I have some days off and I would like to put the antenna rotator in the backyard to move a small loop antenna. Every time I want to turn it I have to go outside, and if it is raining or late in the night it is a bit of a hassle.
The thing is that I don’t want to crawl under the house to pass the control cable, so maybe it can be done via web with a ESP2866 module.
I would be passing the DC power to move the rotator (+24 V) via the coaxial cable, and the “only” thing I need to do is to activate two relays (CW, CCW) and read an analog voltage back (the rotator has a potentiometer to read its angle).
So far I have been looking at heaps of youtube tutorials (and I have tried a few) about switching LED lights on and off and reading temperature with web browsers, but I haven’t came across an example where you can drive two relays AND read an analog voltage back.
So any hint/help is greatly appreciated. I have all the bits in the house, I can take them to the space one of these days to show what do I want to do.
