The markings on the Stamp board I/O pins are a little confusing. Hold the board with the words “BASIC Stamp” at the top and “PARALLAX” at the bottom. Now look at the I/O pins. The top pin marked “Vin” is the plus side of the 9V battery. The next two pins are +5 volts. The next eight pins are the eight I/O ports; for these the labels line up. The bottom three pins are all ground and it doesn’t matter which you connect to.
