Old one: 16F873. Project is a Beam Antenna Rotator controller. I bought a ham antenna rotator without a control box, so I made my own. It can be joy-sticked to a new heading, or I can turn a pot to preset a desired heading, and then the rotator will run until the beam heading matches what the pot was set to. I use the LCD display to show the current beam heading in degrees (0-359), cardinal headings, N, NE, E, etc, and the preset pot value. Later I am planning to add RS232 input/output of beam heading to a PC control program. The rotator is self-calibrating if it encounters either mechanical stop.
