What is a tilt sensor? Tilt sensors allow you to detect orientation or inclination. They are small, inexpensive, low-power and easy-to-use. If used properly, they will not wear out. Their simplicity makes them popular for toys, gadgets and appliances. Sometimes they are referred to as “mercury switches”, “tilt switches” or “rolling ball sensors” for obvious […]

If you ever wanted to integrate RFID functionality into your project, this small tutorial might help you accomplish that. I used the RDM630 module from seeedstudio in its UART version. It comes on a small board with presoldered connectors which fits perfectly on a breadboard. You only need to connect the antenna to the two pin socket. […]

Seeing so many persistence of vision ideas on the web was too tempting not to try one. After considering several different motors to drive a display, a ceiling fan seemed to run at just the right speed, is out of the way, and very quiet compared with alternatives. With a micro controller based on the […]

n present time home office appliance controlling is common thing.  Today for controlling home/offices appliances, machineries in companies/industries uses different types of automation systems like DTMF controlled, GSM controlled and many others. So here this project is made for interfacing MATLAB (Graphic User Interfacing) and Home/office/industries automation using Arduino and MATLAB. Here MATLAB is interfaced with […]

Ever wanted to be “logged in” to your AVR microcontroller? Ever thought it would be cool to “cat” a register to see its contents? Have you always wanted a way to power up and power down individual peripheral sub-systems of your AVR or Arduino in *real time* ? Me, too, so I wrote the AVR […]

By: Charlie DeTar, Christina Xu, Boris Kizelshteyn, Hannah Perner-Wilson A digital wind chime with hanging acorns. Sound is produced by a remote speaker, and data about chime strikes is uploaded to Pachube. Step 1: Brainstorming for a device that would represent ourselves Our goal was to come up with a project which represented our personalities, […]

Our first open source Homeland Security non-lethal weapon project – The “THE BEDAZZLER: A Do-it-yourself Handheld LED-Incapacitator”. After attending a conference where the $1 million “sea-sick flashlight” (named “THE DAZZLER”) was demonstrated by the US Dept. of Homeland Security, we decided to create our own version. For under $250, you can build your own dazzler […]

In this tutorial you will learn how to read the status of a digital pin of Arduino. I hope that you already go through our first tutorial, Getting Started with Arduino Uno – LED Blinking. In this example, a push button switch and an LED is connected to Arduino Uno. When we press the switch, LED will glow for […]

Introduction In this project, 16 LEDs are used to represent the time in binary. The time is read from a Real Time Clock breakout board – the same one used in the Digital Clock page. The binary clock uses 4 place values for the hour (12hr format), 6 place values for the minutes, and 6 […]
