I was looking for an image of the Character LCD command sheet throughout the internet and failed to find any good resolution images that I can use for post references. Here is an HTML Version that could be used at whichever resolution you choose! Character LCD Command Sheet Instruction Code...

I was working on a project that involved the use of an SD (Secure Digital) card to log data into a text file. I chose Arduino as it had a vary stable FAT (File Allocation Table) library. I had an Arduino Mega at my disposal and built a resistive network...

What is the need for a clock line in digital communication protocols? This was a question that was posted on a Facebook page. I was surprised to see no one had posted a response. Probably they felt that the question was below standard, lame, stupid or on the worst case...

The Raspberry Pi 2 is a credit card sized single-board computer. This you must have heard at least a thousand times, against my better judgment I have planned to use the same opening statement for this post. Raspberry Pi comes as two variants and they choose to call it Model...

C is the most widely used programming language for Embedded Systems. Even today most of the low level tasks of operating systems are done in C. Linux is a native C environment and so, the two together make a good pair and cannot be easily missed. C is a high...

Ready made chassis that are available in the market (like the one above) are really good, cheap and for all you know they might have been subjected to an R&D before fabrication. In spite of all these advantages I still see the following issues with ready made chassis. They are...

Bored of the conventional line follower? People nearly are losing interest? Here is a post that could change it all and turn the winds to your side. Imagine if your robot was to start from node A (source) and move to node B (destination) and come back to node A!...

Programming a Line Follower Robot is the next step that you should do after building it. This is a follow-up on my previous post Line Follower Robot - Build it from scratch. If you haven’t already read it, I suggest you read it before going any further in this post....

Line Follower Robots are the most common type of robots that are built by hobbyist and students interested in robotics and embedded systems. The reason for the popularity of the Line Follower robot is the fact that it is simple to build and it is easy to understand the logic...
