In this project, a digital voltmeter will be designed which will show the voltage reading on a desktop application. The device will read analog voltage with respect to the ground, digitize the reading and send the reading to personal computer on USB interface. The device could read four different voltages in range from 0V to […]

For my Word Clock project, for which I built a custom 8 x 8 LED Matrix with controller, I needed a much smaller footprint DIY-Duino (board for an ATMega328P microprocessor), one that would have all of the main functionality of my previous DIY-Duino boards (such as the Arduino Uno I2C Master board). As I’m not

A while ago I found some blog posts explaining how to use a LED matrix as a pendant (http://hackaday.com/2013/01/10/8×8-led-matrix-pendant-sealed-in-a-block-of-epoxy/ and https://sites.google.com/site/tinymatrix/ ). The 8×8 matrix pendant looked cool, but it was missing detailed information on which parts to use and how to solder everything together. With help from a friend, Uriel Guy, we managed to

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

There was a thread on the Raspberry Pi forums about running a 16×2 HD44780 based display off the ATmega chip on the Gertboard. I normally use a shift register to run my display, so I wasn’t much help to them. I decided to try and get it setup without the shift register to help out

Atmega fusebit doctor, as name says it, device for repairing dead Atmega and Attiny family AVRs by writing fabric fusebits. Most common mistakes or problems are a wrong clock source (CKSEL fusebits), disabled SPI programming (SPIEN fuse) or disabled reset pin (RSTDISBL fuse). This simple and cheap circuit will fix you uC in a fraction

In the Internet of Things movement, people across the globe are connecting their stuff – TVs, pets, even houseplants – to the internet and transmitting all sorts of data. If you’re going to be a part of that movement, or want to dabble in creative prototyping on a budget, it’s important to get to know

After I wrote several articles about using ATmega microcontrollers (DIP40) in Arduino environment I had some feedback that I was asked how to be effectively put into operation this project. As I came into the Arduino world from classical microcontrollers development world, I have not found necessary to elaborate a method or hardware project for

First, rise and shine, let me introduce you to my project. I’ve crafted an Alarm clock with extended functionality, including a thermometer and a humidity meter. Everything started when my friend (who used to bring me some old electronic rubbish and I used to check if there’s not something useful) brought me some cashing register

JabberBot is controlled via an Android application over a bluetooth serial connection. The guts of it are based on an I2C adaptation of the Adafruit WaveShield and MotorShield. The bluetooth module is a Bluetooth Mate Silver from Sparkfun. What does this thing do? The android app running on the phone (powered by CyanogenMod) connects to the
