This post provides the external interrupt code for PIC12F675 microcontroller (e-g when you need to control servo motor which has position encoder, with your PIC microcontroller). As we know, PIC12F675 microcontroller has one GP2/INT pin, which can be used to service external interrupts. This code is written in C language using MPLAB with HI-TECH C compiler. You can download this code from the 'Downloads' se ...

Electronic code locking system is extremely useful in protecting our precious possessions and can be installed anywhere with bit of engineering in it. We are widely familiar with the Password based e-locks and might have installed in our house. But we are going for Electronic locks made by any company when you can make one by your own. This project demonstrates you how to make a PIC microcontroller based si ...

This tutorial will help you to interface DS1307 RTC with PIC16F877 Microcontroller. The project is compiled in CCS Compiler and simulated with Proteus. The Real Time Clock is interfaced with PIC controller via I2C. I2C is a 2 wire communication protocol. I2C is used for moving data from one device to another simply and quickly. It is a serial, synchronous, Bi-Directional protocol, the data is synchronised   ...
