Hi all, I'm trying to control a light that uses a 0-10v control signal, as I can't find much on the actual needs of the 0-10v for the light I want to try to have the signal be true 0-10v, not PWMed. Right now I have an Uno with a Sparkfun MCP4725 to convert from 0-5v PWM to 0-5v true analogue and an LM358 to take that signal to 0-10v. The MCP4725 works fine, when tested with the multimeter I get exactly what is programmed from the Uno, but I can't get the LM358 to work, I know it is wiring and or resistor choice, I've never used an op-amp before and am pretty leery about experimenting with different resistors without damaging something.
The whole shebang is powered by a Mini-360 DC-DC buck converter set to 5v, as I was worried the Uno might not have the juice to handle everything as is.
Below is the schematic I'm working from and a couple photos of how things are connected right now.
You guys have been a great help in the past!! Any help is really appreciated.
