I`ve been thinking of a way to make a light panel to create flats using my 120mm refractor. I have an arduino uno board with quite a few components and led`s and wondering if I can utilize this to create a light panel?. I`d like to use quite a few led`s to cover a 120mm diameter area so maybe 13 or so to get an even light and I`d also like to make it dimmable to aim for 1/2 to 1/3 full well lumination. These led`s would be behind a diffuse cover of some sort.
I`ve found some basic code but that will only control 3 led`s, is this doable with an Arduino uno board please?. I`ve also got a raspberry pi knocking about somewhere but maybe the Arduino would be easier to set up?.
Ps maybe get away with less than 13 led`s?
