In this project, you’ll learn to read an RFID tag using the Innovations ID-12 reader and an Arduino Duemilanove. Step 1: Let’s Get Started! We’ll be using the ID Innovations ID-12 to perform the task of reading an RFID tag. At a minimum, it requires +5V, ground, and a digital pin (on the Arduino) that […]

This is one of the first projects I have made with Arduino. It’s a little siren with a LED that fades and blinks on and off. It demonstrates basic use of LEDs and speakers. Also check out this article: 8-Pin Programming Shield Constructive criticism is appreciated! Let’s get started! Step 2: Solder jumper wires

The Memsic 2125 (datasheet) is a two-axis accelerometer capable of measuring acceleration up to plus or minus 2g. It has a simple digital interface: two pins (one for each axis) emit pulses whose duration corresponds to the acceleration of that axis. By measuring the length of that pulse, in microseconds, using the Arduino’s pulseIn() function,

Have you ever wondered how migratory birds manage to have such an amazing sense of direction despite being so generally clueless? They can sense the Earth’s magnetic field with what is basically a compass built into their body. Wouldn’t it be cool to feel what that’s like? The following instructions are loosely based off of

Welcome to my ‘green’ instructable! I am going to show you how to use an Arduino, two servo motors a temperature sensor and some metal (or wood) to make a digital thermostat for a through-wall HVAC unit. According to CB Richard Ellis (a major real estate firm), New York City is a renters market, with

A while back I saw an EMF (Electromagnetic Field) Detector at makezine.com that used a led bargraph. I decided to modify it to use a 7-Segment LED Display! Here’s my project. Sorry I don’t have any pictures of it in use. Hopefully I can post some soon. Credit goes to Aaron ALAI for the original

This example shows you how to monitor the state of a switch by establishing serial communication between your Arduino and your computer over USB. Hardware Required Arduino Board A momentary switch, button, or toggle switch 10k ohm resistor breadboard hook-up wire Circuit image developed using Fritzing. For more circuit examples, see the Fritzing project page Connect three wires to

In this project, we will use the chipKIT Uno32 board to build a digital stopwatch capable of timing minutes, seconds, and 1/10th of seconds, and with a basic start and stop control feature. A MAX7219-driven 8-digit seven segment LED display is used to display the time elapsed. The Reset switch on the Uno32 board will be used

For a class, my teammate and I decided to develop a MIDI based system that has a responsive light for each note played. For example, if you plug our little setup to a keyboard, pending on which note you press, you’ll get a specific color. You’ll need a list of several items, but the reward

I am currently living in a college dorm. Like most dorms it’s about the size of a tissue box but less comforting. Fortunately, my room has a heater/AC with four positions: low, medium, high, and off. Unfortunately in winter an hour on the low setting makes the room a stifling 80 degrees and when turned
