Red + Green dual color LED Module for 5v Microcontrollers
This module is a simple board that has a dual color LED onboard. The two colors that are available are green and red. When voltage is applied to one extremity and ground is from the center it will light up RED. When the user changes to the other extremity but keeps the center as ground it will change to Green. This neat little device makes it easier for users to program states to inform users the condition of the battery charge without having to integrate two individual LEDs.
To wire this module, simply hold the board with the pin facing towards you. The left most pin labelled – represent ground. The middle pin is input as well as the right most pin labelled S. Connect the first signal pin to pin digital 11 on Arduino and the second signal pin to digital 10.
Specifications:
- Color: Red + Green
