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
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

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

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
The Arduino is the ultimate tool in the Maker’s arsenal. You should be able to build your own! In the early days of the project, circa 2005, the design was all through-hole parts and communication was via a RS232 serial cable. The files are still available, so you can make your own, and I have, but not many computers

Serial communication was once the most widely used method of transferring data between computers. Many computing devices that you have used over time employ serial communication. Some of the terms associated with this type of data transfer are FTDI chip, COM interface, the RS232 protocol, and serial port. Serial communication refers to data that is

Greetings, One late night of web surfing I came across some 45 Degree Extension boards. Thinking to myself “Wow!” that’s cool and then I looked at the price…$27.00 before S&H. “Yikes!” I’ve been looking for an excuse to learn Eagle PCB layout software and this was the project I decided to cut my teeth on…”Wing
