Using the EZIO board with simple switches.

LINGO TERMS: global EZIO -------- Call digital input line 1 in this way: D1=EZIO.readLine (1) D1 will hold boolean values only, a zero or a 1.

EXERCISES:

Before you start:

1-Download the Keyspan adapter and install. Hook up your board as demonstrated in class-plug serial cable into port 1 of the adapter. Remember to not connect power to the board until wiring and downloads are complete.

2-Test to determine which Keyspan port is being read. Use Sherlock, and find the application called Keyspan USA-28X Manager. Check to make sure the computer is reading the printer port.

3-Download Ben Chang's EZIO XTRA. Copy the XTRA, "EZIOXtra" from the download folder to the Xtras folder in the Director 8.5 application on your hard drive.

4-Download Holmes' sample movies (zip file)

2-Open and play the movie simpleswitch.dir.

Intermediate:

1-Hook up two switches and have one switch make a bitmap move left, and have another switch make a bitmap move right.

2-Add a "next" button and a marker to your movie. Create a new looping script that will play a sound or a quicktime movie each time a switch is flipped.

Advanced

BEFORE YOU BEGIN: Hook up a photocell (with a pot) to the EZIO board, line 1. (Open the movie and make sure it works with your photocell.)

Problem 1: Add a script to add a switch to the intermediate movie. Adapt the movie "a2d_sensor.dir" so that when you hit the switch, a sprite changes color.

Problem 2: Add a second A/D sensor that will control the blend of a second sprite.

Problem 3: Delete everything from the score. Create a keyframed animation that is 255 frames long. Use the reading from your A/D sensor to move the playback head to the frame in your animation that corresponds to the number being read at A/D line 1.
