Magnetic Levitation

Magnetic Levitation using the Arduino Using Atmega

It’s been only a couple weeks since I discovered Arduino, an open source microcontroller platform. I was looking for a cheap interface between my laptop and electronic circuits. Arduino with its price $35 and easy to use development environment was the best choice. So after getting my Arduino Duemilanove board and ordering some cheap components from AllElectronics, I had

Gmail and RSS Notifiers using the Arduino Using Atmega

I’ve been really interested in doing J4mie’s Physical Gmail Notifier ever since it came out in February. I only recently dropped into the project and got to learn a lot about python, plists, and arduino auto-reset functionality. I’m going to share what I’ve learned because I think there are lots of other people out there struggling to make it

TW Devices

Working with TWI (I2C) sensors / Devices Using Atmega

Introduction The I2C is a multimaster, multislave serial single-ended computer bus and was invented by Philips in 1982. The atmel microcontrollers use a compatible  to I2C serial bus that is named TWI (Two Wire Interface). The  TWI supports serial communication at 100 kHz and 400 kHz. The master and slave devices that are connected to TWI bus have a

web configurable Xively logger

A web configurable Xively logger, build on AVR ATmega328

Xively (formerly Cosm and before that Pachube) is a platform devoted to simplifying the interconnection of devices and data with applications on the Internet of Things. It is an on-line database service allowing developers to connect sensor-derived data (e.g. energy and environment data from objects, devices & buildings) to the Web and to build their own applications based on that
