This is a fun speaker timer I made for some upcoming conferences. It uses a 4-digit charlieplexed LED (pseudo 7-segment) display and is driven by a AVR ATMega328 or an Arduino. It allows a default time to be set, can be paused, and will put out 5 Volts on several IO lines when 10, 5, 1, and […]

Soldering SMD components isn’t as hard as you might think. In fact it’s easy. If you follow this instructables you’ll soon see just what great results you can obtain at home using just a hotplate. It’s not just being able to make small circuit boards that makes SMT soldering so good it’s also a nicer

Description A long time ago I bought a couple RGB rotary encoders from Sparkfun because they were cheap and I was already spending a bunch on other stuff. I thought they would be neat for some interfaces since it includes a push button. The interrupt service routine (ISR) for pin changes on the rotary encoder (for terminals

This Instructable will show you how to build your own Web Connected Robot (using an Arduino micro-controller and Asus eee pc). Why would you want a Web Connected Robot? To play with of course. Drive your robot from across the room or across the country, using nothing more than Skype and a web browser (nothing

Introduction This project is implemented with a glove, resembling a conducting baton that analyzes gestures and interprets them into musical elements. Der Kapellmeister is a simple tool that tests a user’s ability in basic conducting, using a real conducting baton. As a user performs a gesture, the tool will display the tempo, time signature, and beat

This is a mutli-mode clock project based on attiny2313. it employs a 8×8 led matrix as display. with the limited resolution, this 12 hour clock shows time in 6 different modes. The circuit employs row and column multiplexing to drive the leds, one row at a time, this gives a 12.5% duty cycle when “sets” of leds (8 of them

[Updated Sep 30] — Arduino announced the first open source Arduino hacker board with built-in WiFi, and also the first to run Linux. The $69 Arduino Yun integrates the functions of an Arduino Leonardo, featuring an Atmel ATmega32U4 microcontroller and 14 GPIO pins, with an Atheros AR9331 WiFi SOC running OpenWRT embedded Linux on a

First, let me introduce you my project. I made an Alarm clock with extended functionality & thermometer and humiditymeter. 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 display similar like that. When I first
