An RTC Module or a Real Time Clock Module helps a system keep track of current time (hour, minutes and seconds). It automatically increments the time without any help from the host (microcontroller). Other benefit is that it has a ...

In the last tutorial we learn about the multiplexing technique used with seven segment displays. We learnt how it saves i/o line by using persistence of vision. Only one digit is lit at a time, but to a human eye ...

Interrupts are common features in almost all processor family, be it old 8051, AVR, PIC, ARM or the x86 used in desktops. So their in depth and clear knowledge is required for successful system software engineers. ...

The are many cool sensors available now a days, ranging from IR distance sensor modules, accelerometers, humidity sensors, temperature sensors and many many more(gas sensors, alcohol sensor, motion sensors, touch screens). Many of these ...

Many electrical signals around us are Analog in nature. That means a quantity varies directly with some other quantity. The first quantity is mostly voltage while that second quantity can be anything like temperature, pressure, light, ...

In this tutorial I you show you how to make a very useful expansion board for our PIC development board. It will be a Do It Your self (DIY) LCD Expansion board. The expansion ...

Timers are common features of most microcontroller. In simplified terms a timer is just a register whose value keeps increasing (or decreasing) by a constant rate without the help of the CPU. The CPU can read ...

Hello Friends! In this tutorial I will discuss how to practically do a simple communication over RS232 interface. For those who are completely new to this I clarify that the motive is to send and receive ...

A large number of embedded project require some type of user interface. This includes displaying numerical, textual and graphical data to user. For very simple numerical display we can use 7 segment displays. If ...

The PIC Development board from eXtreme Electronics has the feature of connecting add-on boards, like user interface board or a motor controller board. You can also make your ...

Hello friends, welcome to this exciting tutorial were we will begin our journey with latest PIC18F micros from Microchip Technologies. This tutorial will give you information on what ...
