Intro: If you’ve got an Arduino Uno and want to start duplicating projects without having to buy an Uno every time… get ready to live! This instructable will show you how to move your projects (that do not require serial communication) onto a breadboard for prototyping or expansion. If you’re looking for a more permanent

When you are tinkering around with your Arduino and a breadboard you might want to make yourself an “Arduino Bracket”. Nothing more than header pins and a piece of wire, the “Arduino Bracket” keeps wiring neat and tidy, and lets you easily disconnect your Arduino for use in other projects. Step 1: Gather Necessary Supplies

As summer is coming, I bought a USB fan from HuaQiangBei, Shenzhen. However, when I focus myself on work(or game), I could hardly notice its existence. If I can teach it how to think and execute its duty without my order, that will be more practical and fun! So roll your sleeves and follow me

Sometimes you may do something stupid, other times it is totally inexplicable but as a result of whatever events, the green power light on your Arduino stopped coming on. In my case it turned out to be a burned out voltage regulator. This inscrutable is a explanation on how to replace it and identify the

This example demonstrates the use of INPUT_PULLUP with pinMode(). It monitors the state of a switch by establishingserial communication between your Arduino and your computer over USB. Additionally, when the input is HIGH, the onboard LED attached to pin 13 will turn on; when LOW, the LED will turn off. Circuit image developed using Fritzing. For more

This instructable will show you how to build an Arduino shield that adds another Atmega168/328 on top of your Arduino, giving you an extra complete set of I/O pins to use. That’s 12 PWM pins, 12 Analog pins, 4 external interrupts, or 40 Digital pins total. ———————————– *UPDATE* 3-11-10 I re-did the Eagle file and scrapped

Good news, everyone! I just started with the arduino and right at the very beginning I felt that I needed some sort of base to put the arduino on. I was reading one article from ladyada (http://www.ladyada.net/images/arduino/bumperplace.jpg) and she was using some rubber bumpers on the bottom of the board. I thought about that and

I enjoy both Geocaching and electronics and have made a couple of electronic puzzle caches using an Arduino. My latest creation (with the help of a fellow cacher for the code) is using an Arduino and RFID reader to make a puzzle geocache we call RFIDuino. The GeoCacher takes RFIDuino and has to find 3

ButtonHero is a game made on an Arduino that involves the use of buttons, LEDs, wires, and resistors. In this game, you have to hit the corresponding button to the light that is randomly selected before the light changes. You start with 5 lives and missing or being too slow subtracts one life. The high

There is no better way to hide a covert device than to stick it inside a larger conspicuous device. That said… Essentially, this is a guide for making a data logging system for use with the breathalyzer microphone. To accomplish this, an Arduino and a Logomatic SD data logger are embedded into an old and
