In this article I will try to tell you about the gift I made for my girlfriend! I got here is a LED heart. I apologize for my bad English! The basis of the scheme is a microcontroller Atmega8, 1K resistor, selected in such a way as not to overload the microcontroller ports. SMD resistors […]
Even your device can be more user friendly thanks to various pictograms displayed on Winstar WEG series displays with a great contrast and viewing angle. 100×16 pixels at series Winstar WEG010016 isn´t that much at the first sight. But when we realize, that such display represents a sort of a “replacement” or “upgrade” of a character display

For many of my previous projects I used AVR Microcontrollers extensively. I started with the Atmega8 and moved to superior AVR variants depending on the application complexity and requirements. Before designing any particular application, I usually do my research on a development board. It is a PCB featuring the target microcontroller and minimal support logic that usually covers a

The MicroGame is an experiment of making a custom portable platform for gamming compatible with Arduino. It’s based on a small monochrome 128×64 pixels OLED from Adafruit and a ATmega32U40 8-bits microcontroller running at 8MHz. All hardware design and game source code is writed from scratch and you can find all the file sin this

For those of you who remember the eighties, this will no doubt bring back fond memories when every piece of audio equipment in the known universe was at the time equipped with a plethora of LEDs. More specifically the ubiquitous Graphic Equaliser or ‘Graphic EQ’. This Instructable is centred around the MSGEQ7 to create a

Motivation Though I am a musician I don’t care for calling an expensive hi watt stereo my own. For years I have used a homebuilt stereo amplifier built around the TDA1554Q IC (basically just this chip in a nice box) and I am still very happy with the sound quality. This amp serves as a

Drilling holes in homemade PCBs is greatly simplified with an computer-driven coordinate table on a drill press. The clue is the on-the-fly calibration technique, so it does not matter where exactly the PCB lies on the table. You only need to move to two drill holes by hand, then the computer knows how to drive

Summary A mousetrap is a type of animal trap specialize to catch small animals, particularly rodents like rats, mice, hamsters, etc. This project is a kind of mousetrap that is intended to keep a captured animal alive. In this way, the hunter can release the captured animal later to the wild. The PIC12F683 microcontroller acts

The term mechatronics engineering was coined in Japan during the 1970s, used to describe working in robotics. It has since developed as a practise encompassing electrical, mechanical, electronic and control engineering. Mechatronics combines these areas of the industry to allow the development, design and application of smart devices in an integrated, cross-disciplinary manner. Today there
