Hey,

iam new to the arduino community and do have some questions about a project I want to realize.

I want to control 8 RGB LEDS separately (light intensity and color). I thought doing all this in 3 development steps:

1# At the first step i want to control light density of 8 LEDs separately.

2# I want to add the opportunity to control the full RGB spectrum of RGB LEDs - that means 24 seperate channels.

3# I want to control 8 3W RGB LEDs

Which Arduinoboard is going to be sufficient for my project (until #2)? Which hardware additional hardware like resistors... do i need (until #2)?

greetz,

Hi Flo,

This is typicall done with a pwm driver chip like the TLC5940. There are a couple of breakout boards out there, if you don't want to wire it yourself (although it's available as a DIP version, too). Our own one is probably coming out soon, too!

This chip can be used for all your three steps, you just might need to add an external power source for #3.

Good luck,
andré
