DiCUNO 100pcs 5mm RGB Multicolor Slow Flashing LED Diode, Multi-Color Blinking Changing Light Emitting Diodes, 2 Pins Clear Round Lens Diffused Flicker Electronic Components Circuit Lights Kit

Lots of fun for the Arduino (a ready source of 3v if nothing else.) They fade into different colors about every 4 or 5 seconds, and are nice and bright. What's not to lover?

This is one of those times the item FAR EXCEEDED expectations. I really wish my lousy video showed the colors, but for reasons I don't understand it seems to be just washed out white. Maybe they are too bright for the sensor, don't know. But these things are extremely colorful, and just a delight to watch. The speeds change, and the colors rotate satisfactorily. Although these are supposed to tolerate up to 3.4 volts (DC), I am using an 18650 battery (installed in the homemade double decker "Santa Caboose) that is charged to 4.17 volts. ( It is also running an LED light strip in the car). I tested the lights before I made the car, and they seem to tolerate the higher voltage just fine. ( I used an 18650 because of the superior power and longevity) The legs that connect to power accept solder readily, and are easy to bend to whatever configuration you need them in. I'm almost hesitant to heap too many accolades on this item, 'cause I may buy more for other projects and I don't want 'em raising prices. But heck, at $8 for 100 of these, it's was beyond a bargain ! These are just some of the best things I have ever bought, fun to build, watch, and plan projects with.

Works great. Good and bright

Bought these to fix a small fiber-optic xmas tree that had a burned-out motor. 15 of these guys at 12 mA each took care of the lighting. The color rotation seems to have only a brief red phase. The tree is mostly blue/green but hey it works.

The count is right and the item seems ok. I just got one that did not work after soldering it on but I have so many, that it does not matter. I always update my review so if I enconter another, stars will start to disappear one at a time too.

Just what I needed for a project, they ended up being almost to bright. Had to sand the surface to diffuse the light somewhat. But great otherwise.

Though I don't know what I'll do with all of these, I did use one in a wand that I made, and it really came out nicely. I found that two button cell batteries will power one, and I'm sure if I do more experiments with these, I can find more uses for them, and better ways to power them. All together this is one heck of a deal.

These little lights are amazing in any diy project they change colors and are extremely bright, the only thing that I regret is that I didnt purchase both the fast and slow switching so now I have to put in another order

Satisface mis expectativas

this product is really awesome and my son does lots of projects using this, thank you
