Program:

The BASIC Stamp is a microcontroller developed by Parallax, Inc. which is easily programmed using a form of the BASIC programming language. It is called a "Stamp" simply because it is close to the size of an average postage stamp. Since the Basic stamp is programmable using a computer the actual program sequence is up to the designer.

In the example linked to this page WACCO III is programmed to:
1. Navigate through a maze or obstacle course for 2 min.
2. Pause 2 sec.
3. Play a random tune (1 of 4).
4. Pause 2 sec.
5. Spin in tight circle for 3 sec.
6. Pause 2 min.
7. Repeat from #1.
