Have you ever seen a business card with a computer chip embedded on it? This one does. It has an ATtiny85 microcontroller chip that stores all your personal details. You plug it into an USB port of your computer, and find the details about the person opened into a text editor. Read more: USB business […]

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) of

Detecting colour of an object can be an interesting and useful electronic application. It can be realized using a colour sensor like TCS3200 and a general purpose microcontroller like AVR ATmega32. TCS3200 Colour Light to Frequency Converter Chip TCS3200 chip is designed to detect the colour of light incident on it. It has an array

New version released ! V2.45 (Check version list for details) This construction is based on HappyJTAG Idea, to implement JTAG interface into target avr system and debug it remotly via USB, without specific JTAGICE hardware. All job is done by PC softraware. HappyJTAG version is easy , but not powerfull enough.There is barriere with performance, if

Essentially another tutorial involving controlling DC motors. In this post I’m going to first alter a robot arm I had built previously from a beginners kit so that it can be controlled from Arduino. Then I’m going to write a series of posts on different ways to control the robot arm using Processing and other things. You should be able to

Introduction The purpose of this project was to design and implement a debugger for the ATmega644 that communicated through its JTAG interface and was capable of controlling program execution by setting breakpoints and accessing registers and memory. We have three main objectives in this report: To enable a user to properly download our code onto

it is very difficult to bootload Atmega chips when you don’t have proper knowledge about device signature ! each chips are associated with its own Signature.at the beginning I found very difficult in uploading bootloader file to Atmega 328pu and Atmega 328p-pu , although their are many different methods are already available in Internet ,it

One of the relatively unexplored topics in this week’s lecture was USB, the ubiquitous protocol that allows computers to communicate with peripheral devices (containing microcontrollers). Creating a USB device allows any computer to talk to it without the specialized software and hardware we’ve been using so far. For these two weeks, I decided to understand

This is the second part of my USB tutorial for ATtiny2313 and V-USB library. In the first part we learned how to get 3.3V from USB to power our circuits. In this part, we will expand our setup with following parts: Larger breadboard and additional jumper wires ATtiny2313 12 MHz crystal oscillator Two 27 pF ceramic capacitors
