Inside an RGB LED are three smaller LEDs – a red, green, and blue. All these LEDs is linked to a tab that is sew the Tri-Color LED, and are all connected through a typical anode (good) pin. Unlike other RGB LEDs, this setup implies that to light within the LED you will need to ground the person red, green, and blue LEDs rather than giving them energy.
LilyPad Arduino Simple Board
All the specific panels regarding the ProtoSnap LilyPad developing Board are simple and easy; they have one component that is big and possibly a couple of tiny supporting elements, like resistors.
Features:
- 5 Digital I/O pins
- 4 Analog pins
- ATmega328P
- Integrated LED on pin 13
- Integrated ON/OFF switch
- Built-in energy supply socket (JST connector) for the 3.7V LiPo battery and charging you circuit ( no extra battery charger required)
- Simplified design with less pins, offering more area for sewing or less projects that are complex
