Simple Visual Basic controller/scheduler

["Nick Towers" <nickt@xxxxxxx>]

I've been liaising with Ian Bird regarding controlling his relay 
board via serial link from PC - he's making good progress on a PIC 
based serial controller.

What is needed at front end is a (hopefully simple) program, ideally 
in Visual Basic, as it's standard stuff, to schedule the operation of 
the relays. Sure it cannot be rocket science to do this but may just 
as well be 'cos my programming's very limited. Does anyone out there 
know how to put something like this together?

The program would need to run 24/7 and be able to send commands at 
scheduled times eg <<at 02:00 send "ON relay 1">>,
<<at 03:30 
send "OFF relay 1">>. It will ideally need to be able to
perform 
simple control (eg if sensor says its raining, send OFF signals to 
all garden watering relays), monitor status information coming from 
serial port, maybe produce a log, alarms etc.

To start with though, something very simple would be great so that 
the system can at least be tested out. 

Can anyone help with this?
