LED lighting with Arduino PWM controller
I just stumbled across this forum and your thread on your LED lighting project!
Awesome work guys!! (first post...)
I am amazed because I have been working on a similar system - so similar its scary actually!
I had someone make some circuit boards with CAT4101 chips and 5v regulators with phoenix contact screw connectors to attach to strings of 6 CREE LEDs (XPG/XPE) and a 24v power supply. I bought the LEDs already (108 ) along with my 1 foot slabs of heat sink. The idea is to put 36 LEDs (6x6 array) per slab and control 3 colours (18white/12blue/6violet) independently via PWM from an Arduino and a Chronodot.
I have all the components but haven't put it all together. You guys are way ahead of me, but nearly identical plan!
Would love to see your circuit diagram on the cat4101 to compare to mine as well, your arduino code would save me hours and hours I am sure!!
any chance at getting a peek?
Again - would love to see a pic of the finished product - I plan to document my progress as well and am fine with sharing anything I do/have in terms of hardware/code/ideas.
