Why did I learn it?
The goal in this series of experiments is to demonstrate how a device such as the BASIC
Stamp, which processes binary data, can be used to interface with the analog world.
Binary numbers and states form the foundation for how microcontrollers,
microprocessors and an entire class of binary circuits process data.
Analog data can be effectively processed with binary numbers using the techniques in
this experiment. Learning the basics of processing binary data will help make a myriad
of electronic circuits easier to understand. This is also the foundation for how the home
computer processes data. Understanding data at the binary level ("bit crunching") also
makes various programming languages easier to understand.
How can I apply this?
In some of the upcoming experiments, we will process analog data using serial and
parallel data. We will also use synchronous and asynchronous communication. The
BASIC Stamp can be connected to other integrated circuits and exchange binary data.
The BASIC Stamp can also be programmed to convert the binary data to a meaningful
decimal form.
We'll use these techniques to measure voltage, sound, light, etc.
The BASIC Stamp has commands which automate the serial data transmit and receive
processes in both asynchronous and synchronous modes. We will encounter the serial,
synchronous method in Chapter #3. The BASIC Stamp also has features available to
simplify the sending and receiving of parallel data, as we'll discover in Chapter #4 where
asynchronous parallel data is transmitted.
