It all started when I saw this post on Lifehacker.com to make a “Snail Mail Notifier for your Smartphone”. The post is about making a iphone sms push alert that would let you know when someone opens your mailbox (to deliver mail etc.). The video tutorial originated from Make magazine. It talks about this micro controller called Arduino.
“Arduino is an open-source electronics prototyping platform based on flexible, easy-to-use hardware and software. It’s intended for artists, designers, hobbyists, and anyone interested in creating interactive objects or environments.” via Arduino.cc
