Make a 8×10 L.E.D Matrix using the Arduino and 4017 decade counter

In this instructable I will show you how to build a quite fancy 8 by 10 L.E.D matrix(with scrolling text and animations) using the Arduino and 4017 decade counter. This type of matrix is easy to make and program and it is a good way learn how to multiplex. I have added another part to this instructable about using the 74HC595 shift register which will help to save some arduino pins for other thing you would ...

LED Binary Calculator using Microcontroller ATtiny2313

You can't calculate binary values "as is" on most handheld calculators and using the windows one is just a pain, so i decided to make my very own (binary only) calculator. This calculator supports all the basic functions like : NOT,OR,AND,XOR, addition,subtraction,multiplication,division and modulo. So join me as we are going to enter the world of ones and zeros and play with some LEDs and switches along th ...

Debugging AVR code in Linux with simavr using Microcontroller ATTiny85

I recently started programming AVR chips, namely the ATTiny85.  They can be programmed using C, compilers are readily available in Ubuntu, and you can do a LOT with them - just search for avr on this site!  Anyway, I was having some trouble with my project today - the LED wouldn't flash!  I couldn't figure out what was going on, as debugging these things is non-trivial.  That is, until I discovered simavr. ...

Power your Arduino/AVR with a Hand-Cranked Battery

If you've ever wanted to power your Arduino or AVR from a battery for development testing (batteries have different power delivery qualities than, say, transformed AC or even a regulated wall wart in DC) testing but were tired of going through batteries (Hey, I admit I've sucked batteries dry in hours because of a slipped-up design before I caught it). Maybe you want to take your design and project mobile, ...

USB controlled home automation hack using Microcontroller ATmega8

Hack a wireless home automation system to be USB controlled using two AVR microcontrollers! Check out the video! The system is really more responsive, but the browser on my phone is slow. Skills ans tools There are two ways of hacking an RF remote to be controlled by a computer or a microcontroller. The lame way: Soldering wires onto the button pads on the remote and hooking them up to an Arduino. The cool ...

Music Playing Alarm Clock using Microcontroller AT90USB1286

This Instructable will be about designing a music player from using various building blocks. You will understand the communication between the microcontroller, memory, computer, LCD display, RTC, IR remote, and the music file decoder. I will try my best to to teach you in a way so that you can design your own projects using the skills you learn, without blindly following instructions. I know most of you wil ...

Rechargeable Battery Capacity Tester using Microcontroller ATMega168

Do you have a pile of AA rechargeable batteries in your drawer? Some are old, some are new, but which sets would you bring with your camera on your next trip, and which ones are past their useful life? I like using rechargeable batteries, but I’m certain that some of them are not living up to the stated capacity on the label. So how good are those batteries? Simple battery testers measure the voltage, but t ...
