This Instructable explains how to use a gas sensor with your Arduino. This lets your Arduino smell (and hence you program responses to) overall gas levels for a variety of nasties, including ethanol, methane, formaldehyde, and a bunch of other volatile organic compounds. My cost to make this actual device was under $100, including the […]

MIT has developed a fantastic visual programming language called Scratch. It is also an amazing learning tool for children, because it is simple, cute, and by providing interaction with the real world by a board called “Scratch Sensor Board”. This Instructable shows the development of a shield for Arduino that can interact with Scratch and replicates the

This time I’ll show how I used an Arduino to control a relay module with eight channels. Arduino in offers several advantages such as: – Open source; – Easy programming; – You can assemble your own board; – Is supported on various forums on the Internet; – Has several “shields” (facilitates the use of it

Creepy fairground attraction and Twitter App! The Psychic Hive-Mind Fortune Teller is a fairground arcade-type attraction which can tell your fortune. Even better than that though – it’s also a web-connected Twitter application that can harvest tweets and regurgitate them as fortune readings! The Fortune Teller reads the mind of a twitter discussion. It takes
