This is a simple procedure to play PCM audio on any AVR microcontroller. AVR’s high speed PWM is used to play the audio. It almost sound fine and can be used for simple projects that require sound effects. The code is compiled in winavr GCC compiler. The microcontroller used is ATmega32, though any AVR processor

On this page you will find a scrolling LED sign based on the ATtiny2313 AVR microcontroller, which you can build yourself (when finished) Other names for this device can be: Moving message sign, Message crawler, Scrolling message, message display, etc. The idea is to let a text scroll over the LED dot-matrix displays. A dot-matrix
When I’m fiddling about with electronics I want to be comfortable about it. Therefore I built some things to make by breadboarding life a little simpler. One example is the Network Breadboard Interface. Another one is this little project. These little pcb’s can be put directly into a breadboard and they have the same pinout
This article describes the design of a Text on TV project. It takes serial data and displays text on a TV screen. The hardware part of this project is pretty simple. It uses an Atmega8 microcontroller that runs with a 16 MHz crystal. The article provides the details on PAL and NTSC timing signals, as
I usually drink a lot of tea, and sometimes the tea tastes a lot better than average, which means that most times I make tea I fail at least partially. The taste of the tea depends on a lot of variables: The make of the tea. I buy my tea at Simon Levelt and they
At the moment I do not have a kitchen timer. Not because I do not want one, (they’re cheap enough to buy) but because it seems impossible to buy a kitchen timer with a decent user interface. That means I have to build my own, which I just the kind of stuff I like. The
This project uses Atmega168 microcontroller to compute the power usage at home and logs it to an SD card. It has a graphical LCD display too that shows the power usage as a strip chart. Besides, the voltage and current waveforms can also be displayed on the LCD. The current is measured using a pair
