A line follower robot, or a LFR in short, is a simple autonomous robot that optically tracks a line made on the surface of the floor. That means you have an arbitrary line drawn on the floor and the robot ...

You can use this LCD Custom Char Builder Software to quickly and easily build custom characters for alphanumeric LCD modules. ...

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 ...

We wish all our friends a very happy Bengali New Year !

Hi All, We are planning to make our Software eXtreme Burner - AVR available in your local languages! So we need translators. Those who are interested in translating the app may leave a comment here, so that we can contact you ...

Hi All, I was adding support for some chips with big flash memory (like ATmega2560 etc.) in my Programmer Software eXtreme Burner - AVR. But right now I do not have any ready setup with ATmega2560 so I ask anyone of ...

One of the most common place where small MCUs are used is to drive big seven segment displays in public area. For example the bank token number, flight or train schedule, train coach number, production volume (in factories), current forex(in ...

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 ...
