Keyes 5mm Bi-Colour LED Module

This module is ideally suited to adding a slightly different light display to your project. This module lets you control a bi-colour red/green LED to display your information in a bold and bright way. This opens up all manner of possibilities from model rail road signals through to emotional eyes of a robot.

Each colour of the LED is individually controlled to provide red or green depending on the higher voltage. A resistor will be required in most cases, the value of which can be found using ohms law. Voltage = Current x Resistance. We recommend starting with a 1K resistor with a 5V source on the ground pin of the module. Following which you can adjust to achieve the brightness you require.

If you require assistance using the components or finding the value of the resistor to pair it them, please do not hesitate to contact us.
