Over the past few days, I received a plethora of emails and messages on how to make a line follower robot. Mostly, the specification being white line on a black surface. Some even mentioned shortest path detection loops in the track. Now, I do get emails in which people ask...

At some point in time we all have had to develop some sort of UI for our embedded devices. The thing about UI design is, it can take one hell of a time before we can get it right (and it’s a thankless job! I have my reasons). I for...

External event counters are pretty useful things to have around. Once I had a feud with a shopkeeper for selling 4 motors in 3 different RPMs. Well, I don’t know if you have ever tried making a robot that had wheels rotating at different speeds, I did. It wasn’t a...

There is CCS (Code Composer Studio) IDE for programming and debugging the Launchpad. It includes an optimizing C/C++ compiler, source code editor, project build environment, debugger, profiler, and many other features. Also, the presence of Control Suite, a support software containing libraries and examples makes the learning easy. Note: I...

You might think its pass time while I was talking about simple electromagnetic bells at my blog. Truth be told I would agree with you and embedjournal is pitching for a higher game in the near future. We will soon get into some android programming and write mobile apps that...

Input voltage measurement of an embedded device is not as simple as it sounds. But if estimated, can come in very handy in a number of occasions. In this article we will see how we can add this feature to your embedded system with minimal components. It is one thing...

Books are an invaluable source of information. Listed below are some books that we feel, will help you understand the basic concepts behind embedded systems, robotics, and basic electronics. Check if you have come across some of these books and leave a comment if I have missed some good books....

Your Desktop-PC doesn’t have a Serial Port in the back side? Don’t be so sure of it. If you can’t see it, doesn’t mean it ain’t there! All you have to do is look properly. If you are a full-time laptop user, stop right here! This article is of no...
