CONCLUSION
Process control refers to the control of one or more system parameters. Typically, some
form of input is used to adjust this process. A simple process, such as controlling
temperature, may be performed in multiple ways. The control and complexity of the
system is based on need. For process control the BASIC Stamp is ideally suited for many
systems.
Flowcharts are a visual representation of a program or a process.
represents the necessary steps to perform the desired actions. Through the use of
symbols the actions of the program or process are graphically depicted. With knowledge
of PBASIC, the programming language of the BASIC Stamp, the process represented by
the flowchart may be programmed into the BASIC Stamp.
Means to control output devices include using the
