California JOS 50 PCS Colorful 5mm LED Light Diodes, LED Circuit Assorted Kit for Science Project Experiment (10pieces/Color)

Works well with Arduino. Shorter leg to ground. I hooked a Green to the 5v and the LED exploded immediately. Arduino is fine but overvoltage not recommended. The 3.3v works fine.

A good selection for small projects. All appears to be quality at a very good price. Exactly what I needed

Works well. They display the different wattage for each color. It helps with calculating the resistors. They work. Good product. 👍

Perfect for my project...indicating preset state on an amp modeler with bright LEDs *** The project uses four of these BRIGHT LEDs to shows selection and state of four guitar amp channels (green=clean/blue=slight distortion/red=heavy distortion/yellow=set controls for heart of the sun). Each channel can have four customizations implemented in code, represented by LED patterns solid, slow flash, fast flash, and dit/dah (short flash followed by long flash). My build uses an esp32 to bridge a mvave chocolate plus four stomp switch controller to a spark go modeler.

Good quality LEDS, however the green LED lit up yellow which was disappointing, however they are all good quality, light up pretty well and look good overall

Defective, I tested a handful only one worked and very dim. Didnt want to waste time testing all of them. It'll be wate of money if half of them doesnt work but not paying half the price.

Great product for hobbyists small projects. Great price fast delivery. Quality is good. Recommend it Recommend them.
