Audience Opinion Meter (AN-1)

ADB I/O can be used to get user input from remotely placed keypads to the Mac. This can be used in behavioural experimentation, audience opinion measurements and elections in classroom setups but also in other applications like entry control of rooms in combination with electric door locks.

Example: 20 people sitting in a room could each have a keypad with three buttons. Each button would return a value that would let these 20 people "vote" on how they feel about something that they are watching (e.g. a TV show, a lawyer, a commercial, etc.).

Connecting LEDs to the ADB I/O (AN-2)

The following notes are for those of you who are a bit inexperienced with hardware components. This introduction will show how simple it is to connect a hardware component to interface with the ADB I/O. The first one will explain how to hook up LEDs to the ADB I/O.

Control ADB I/O through Telnet (AN-3)

This note will show how easy it is to control ADB I/O over the internet using Telnet.

Expanding the number of digital output (AN-4)

In certain applications there would be desirable to have more than the 8 digital output channels available on the ADB. This note shows one way you can expand the digital output.

Temperature measurement (AN-5)

Using the ADB I/O for measuring temperatures is a much sought after application. This can be used in weather stations, industrial process control or as a web page feature.

Controlling analog out (AN-6)

This note shows how it is possible to control an analog out signal from ADB I/O.

DC Motor Control (AN-8)

This note shows how to control DC motors from ADB I/O.

Stepper Motor Control (AN-9)

This application note shows how to control a small unipolar stepping motor. It is very detailed so it's suitable for education.
