This project gives you a real time clock with the RTC chip DS1307. This RTC chip has inbuilt oscillator for clock and it has its own registers for full calender. In this project we dont take... Read more
This project gives you a digital voltmeter which can measure voltage from 0v to 25V DC. The values are displayed over the 7segment display. Atmega8 is used and the internal ADC is used to me... Read more
The 4×4 LED Display was my first project with a two-layer circuitboard layout. The alignment was not 100% optimal, but sufficent. I wanted to make the board as small as possible, so the part... Read more
Aim of this project is to present a way to store a large quantity of data into microSD card in files with FAT32 format. Here, ATmega32 is used for data collection and microSD interface. The... Read more
For a long time I had a layout for this circuit, but could never build it, because the layout was to small to be made by tonertransfer. So it was the first layout I made with my new exposure... Read more
I am presenting one application with the Nokia 3310 LCD: Designing a thermometer using DS1621 temperature sensor IC. DS1621 is 8-pin sensor from Maxim, with temp range of -55 to +125 degree... Read more
EPROM Display using ULN2308A microcontroller
Due to university and work it has been a while since the last post. But I just completed a little project that’s worth posting. Several old 27C256 EPROMS were lying around unused. So I thoug... Read more
Another update on the CNC. The interfaceboards are etched, soldered and tested. IO / Control Boards Step- and directionsignals are generated by an ATmega32 which is controlled over RS232. Th... Read more
And now for something completely different: A little robotics project for the weekend. The described robot can be build entirely from model making supplies and materials from the hardware st... Read more
Introduction: (don’t skip to read the note below) I recently purchased few AVR microcontrollers. I don’t know much about AVR since I am using it for first time. Any way, I have s... Read more
