PIC LICK-1 using PIC16F84 Microcontroller

This module is so simple, I'm surprised it has not been thought of before. You can fit a PIC16F84A or PIC16F628 and it becomes a "buffered PIC chip." Look at the circuit diagram first to see what the module is doing. It's buffering 5 of the input lines with a 1k resistor and buffering 8 output with a driver (actually a sinking) transistor. If you fit a PIC16F628 chip, you can use the RC oscillator inside th ...
