WS2801 and ULN2803 to control LED RGB5050 and IKEA Dioder

Hi everyone!

I do not know if there is presentation station, whether I would introduce myself ^ ^ sorry for my english I'm french

Here, I have a rather small project known I feel it is a system ambilight. But I want after successfully completing the lighting part is to order 2 BodyShakers with a mini amp. And a fan system which Tripping along the BodyShakers (the easiest I think). End all this is for later.

I want to make the most of the electronics so just buy the components (except the arduino, the Rpi and food)

I wonder if my drawings are good or if there are errors?

PIN 3 : 5V Arduino

Thank you for your help!

You have to change LED Module - your LED connection is wrong.

In Ikea Dioder module check connection of R1,R2,R3.

And you have to pay attention that In Ikea Dioder module ws2801 output will be inverted. So you wil not got the same color from different modules.

But idea is pretty good.
