Re: Controlling Valves/Relays from PC

Walden H. Leverich skrev:
All,


I'm looking to do a pet-project where I want to control the flow of
water via a PC. I need fast on/off, and I need to control ~200 different
valves. We're trying to produce something like
http://www.youtube.com/watch?v=Z2LUz2WVcek for a prom. Any ideas on a
device capable of the control? I have no problem doing the programming,
but I need something that will give me the ability to control that many
devices.
I saw recently a recommendation of http://www.i2cchip.com/ which sells a device that provides an interface from a computer to I2C (which apparently is a very common standard in electronics).

As I understood it this should easily be able to handle at least 24 switches.

I intend to look at it myself this winter :)
