Computer controlled switches
We have built a 9-foot domed observatory on the roof of our high school to house
our 12" Meade LX200 telescope. We can control the telescope from the classroom
via standard software, VNC and the school network. We need to be able to automate
control of the position of the dome. We intend to use an inexpensive barcode
reader for indexing the dome position, and I have written a program that converts
the date, time, obervatory location and Right Ascension and Declination of a
celestial target to the required azimuth for the dome slit. The thing that is
missing is a way to switch the motor on and off, forward and reverse, high speed
(12v) and low speed (6v). I am sure that I can do this with Euphoria, but I don't
know how to interface the program to physical switches or relays. Can someone
point me to the required information? We do not really need a fancy GUI. DOS
level would work if that is an advantage. Can we use Euphoria tasking to have the
dome control program interrupt the telescope software program once a second to
get current telescope position?
