Car bord computer


 


This circuit is based around the PIC 16F873 microcontroller. This chip is actually a small computer contained in a single chip, including RAM memory, EEPROM, I/O ports, CPU and so on. When you buy this chip, it comes empty with no program on it. You have to compile the source code and download the resulting machine code into it, using a PC and a small programmer attached to the parallel port of the PC and the chip. To get yourself familiar with this stuff, I suggest you first read this link: Getting started with microcontrollers.
