In this article, our author Mithun has developed a 0 – 99 min counter using PIC microcontroller 16F628A. So basically this is a digital count down timer ideal for engineering and diploma students for their project requirements. We have given complete circuit diagram of the digital count down timer along with full source code. In […]

Around June of 2012, I had gotten myself into a very bad habit. Instead of carrying my SD card in my camera, I left it sticking out of the side of my laptop, presumably intending to do something with the photos on it eventually. On my flight home from Boston, the predictable thing happened: as […]

This could form the basis where high performance is not required This article focuses on a minimal resource microcontroller implementation for a 3 phase BLDC motor, closed loop speed motor controller application based on a Microchip PIC12 device. It shows how minimisation techniques can reduce the number of I/O pins to just 6 for this […]

This PIC16F877A microcontroller tutorial answers the question, ” How to use timer0 of PIC16F877A and how to handle its interrupts? ” Using PIC16 simulator (Proteus) you can verify this PIC timer0 code and change it according to your needs. This code is written in C language using MPLAB with HI-TECH C compiler. You can download this […]

A Real Time clock (Digital Clock) can be made easily by using Timer 1 of a PIC Microcontroller. The Timer1 module exists in most of the series of PIC, this module can be used to easily implement a real-time clock. Instead of an external real-time clock device like a DS1307, an inexpensive 32.768 kHz watch crystal and […]

In this tutorial, I will show how to interface an xbee module with PIC microcontroller.Here MikroC Pro for PIC compiler is used to write the code. Xbee modules communicates with host devices using serial communication.Most of the PIC microcontroller have UART module to support serial communication. First of all we have to understand the two […]

After writing quite a bit of experimental tutorials on PIC16F series of microcontrollers, I thought of moving forward to the enhanced-range family of PIC microcontrollers, the PIC18F, which was introduced by Microchip in late 90s. Although PIC16F series are excellent general purpose microcontrollers, certain limitations have emerged, such as, they have limited program and data […]

A tutorial on the 12F675 PIC microcontroller which shows you how to program and use it with a series of projects starting out with a simple LED flasher and progressing on to more advanced projects.To use the tutorial files you need to have a PIC programmer with an ICSP output connector and the components shown in […]

Digital timer switches are used to control the operation of electrical devices based on a programmed schedule. This project describes a programmable digital timer based on the PIC16F628A microcontroller that can be programmed to schedule the on and off operation of an electrical appliance. The appliance is controlled through a relay switch. This timer switch […]
