SUMMARY
This chapter introduced the technique of individually testing each circuit-subsystem
before integrating it into a larger system. This chapter also introduced the
command, which is particularly useful for menu systems. The useful
demonstrated as a way to name your I/O pins and then let the BASIC Stamp Editor figure
out whether to read an input or write to an output. A password program was used to
introduce variable arrays, the
formatter. The password program was then integrated into a larger sensor terminal
program to give it more functionality.
