries in series are very good.Some example ideas can be seen in the gallery. The pictures are to be seen as a "serving suggestion". You buy here only one RGB LED.
