I'm in the middle of gathering all my materials so don't have anything running yet but I've been doing a lot of research on using wifi to dim the led drivers (this thread has helped me a lot, thanks everyone for posting all these resources.)
So from what I gathered, in order to dim the LED driver we need a 0-10v analog output controlled by an arduino (or any microcontroller).
[[ I HAVE NOT TRIED THIS YET, PROCEED AT YOUR OWN RISK]]
The arduino can only output 5v, so it would only be able to dim 0-50%.. no good! We need a voltage doubler circuit in order to output the full 10v. I lack the electrical experience to do this.. but I make up for it with research skills!
I found these modules that convert the Arduino's PWM signal to a 0-10v output so it should do exactly what we're trying to accomplish here. So the requirements would be:
- 1x Arduino Uno (can output 5v):

- 1x PWM 0-10V Digital to Analog Signal Converter:

Connect the module to the arduino, connect the DIM + DIM - to the module. Use code to drive the pwm signal (I plan to use a web interface with a slider / buttons to change the pwm signal).. magically watch the lights dim.
I'm going to order the module, but I haven't even started my grow yet so I don't want to burn my new hard-earned driver
I'll test with a multimeter and measure the voltage output first, then maybe buy a cheaper driver for a real-world test before trying it on my bigger one... but I'm definitely curious what anyone else thinks of this
