Hey all, this is my first time on the forums. I’ve had an Arduino for a pretty short time, and I’ve been messing around with PWM control of LED’s, control over DMX, etc.
The next project I’m looking to mess with is creating a basic model for a pixel driver using the WS2811 three-channel PWM IC. I’m interested in the pixel strings places like Adafruit carry, but I’m looking at being able to control much larger pixels than what I’m seeing (upwards of dozens of RGB LEDs). To that end I’m looking at having a WS2811 IC driving three beefy MOSFETS via optocouplers, that way I can attach the driver to any sized pixel I would want to. I was hoping to throw up my basic schematic and see if anyone sees anything that’s going to cause an explosion before I construct my first test (parts are currently on order).
Eventually I’d step up to a 24V supply, and power to the pixel would go direct, not via the driver board.
Thanks for any advice
