Since this blog acts as a kind of documentation for the kinds of projects I've involved myself with, I thought, hey why don't I put up something that I worked on on the year of 2014. Something of a little throwback just in case someone stumbles across this blog. So, back then, this project was the first, in search of a better word, "big" project that I had done. In this particular project, I used a Atmega16 micro controller. To be more specific, I used a development board which I got from here . Now, with this I wanted a robot that could be controlled from a distance, like an RC car. But, in this case, I wanted the range of it  be the entire world. So, how did I do that? To understand that, let's start by asking what DTMF is. So, DTMF stands for Dual Tone Multi Frequency. Essentially, when you dial a number on your phone's keypad, each number produces a distinct touch tone. This touch tone, is essentially a combination of two sound waves; one of a higher a...

Recently, I've been pretty busy with university classes and exams. To get my mind off the exams, I've made a simple program using OpenCV. If you've ever had an interest in digital images are made or photography in general, you might have heard about "pixels". In essence, every image that you see on a computer screen consists of small points of colors called "pixels". All of these small points of color, when viewed as a whole, make up an image. Well, without going too much into the details, these pixels are made up of three colors; red,green and blue. Generally, each color is made up using 8 bits of memory. So, effectively, you can set each color as a value between 0 and 255. Just think of every image as a combination of red, green and blue where the value from 0 to 255 represents how much of each color there is.Knowing this, I got to thinking that it would be pretty fun to to see EXACTLY how much of red, blue and green there is in a sample image. And...
