How can I do I/O on the Apple ][?

For switching a relay and/or sensing digital input there were severalcards. Sometimes to be found on eBay. For analog input you have twochannels in the paddles/joystick input, if you need more channels ordifferent voltage etc. you need a card.

It was also typical to buy a card with no components and build your ownI/O on that.

It was easy to use the Apple II to do I/O. Nowadays it is probably mucheasier to use a pic or cop microcontrollers (as well as many othermicrocontroller). There are inexpensive kits and you can get compilersand downloading software for free...
