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 are analog in nature. That means they give a voltage output that varies [...]

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, force or acceleration. For example in LM35 temperature sensor the output [...]

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 board can be plugged into the PIC development board to add 16x2 Alphanumeric [...]

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 or write this register any time. It reads it find out how much [...]

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 data between two device using a standard called RS232. RS232 is serial interface [...]

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 requirement is little more than that, like displaying some alphanumeric text, we [...]

Here I will highlight some features of C language commonly used in 8 bit embedded platforms like 8051, AVR and PICs. While programming microcontrollers in C most of the time we have to deal with registers. Most common tasks are setting and clearing bits in a register and check [...]

GPIO( General Purpose IO) is the most basic method of communication between MCU and external world. These are done with what is called a PORT. Ports are nothing but a set of bits physically connected to PINs of Microcontroller and available outside the chip. As we are working on [...]

Hello Friends, Welcome back. In the last tutorial we started working with MPLab and HI-TECH C Compiler and written our first C program to blink LED. After compiling the program we got the HEX file. Now, in this tutorial we will see how to transfer(burn) the hex file to [...]

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 software/hardware you will require and basic steps on how to get, install, configure and use them. After going through [...]
