HI WORLD! Can anyone point a complete novice in the right direction??

I've an interest in learning how to write my own programme to operate electrical relays, motors etc.
I'm sure there are lots of ready made applications etc... but I would like to be able to add in some methods of controlling temperature, liquid flow etc....general mechanical & electrical control!
Maybe this is too advanced an ask, but if anyone can help I'd appreciate some help or advice....


By the way..

thanks in advance...

How do those devices connect to the computer? Do you have drivers with API doc that can communicate with the devices? Java programs would probably have to use JNI to communicate with the drivers.

While it isn't Java I use the Arduino to do some of what you're looking to do. Controlling a motor or a relay (of modest size) is very straight forward. Things like liquid flow could use a simple flow meter (that, by the way, has code for the Arduino on the site).

If you use the included programming environment the language is more like C than Java but is very easy to use.

Hi, thx for reply!
At present I have connected successfully an 8 relay USB type board to pc.
So I guess that any type of programming involving either 232 or USB really,

Cheers again mate..

Thanks for this info mate!
I'll have a wee look at this and keep you posted on how I get on..

again many thnx!
