PIC Uart to PC's Serial Port Communication Circuit

This is a simple circuit for communicating PIC to PC's Serial Port

It uses a hardware UART of PIC16f628a. A level converter used is a max232 chip.

Please refer to the datasheet of both IC to check its vcc and ground pins.

Here's the schematic:

PIC based PS/2 AT Keyboard Decoder

I constructed a simple PIC based PS/2 AT Keyboard Decoder that is frequently used as an input device to different electronic projects.
