This page explains how to build an RFID reader with just an Arduino (Nano 3.0 was used in testing, but other models may be compatible), a wire coil made by hand, and various affordable common components. Credits The hardware and software designs for this project are based in part on the ideas, code and schematics […]

1. Introduction As the portable electronics industry has advanced over the years, various requirements have emerged, including longer battery life, smaller and more affordable systems, brighter full-color displays, and increased talk time for cellular phones. The growing demand for power systems has made power consumption a critical concern. To meet these demands, engineers have focused

This project is designed to help you construct some relay boxes for controlling power from your wall socket using an arduino or microcontroller. The inspiration for writing an instructable came when I decided to build some relay boxes for my personal Garduino project. For safety concerns I started designing my own relay circuit and outlet until I came

Hi. I’ve just got myself an Arduino Uno R3 and I’m really new in the world of Arduinos. There’s so much to learn and explore 🙂 One of the first shields that I’m tempted to buy is the Prototype Shield. I think building a prototype circuit right on top of the Arduino is pretty slick.

I love my Arduino. It got me into, and hooked on, microcontroller programming. I also like the expandability that shields provide. My Arduino can be a GPS Locator one minute, and be connected to the web the next. There’s also a kit that lets you make your own shields. That last option always bothered me.

This project emulates a trumpet by playing notes using the three buttons (valves). This is easy to make and fun to play with, though it can only play one octave and no sharps/flats. Step 1: Code Load this into your Arduino: int speaker = 9; // Hook up speaker to digital pin 9 int sw1

The Twittering office chair “tweets” (posts a Twitter update) upon the detection of natural gas such as that produced by human flatulence. This is part of my commitment to accurately document and share my life as it happens. For more in depth theory, please see the next step entitled Theory. See the results of the

An all-in-one tutorial to getting started with the Arduino open-source electronics prototyping platform. This guide is meant for the beginner but should be also be useful to you if you already tinker with electronics but want to get started with the Arduino. I’ll cover: – breadboarding LED outputs from the Arduino – creating and reading

First and foremost, I must acknowledge that I am standing on the shoulders of giants, and that every giant is standing on the shoulders of giants (such as all contributors to instructables). If it weren’t for the unknowably many people who had the mindfulness to freely share information, this would have been utterly impossible; I

So I mentioned in an earlier Instructable that I am a teaching assistant (TA) for an introductory engineering course for biomedical engineering majors at Vanderbilt University. My main task as a TA is to re-write a few laboratory exercises that the students will be performed during the class. One of the laboratory exercises was to
