 pdf filePIC 16F876 Tutorial Hardware
The hardware required consists of a number of small boards (built on Veroboard), which connect together via ten pin leads using Molex connectors. The first board (Main Board) carries the PIC16F628 processor and 5V regulator - the board can be fed from a simple 9V battery. Some of the later tutorials will require two processor boards, this is the reason for the second connector on PortB - the two processors will communicate with each other over a standard 9600 baud serial bus, the second board can be either powered from the first (using a four wire connection lead), or powered from it's own supply (using a three wire connection lead). The lead consists of a ground wire, RB1 to RB2, RB2 to RB1, and an optional 5V wire. RB1 and RB2 cross over so we can experiment with the built-in hardware USART as well as software serial communications.

 pdf fileMICROCONTROLLER INTERFACING CIRCUITS
What is a PIC Microcontroller? A PIC microcontroller is a single integrated circuit small enough to fit in the palm of a hand. ‘Traditional’ microprocessor circuits contain four or five separate integrated circuits - the microprocessor (CPU) itself, an EPROM program memory chip, some RAM memory and an input/output interface. With PIC microcontrollers all these functions are included within one single package, making them cost effective and easy to use. PIC microcontrollers can be used as the ‘brain’ to control a large variety of products. In order to control devices, it is necessary to interface (or ‘connect’) them to the PIC microcontroller. This section will help to enable those with limited electronics experience to successfully complete these interfacing tasks.
