Hopefully I'm asking the right question in the Title. I'm a beginner with electronics, so I maybe could state it better.
Here's the more detailed explanation:
I have an LED driver that has two wires marked PWM + and -. The manufacturer suggests 0-10V. I'd like to control the LED driver with my Raspberry Pi, which, as I understand it, can send a hardware PWM signal from 0-3.3V.
So my question is: what's the best way to do this? Someone on the RPi forums suggested I use an opto-isolator to isolate the circuits. Can anyone concur with this, or have other suggestions?
I think at this point, just buying an IC opto-isolator (if that's the best solutions) that I can plug into the RPi on one side, and the driver on the other would be ideal. Does anyone know where I might find something like this that fits the bill?
thanks in advance for any tips/help.
