I posted this in an aquarium forum (DIY section) but could not get any help, so I am hoping to make an Arduino version.
My situation is as follows:
I have a 12V DC motor, that can run on 3V-12V, plus a DC power source (Variable 12V).
I also have an aquarium controller called the Apex Jr. from Neptune Systems - It's a computer that controls various devices, mainly by turning them off and on. There is an add-on to this device, called the VDM, which has several ports called "0-10V variable speed ports". The ports are one serial, and two Ethernet jacks (That handle two inputs each). The only thing I do know is that these ports do not send power, but signals (PWM, I believe) to regulate voltage.
Is there a way I can construct an Arduino device that can interpret these signals and provide the appropriate voltage to my DC motor?
I have some experience coding and some electrical, from way back in the day, and am willing to do/relearn it for this project. I do not, however, have any experience with Arduino)
Thanks for any help!
