Temperature monitoring have wide application in daily life. In modern day keeping an eye on temperature of places such as server rooms, hospital rooms, warehouses and green houses can help solve many problems. But with the use of normal ...

Just what is a microcontroller? To get you understand quickly I define a microcontroller as a single chip computer. Yes it is a full blown computer in its own. It ...

If you have worked with AVR's USART you must be knowing that the first step is to figure out the value of UBRR (USART Baud Rate Register) the formula is given in the datasheet. So every time you need a ...

Detecting colour of an object can be an interesting and useful electronic application. It can be realized using a colour sensor like TCS3200 and a general purpose microcontroller like AVR ATmega32. TCS3200 Colour Light to Frequency Converter Chip ...

Hi friends ! Here I am showing a microcontroller based project called the "GSM Based Voting System". Using this system you can ask your users to vote for any of the four options. Four available options are identified by a ...

Hi friends in this part we will have a look at the functions related to text messages. By the end of this article you will have a clear idea of how to wait for a text message, read the message, ...

One of the most basic autonomous robot you can build is a line following robot(LFR). This type of robot is run over a white surface which has an arbitrary path drawn over it by using back paint. The task ...

An interesting project that can be done using Microcontroller is a LED message scroll er. It teaches you a quite lot of things. So I decided to make one. I made the hardware design modular and cascadeble That means the ...

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 this tutorial we will discuss a simple PC controlled robot. The Robot PC link will be a RS232 serial line. The robot will have only five commands. Move forward (RS232 char 'F' or 'f') Move backward (RS232 ...

This mini article provides a small circuit idea to interface a 12V or 24V DC Solenoid (or relay) with a 3.3 or 5V microcontroller's i/o pins. Datasheets BD139 Power Transistor (For PINOUT refer this document)

GUI Frameworks of all modern OS like Windows, Linux (Qt & GTK+), MAC etc have a concept of standard dialogs. For example all applications running under Windows shows the same file open dialog for selecting a file. Similarly their are ...
