Mint-Sized Success Meter (quit smoking!) with Arduino

There comes a time in life to put childish things behind and give up nasty habits. Some, like smoking, can be damn hard without constant encouragement. It was time for me to combine my favorite hobby with my driving goal and make this: The Quit Success Meter! For my other Arduino contraptions, take a look at thoughtfix.com Step 1: Parts, Tools, and Component Preparation The links all go to the components I ...

Arduino Fingerprint Lock

There is a short video for this Arduino fingerprint lock here: http://v.youku.com/v_show/id_XNjIxNzQyNzY4.html I live in a small apartment in Shenzhen with my wife and baby, 5 months old.  Sometimes, I need to go out, for example, to go downstairs to buy candy or diapers for my baby. But always I forget to carry my keys, so I need to knock at the door or call my wife to open the door for me, and, always wak ...

Arduino AVR Progamming Shield

Do you need a quick and easy way to program AVR chips. Did you know you can use your Arduino and the Arduino IDE? This Arduino shield makes the process much easier. You can: Burn a bootloader onto a replacement Atmega328 for your UNO. Make a stand-alone Atmega328 breadboard project. Use inexpensive Attiny chips for smaller projects. Reprogram a chip in an existing circuit with an ISP header. This shield let ...

Arduino Snail Mail Notifier

My mailbox is across the street from my house because our mailmen don't walk door-to-door, so I never know when the mail is delivered. Sometimes, I'm waiting for something and I'd really like to know when it arrives. I got my first Arduino last week, and thought it might be a neat toy project to build a notifier that would tell me when the mail is delivered. It's designed to live inside the mailbox (I have ...

Slipper Shining with LED strip & Xadow

mo.momi Led strips are amazing! Firewalker-led-sneakers(http://learn.adafruit.com/firewalker-led-sneakers) by Adafruit inspired me. I wanna change a way to control it, instead of "pressure-sensitive", I use a accelerometer sensor judging the motion of slipper. It's simple, I complete this version only calculating the acceleration on "z" axis, weather i'm speed up or slow down. Led will "flow" if I'm moving, ...

The Rise of Chip-on-Board LED Modules

By Steven Keeping Contributed By Hearst Electronic Products 03/11/2014 Until recently, a lighting designer looking to take advantage of the efficacy, longevity, and robustness of LEDs for his/her next luminaire was faced with some key challenges. Among the toughest of these was the need to work out how many discrete LEDs were required to achieve the required “lumen density” (light output per unit area) for ...

Arduino Esplora Blink Code

This sketch blinks the Esplora's RGB LED. It goes through all three primary colors (red, green, blue), then it combines them for secondary colors(yellow, cyan, magenta), then it turns on all the colors to create white. For best results, cover the LED with a piece of white paper to see the colors blend. Circuit Only your Arduino Esplora is needed for this example. Connect the Esplora to your computer with a ...

Analog Input using Arduino

A potentiometer is a simple knob that provides a variable resistance, which you can read into the Arduino board as an analog value. In this example, you'll connect a poterntiometer to one of the Arduino's analog inputs to control the rate at which the built-in LED on pin 13 blinks. Circuit image developed using Fritzing. For more circuit examples, see the Fritzing project page Connect three wires to the Ard ...

Yoga Breathalyzer

The yoga breathalyzer is a breath visualization tool to help you understand and get in touch with your breathing. Breath is the basis of yoga and meditation, and this biofeedback tool is one way to develop a deeper understanding of your own breath. Using Arduino, a headset-mounted wind sensor, and an LED strip, it's simple to translate your breathing into visual output. This project was created at the Silic ...

Re:Load Pro – A DC active load

A constant current load for testing your projects. 6 amps, 60 volts and 25 watts in a workbench-friendly package with a USB interface. What is the Re:load Pro, and why do I need one? The Re:Load Pro is an active load. It acts as a current sink, always drawing the same amount of current regardless of the voltage across it. Active loads are incredibly useful for all sorts of electronics testing requirements. ...

Sonic Switch: Use a Sonic Screwdriver to turn on your computer!

What it is: An Arduino-based light-sensitive switch for turning on a desktop computer. Why its cool: Use a Sonic Screwdriver to turn on your computer! Story: This project started, as I'm sure a lot of them do, as a result of boredom and the thought "Wouldn't it be cool if...". I am a fan of Dr. Who. Enough of a fan, I suppose, to spend money on a plastic replica of the good Doctor's Sonic Screwdriver (http: ...
