ABSTRACT
The principal feature of microcontrollers are self-sufficiency and low cost. Microcontroller is not designed to be a data processing machine, but rather an intelligent core for a specialized dedicated system. Microcontrollers are embedded in many control, monitoring, and processing systems. All the basic circuits contain at least one microcontroller. A few microcontrollers are designed as general-purpose devices, especially the type called digital signal processors. Due to their low cost and easy availability, some microcontrollers have become very popular among amateur system designers. PIC is a family of microcontrollers made by Microchip Technology. Storing a program in a PIC microcontroller is popularly referred to as “blowing” a PIC. PIC microcontrollers are classified by Microchip into three groups: baseline, mid-range, and high-performance. Testing a program is not difficult with a development board but only if the board is compatible with the microcontroller, and if it provides the hardware that we need to test.
