SatHole is a simple rotor controller that (for now) emulates gs232 protocol.
It is based on the low-cost Arduino hardware,like the nano/uno boards.
Firmware is a work in progress, for now, it has a “setup” mode, where you can set various parameters, like rotor position vs. analog sensor, emulation mode and so on.
It features a lcd display to show current rotor pos ( az/el data ).
Four ports are used to control left,right, up and down commands, and two analog ports are used to sample azimuth/elevation feedback voltage.
Recently I have retro-fitted my sliding table saw with a digital readout , but unsatisfied from the minimalist default display, i have re-designed the display unit using Arduino + lcd and button unit.
