Introduction Ever dream of having a darts game scored automatically without using those annoying plastic darts? We decided it was a dream most of us has had at some point, and so decided to implement an automatic scoring system for a “real” cork dartboard. As college students, we found darts to be a great way […]

Combo Blocks using an Arduino
Project by CU Boulder Thinks That Think students: Michelle Bourgeois, Charles Dietrich, and Ben Link Imagine having a safe in which the combo is any small object of your choosing. Perhaps it’s your favorite coffee mug, or a bat man figurine. This project is based on this idea, using the weight and placement of your […]
Arduino-based line follower robot using Pololu QTR-8RC line sensor
UPDATE FEB 2012: This guide is featured on Adafruit’s blog http://www.adafruit.com/blog/2012/02/14/arduino-based-line-follower-robot/ This is Faz3a II, my first line-following robot, which I also hope to use for maze-solving. I used the Arduino Uno, Adafruit motor shield, Pololu’s QTR-8RC line sensors and motors. You can build a cheaper and lighter version of this robot using the Atmel […]
Arduino-Square with Color LCD
B-Squares is a modular electronics platform that enables users to build, customize, and continuously update their own electronics applications. In this B-Squares App we will cover how to assemble a simple Color-LCD Application using the Arduino-Square. Hardware: 1. Arduino-Square. 2. Battery-Square 3. Color LCD Shield. 4. FTDI USB connector (3.3V). Software: 1. Arduino Software. 2. BSQ-ColorLCD […]
Clock Two – Single digit clock using Arduino
Time for another instalment in my irregular series of clock projects. (Or should that be “Time for another instalment in the series of irregular clock projects”?) In contrast with the extreme “blinkiness” of Clock One, in this article we describe how to build this single-digit digital clock: Once again the electronics of the clock will […]
Arduino Automatic Watering System For Plants Sprinkler
Last month, Elecrow have left from the original office and moved to a new office. We will miss our original office where we worked so hard for more than two years, we will miss everything here, the desks, the windows, and those potted plants, that we cared for more than two years with our neighbor. […]
Arduino Charliplexed Heart, Just in Time for Valentines Day.
Here is an Arduino controlled Charliplexed LED heart just in time for Valentine’s Day. It uses a total of 6 wires to controll the 27 LEDs. A PIC or AVR could easily be used for this, but I have Arduinos lying around and they are easy to program. Plus I want to be able to […]
uDuino: Very Low Cost Arduino Compatible Development Board
Arduino boards are great for prototyping. However they get rather expensive when you have multiple concurrent projects or need lots of controller boards for a larger project. There are some great, cheaper alternatives (Boarduino, Freeduino) but the costs still add up when you need many of them. This is a way, after about $25-$30 initial […]
USB Game Pad With Tilt-accelerometer Mouse using an Arduino
Make a game pad with an accelerometer inside! This project tutorial will show you how you can convert a console game pad into a USB keyboard mouse for playing games on your PC. The USB game pad can be used with nearly any software, such as a MAME emulator, game, simulation software, or for custom […]
Secret Knock Detecting Door Lock using Arduino
Protect your secret hideout from intruders with a lock that will only open when it hears the secret knock. This started out as a bit of a joke project, but turned out to be surprisingly accurate at judging knocks. If the precision is turned all the way up it can even detect people apart, even […]
