Saving Data using EEPROM in PIC16F877A In this tutorial we will learn how easy it is to save data using the EEPROM present in the PIC16F877A Microcontroller. In most real time projects we might have to save some data which should not be erased even when the power is turned off. This might sound like […]

How to Use Interrupts in PIC16F877A Microcontroller In this tutorial we will learn how to use an External Interrupt in PIC Microcontroller and why/where we will need them. This is a part of the sequence of PIC Tutorials in which we started learning PIC Microcontrollers from scratch; hence this tutorial assumes that you are familiar […]

4D Systems, the manufacturer of intelligent graphics solutions, has announced a new 3.2” smart display module as part of the ‘ gen4 ’ series, which had been designed specifically for ease of integration and use, with careful consideration for space requirements and functionality. These modules features a 3.2” color TFT display with options for Cover Lens Bezel […]

GSM Interfacing with PIC Microcontroller PIC16F877A – Make and Receive Calls GSM modules are fascinating to use especially when our project requires remote access. These modules could make all actions that our normal mobile phone could do, like making/receiving a call, sending/receiving a SMS, connecting to internet using GPRS etc. You can also connect a […]

Obstacle Avoiding Robot using PIC Microcontroller Obstacle Avoider Robot is another famous robot which spices up embedded projects. For those who are new Obstacle avoider robot, it is just a normal wheeled robot which could navigate its way without hitting on any obstacles. There are many way to build a Obstacle avoider robot in project […]

The schematic forms the building block of every electrical circuit, and even if you aren’t designing one yourself, knowing how to read one is invaluable. And with some schematic reading knowledge in hand, you’ll be able to design, build and ultimately troubleshoot your way through your design logic before heading on to your PCB layout. […]

A Line Follower Robot is a simple yet fascinating robot for most students/hobbyists to build. In this tutorial we will learn How a Line Follower Robot Works and how we can build one using the PIC Microcontroller PIC16F877A. PIC16F877A is a 40-pin Multipurpose MCU from Microchip, we have used this IC in our complete PIC […]

CTRL the robot is a desktop-sized robot arm that can do a lot! It enables your computer to perform manipulation of real objects via software and gives you access to technology that has been locked away in large corporations factories. CTRL was launched on a Kickstarter campaign that unfortunately didn’t reach its goal of AU$ 215,000. The […]

Our efforts in this project were to create a version of a Microchip mid-range PIC microcontroller in verilog to run on an Altera DE2 board.  It was primarily planned to create a machine that would follow a set of pre-determined instructions and perform computation, interpretation, and control of input and output ports.  In order to […]

A computer’s arithmetic-logic unit (ALU) is the heart of the processor, performing arithmetic and logic operations on data. If you’ve studied digital logic, you’ve probably learned how to combine simple binary adder circuits to build an ALU. However, the 8008’s ALU uses clever logic circuits that can perform multiple operations efficiently. And unlike most 1970’s microprocessors, the […]
