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. KEYWORDS: Microprocessor, Arduino, Atmel, PWM, LED, Ambient light. I. INTRODUCTION
When we started our analysis on the task at hand we had to define some basic concepts in order to make the project more sustainable. Generally these concepts where based in two different categories: hardware and software. On the hardware side we would like the platform to be minimalist, mainly based on the least needed number of components. Additionally, the idea was to build the system from components which are easily available and known to students in order to be possible to further develop the system. On the software side we decided to try to use most common used programming languages and also if possible have some code reusage. Most microcontroller platforms are base on C or alike languages, so this was not a project stopper. When looking into the different options one platform made it really
