Mini avr projects

2007-08: An AVR microcontroller based electronic dice, (PDF)
Simple but really cool: an electronic dice. Works even in outer space ;-)
2007-06: Mini 3 digit display, a small and inexpensive voltmeter module, (PDF)
We build a simple and inexpensive three digit display. It's a voltmeter module but it has also gerneral purpose digital IO pins.
2007-05: A simple digital thermometer, (PDF)
In this article we build not only a thermometer but see also how to interconnect a microcontroller to a linux PC over a physical RS232 interface without the extra MAX232 chip. The I2C protocol is used for the communication.

2007-09: Temperature and humidity measurements with the AVR web-server, (PDF)
Just add this one sensor and no other components to measure temperature + humitidy + dew point.
2007-04: An ethernet weather station, (PDF)
Add a sensor board to the avr-webserver/ethernet board and ready is the web enabled weather station with local LCD display.
2007-02: A LCD display with Ethernet interface, (PDF)
Here is another example on how our general purpose avr Ethernet board can be used. It's also interesting if you don't plan to attach a LCD to you hardware as it shows how to decode http-form data.
2006-12: Using the AVR microcontroller based web server, (PDF)
Examples of what can be done with our avr web server.
The article explains also how to connect it to the public internet.
2006-11: HTTP/TCP with an atmega88 AVR microcontroller (AVR web server), (PDF)
A complete web server in an atmega88!
It's the same hardware as the previous 2006-06 article. Just update the firmware to add a web interface.
2006-06: An AVR microcontroller based Ethernet device, (PDF)
A simple example application to switch on or off a relai via Ethernet from any computer in your network. The hardware is generic and ready for more complicated future applications. Welcome to the fascinating world of small microcontroller Ethernet devices based on the ENC28J60 Ethernet chip.

NEW: 2007-10: Tuxgraphics AVR NTP Clock, (PDF)
A nice clock that has always correct time and date thanks to the Network Time Protocol
2007-10: An AVR Oscilloscope Clock, (PDF)
Make your oscilloscope show the current time!

2007-05: AvrUsb500v2 -- an open source AVR Programmer, stk500 V2 compatible, with USB interface, (PDF)
A modern programmer for Atmel AVR microcontroller with USB interface. This one has no "chicken and egg" problem. That is: You can build it without building first a programmer to program the programmer.

2007-07: DDCP: digital DC power supply unit, (PDF)
A very small an really good DC bench power supply unit for your hobby lab. It has lots of features which you normally find only in very expensive power supplies. This one is affordable, small and easy to build.
