What you will need:
1. Basic Stamp (I am using the Basic Stamp Homework Board in this example, but most should work)
2. Diode (Any regular old cheap diode should work. I'm using a 1N4148 which can be easily obtained at Radio Shack
3. (Optional, but recommended) Piezoelectric Speaker (Comes with Basic Stamp in most cases)
Let's get started!
Step 1: Connect The Parts
2. Plug a Speaker into Pin 1, and connect a wire from the other end of the speaker to Vss as well.
You're done! Now time to program the chip.
