Microcontroller Based Ambinent Led Lighting

Abstract

Efficient room lighting was always a real challenge especially in these modern times where energy efficient solutions are always more than welcome. On the other hand LED technology was always on the most economical and efficient way of providing lighting. The main problem we always face with LED is that in order to properly generate the right ambient colour we need the right combination on the R/G/B based LED system. Usually, given such a task, a preferable choice is a microcontroller. However, programming such a system is always a challenge. In this paper we will show how a modern Atmel microcontroller combines with the opensource Arduino platform. We will present how using little supporting electronics a PWM based RGB LED light system can be built.
