PIC microcontrollers ( Programmable Interface Controllers), are electronic circuits that can be programmed to carry out a vast range of tasks. They can be programmed to be timers or to control a production line and much more. They are found in most electronic devices such as alarm systems, computer control systems, phones, in fact almost any electronic device. Many types of PIC microcontrollers exist, although the best are probably found in the GENIE range of programmable microcontrollers. These are programmed and simulated by Circuit Wizard software.
PIC Microcontrollers are relatively cheap and can be bought as pre-built circuits or as kits that can be assembled by the user.
The Intel 8XXX is a single-chip control-oriented microcontroller which is fabricated on Intel's reliable CHMOS III-E technology. Being a member of the MCS 51 family of controllers, the 8XXX uses the same powerful instruction set, has the same architecture, and is pin-for-pin compatible with the existing MCS 51 family of products.
The added features make it an even more powerful microcontroller for applications that require clock output, and up/down counting capabilities such as motor control. It also has a more versatile serial channel that facilitates multiprocessor communications.
