DigiLED RGB LED vs RGB LED shields
« on: February 27, 2016, 06:00:01 am »
Could someone explain the difference in these two shield kits?

I see that one uses 3 resistors and the other a capacitor but I don't understand what is functionally difference between these two shields:

DigiLED is based upon the WS2812B RGB Led which has an IC built in that is addressable and lets you control the RGB color via a single pin (DI). You can connect additional WS2812B RGB LEDs via DO and control each LED individually using the functions found in the Adafruit NeoPixel library for example. The capacitor is there to condition power to the LEDs IC.

The RGB Shield is a simple 3 color LED that requires 3 pins to control it's color output (one pwm pin for each color). The resistors are for current limiting.

DigiLEDs can be more fun and educational to play with. If you intend to build or play with an RGB strip of LEDs, DigiLED is a good place to start as it is scalable.

Thanks - I think I'll go with the DigiLED then.
