Home-made PLC Computer Prototype Board SBC CPU RISC PIC16F876 Analog Digital I/O

In this video I show you a neat circuit board I made. It is a 2" x 2" programmable platform embedded in the center of a prototyping breadboard. It has a 12V battery charging circuit for power backup. RS-232 interface to PC software. Four 10-bit analog inputs, four digital inputs, four output lines, musical note generator, tune/note buffer, real-time clock with 2 alarms, data-logging EEPROM. Memory: 8Kx14-bit FLASH program, 512 bytes internal EEPROM, 512 bytes external RTC EEPROM, 64K bytes external EEPROM SPI 1Mhz.
