ATM18 Port Expander (071035-95)
Just imagine sitting in your easy chair and using a remote control to control everything that serves your comfort and convenience: lamps, the radio, a fan, and what have you. - Have it all your own way!
Since time immemorial, people have always wanted to see the effects of their deeds and shown them to others. Among electronics hobbyists and professionals, this often takes the form of wanting to make some action inside a computer visible to the outside world.
Today we usually refer to this as ‘regulation and control’ instead of ‘having things your own way’.
Now that our ATM18 project with the levitating magnet in the last issue has become truly active, we can use a relay board to implement even more external effects.
