Looking for a gadget to help an IoT project....

Post by MAScalia »

I need to be able to send a DC output (range 0-10V) out of an IoT controller or device so I can use the dimming control function on my vegetable tent grow lights.

I'm comfortable with Raspberry Pi's and ESP-32's, neither of which can natively generate such an output (that I know of).

Is there an add-on board, HAT, or some other gadget I can pair with a controller where I can tell it to "send 5.5V DC" through the output that's connected to the light?

FYI, 0V = "Light is off", and 10V = "Max Brightness".

Thanks in advance for any help.

This might work for you: https://www.adafruit.com/product/4286

It can handle up to 15.5v. You'll have to supply it with 10v on Rh and its output (Rw) will provide 0v-10v in 128 steps.

Thanks Dave! That looks exactly like what I need.

My local Microcenter doesn't have it in stock, though, so I'll have to order it from Adafruit.
