Sensing and Control for hobbyists and schools- 1- Wire Actuators
The Dallas support chips for 1-Wire / MicroLan are mostly sensors and counters for tabulating inbound data. None-the-less, designers working with 1-Wire can also control actuators.
The first element in their work is the DS2405 addressable switch. With one (or more) of this device on the 1-Wire LAN, the control program can send a "turn it on" message to the outside world. One side of the DS2405 connects to the 1-Wire, the other is connected to external electronics. To those electronics, the DS2405 looks like a switch. Admittedly, it can't be used to switch very much... directly... but there are solutions to that problem. Once you can switch something on and off, it is up to you what sort of actuator you want to switch on and off!
I should just bring a note from a Dallas document to your attention. It says...
"Due to electric safety concerns in controlling high power equipment through the DS9097 COM port adapter with its floating ground.... For real applications.... a different type of MicroLan interface is absolutely required to address the safety issues."
This merely echoes my warnings elsewhere: If you don't know what you're doing, stay away from household electricity and be happy with low voltages and limited currents.

The search engine merely looks for the words you type, so....
* Spell them properly.
* Don't bother with "How do I get rich?" That will merely return pages with "how", "do", "I"....
Please also note that I have two other sites, and that this search will not include them. They have their own search buttons.
My site at Arunet.
My oldest site. (It's at Compuserve).
Ad from page's editor: Yes.. I do enjoy compiling these things for you...
hope they are helpful. However.. this doesn't pay my bills!!! If you find
this stuff useful, (and you run an MS-DOS or Windows PC) please visit my
freeware and shareware page, download something, and circulate it for me?
At least (please) send an 'I liked the parallel port use page, and I'm
from (country/ state)' email? (No... I don't do spam)
Links on your page to this page would also be appreciated!
