I'm very new to the arduino. I want to control 6 Led Strips ( Guangtek GT-SN-12W30D-5008 ) I want them to be something like dimmable, si I'm thinking in using the PWN Digital IN in an Ardunio Duelimilanove, but I don't know how to connect them to the arduino since the strips uses a 12V source energy. I have been looking through the forums and I found that I could use a ULN2003 chip. But I'm not so sure on how to make the circuit.
So I made a little schematic for your consideration :).
maybe posting this question in hardware/troubleshooting wouild yield a answer. the developement subsection is about the arduino itself, not what is connected to it.
Macsimski, I'm so sorry about the thread location, is there a way to move it to a different subforum?
Grumpy_mike, the led strip is 12V and it has 300 leds, so I'm cutting each 50 leds in order to get 6 strips. I'm going to check the links, hoping I can undestand a bit ;D
