I am new to this site, but have played with machines and computers for awhile... I have accumulated a vast hoard of old and fuctional computers. I am very interested in using them to control other stuff. Robotics is to narrow a definition. Why not put my outside lightes on a circuit and put it under the control of a computer? Don't get me wrong I AM very interested in robots.
So I guess what I am asking is:
1) does anyone know how to feed an input into a computer... If so the more info the better. I was hoping that there would be a way to hook up a multiplexer to an input ( somewhere)
2) Does anyone know how to get an output out of a computer... If you can only send in input, it would be limited; would it not?
Any information that you can provide, or sources of info are welcome.
Thank you for your time any trouble.
