I replicated a project that uses an ESP32 to control an old Meade ETX telescope with the SkyWatcher Synscan Pro app on a phone....like a year ago...barely got it working to the point of moving the scope with the app and lost my good sky viewing spot access.
I really need to get an old HP rack mounted lab power supply working at some point soon. It only has a HPIB interface and I want to control it with an arduino but am still too intimidated to try.
