Computer Interface :
The PC is now an economic and common equipment at home or
office. Due to Open source
and GNU Linux, many professional
programs and environments are easily accessible. To interface it to the
real world is a step in learning Automation and Robotics.
In Automation we have both Industrial and Home. You can start with home
automation, as industrial automation is more complex. But in Home
Automation, Safety First should be emphasized, Any neglect in care of
electrical hazards will neutralize any advantage of Home
Automation.
Printer Port
Do not apply voltage above 5V to any pin of printer port, ensure
earthing is good, use opto couplers for inputs and outputs if you are
not sure. wrong use will damage motherboard, these circuits should be
used only if your basics are very sound.
