I'm going to cut up almost the whole strip to use them seperatly.Something like:Arduino Leonardo -> IC -> 3 or 6 Led stripsDo I still need 3 NPN transistors per strip? Or can these be placed before the IC?
Which IC would fit best in here? I was thinking of the WS2803D because it's cheaper than the WS2801.Or would you recommend somethint like the 74HC595?
t and I'm going for a 12V 5M 300 RGB SMD 5050 led strip, with a 12V 2A power adapter.
I can't seem to find anything about about the high voltage option of the WS2803.
Hi Danton,I knocked up a rough schematic of what you need. It is by no means complete (I'm meant to be working at the moment). You will need to ground the 12V supply with the arduino ground, calculate the IREF resistor value and add a couple of caps to smooth things out. You could also power the arduino from the 12V supply either by adding a 5V voltage regulator connected to Vin on the arduino OR fit a suitable plug to connect to the arduino power socket.
