LED Clock Using PIC (Microcontroller)

Now you can always know the exact time. With this design you can have an atomic clock in your room. Isn’t that great? Read on to know more. First of all, it is not about any radioactive elements here. This is about building a clock display that can get the time from the DCFF77 facilities […]


Microcontroller based running light controller

This project is a lights effects board using common bulbs. Description This project provides some lighting effect by the blinking pattern of the bulbs connected at its output. Up to 8 Bulbs can be connected in between connector CN2 to CN9 and AC power to control them should be connected at Connector CN10. DC Power […]


PIC Microcontroller Primer – Tutorial #1

Welcome to the starting line of the PIC Microcontroller Primer. Microchip manufacture a series of microcontrollers called PIC, and this tutorial series will take you from the basic structure of PIC µCs right through to the programming methods and techniques. Note that there are many different PIC µC packages are now available, from some basic […]


8051 Microcontroller Overview & Hardware – Tutorial #1

The intel 8051 series 8bit microcontroller, originally introduced in 1980, remains popular and has had perhaps the longest product life of all such devices. It has become the industry standard for real-time and Boolean control applications. While some (who should know better) have said that the 8051 is dead, it continues to be a viable […]


Bootload an ATmega Microcontroller & Build Your Own Arduino – 2

Since you lacked the USB interface in your own Arduino board, it becomes necessary to use a homemade/ready-made USB to Serial Converter Module as an efficient and economical solution. Inexpensive and easy-to-use USB to Serial Converter modules are now widely available, such as one shown here. With the help of this little module you can […]


Build Your Own Arduino & Bootload an ATmega Microcontroller – part 1

There are many reasons to build your own Arduino circuit on a protoboard or a custom-designed printed circuit board. At the heart of the Arduino platform is an AVR microcontroller, in usual way you need a special hardware programmer and suitable hex files to program the Atmel AVR chip. Fortunately, Arduino is a beginner-friendly platform […]


Microcontroller Bitwise Operators + #2 – Tutorial #9

This is the leftover part of Basic Bitwise Operators, prepared to draw your attention to some more learning points in connection with the Bitwise operation. In the previous tutorial, we learned all about decimal system, binary system, bitwise logic, assignment opeartors, bitshift operators, etc. So to recap: An operator is a symbol that tells the […]


Microcontroller Bitwise Operators + #1 – Tutorial #8

In this part I am going to shed some light on the background of the coding process. The first attempt is to explain the basic bitwise operators available in the C++ language. For better explanation I will express most integer values using binary notation, also known as base two (in the traditional decimal system, the […]


Microcontroller – Invention History and Story Behind the Scenes

Invention History of Microcontroller Would you believe that each one of you is using at least 20 microcontrollers in your house©©!! Well, that’s a fact. There are more than two billion microcontrollers being produced every year. Almost everybody in developed as well as developing nations cannot think of a day without using microcontrollers. The microcontroller […]
