ACTIVITY #4: FIRST PROGRAM
The first program you will write and test will tell the BASIC Stamp to send a message to
your PC or laptop. Figure 1-33 shows how it sends a stream of ones and zeros to
communicate the text characters displayed by the PC or laptop. These ones and zeros are
called binary numbers. The BASIC Stamp Editor software has the ability to detect and
display these messages as you will soon see.
First Program
The program listings that you will type into the BASIC Stamp Editor and download to
the BASIC Stamp module will always be shown with a gray background like this:
Example Program: FirstProgram.bs2
' What's a Microcontroller - FirstProgram.bs2
' BASIC Stamp sends message to Debug Terminal.
' {$STAMP BS2}
' {$PBASIC 2.5}
DEBUG "Hello, it's me, your BASIC Stamp!"
