Introduction
Piranha LED light module, is a special light module designed for easy plug and play Arduino light projects. Use this smiple, but useful, LED to light up your project!
When the LED light module is connected to Arduino, the digital pin (LOW on, HIGH off) is used to control it. The brightness of LED can be controller via PWM output.
