Description This is a Dot Matrix Scrolling Sign. A Dot Matrix Display has an 5×7 led matrix with 5 columns and 7 rows. The display is controlled by the AVR microcontroller. The rows are controlled by PORTB of the microcontroller, while PORTD puts the data on the columns to make the characters. The Dot matrix […]

How to program a 93C66 EEPROM chip with an AVR microcontroller? The 93C66 is a serially (MICROWIRE) Electrically Erasable Programmable ROM (EEPROM) chip with 4 kbit (4096 bit, can be ORGanized as 256 x 16bit or 512 x 8bit) memory space. Here a DIL version (which I will use in my moving message sign project)

Another version: In this version I took PORTB of the AT90S1200 AVR microcontroller as you can see in the diagram, because this makes it simpler to let 8 LEDs flash back and forth. Set the Data Direction Register of port B as an output, the output will source current. What I did is loading an

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

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 morning (2009-12-31) I built my 4th AVR programmer. USBasp. I built this one because I wasn’t completely happy with my 3rd programmer and because I want to play with a software USB stack. I do know that it works (I just reprogrammed 2 old projects just to try it out. Programming seems to be

The programmer I use is built from a kit I bought at Tuxgraphics. There are several reasons I bought this kit. It is open source, works with avrdude. It connects to USB. It is a lot faster then my old programmer (Programs an ATMEGA8 in about 5 seconds). It is cheap. I bought the kit

Designing a professional digital oscilloscope is a pretty complex task wich makes them also pretty expensive. Therefore I concluded it’s nothing more than a daydream to design one of those. It’s far more realistic to limit the design of this instrument to something a bit more realistic. If you connect something like the JYE Tech
