Dim an LED with DMX and Arduino Answered
I need to control a single LED strip from a DMX lighting desk. I'm planning on using an Arduino with a MOSFET and use the analogWrite function to control the brightness (possibly with some capacitors to smooth the dimming process). I want to be able to transfer the 8-bit value from the DMX channel to the 8-bit analogWrite Arduino function.
Any tips greatly appreciated as I've struggled to find any tutorials dealing with only one channel and an issue as simple as this.
UPDATE: I eventually just used an RGB LED strip DMX decoder and used the three different channels for three different LED strips.

If I figure a way of doing this with an Arduio, I'll post it here.
