Introduction: This is just a time pass hobby project, I am trying to display some pictures (JPEG/PNG/BMP etc) on my 8×8 led dotmatrix display. You can see photos of my 8×8 led dotmatrix display showing some grayscale pictures. The main thing which you may notice is that the brightness of each led depends on the […]
Introduction: I have learned some thing about TV in one of my B.tech semester but I forgot most of them. Now I refreshed a few basics and tried to implement a monochrome PAL TV signal generator using an AVR micrcontroller. I was using PIC earlier but later I jumped to AVR because I loves the

Introduction: I am interested to draw lines, square, rectangle, circle etc on my TV screen. At first I was confused where to start. While thinking about it, a pencil and an eraser came to my mind. If we have a good pencil, eraser and a paper, then we can draw on it according to our

Now it is the first time I am using an arduino board. Arduino mega 2560 is really a great product. The chip got a flash of 256KB, RAM of 8KB and EEPROM of 4KB. Also, the data sheet of Atmega2560 says that we can extend the RAM (by external) upto 64KB. Another most important feature

“All waveforms, no matter what you scribble or observe in the universe, are actually just the sum of simple sinusoids of different frequencies.” Hi, I am just refreshing the basics of fourier transform. I am not an expert. Now I did a small audio spectrum analyzer(0 – 10KHz) on a 16×2 character lcd using an
