I've been reading the forums for a while and learnt a lot although some of the threads are quite old.
I'm looking to use an Ardunio to drive 1 or more RGBW high power LEDs (700ma each). Now i don't believe i can drive them direct from the ardunio, and i want constant current sources so i am looking for a companion driver and then to use the ardunio to control that (eventually i want to do this wirelessly). I need dimming of each channel (RGBW).
What is the current state of driver recommendations?
What frequency would the PMW dimming be running at? It needs to be high enough to avoid flicker on video cameras (which i believe to be a problem in some cases).
I've not built anything yet, i have a mountain of learning in front of me, so i'm hoping for some guidance as to which route to take up the mountain! I'm not an electronics guy although development is no problem.
Do people take a prototype done via ardunio and go into small scale production with the same electronics?
many thanks in advance paul
