The Arduino is an open source microcontroller development board that makes it easy for beginners in electronics to do crazy things. We are going to be continuing our Intro to Arduinos talk from Phreaknic, Anyone new to Arduinos should watch that talk online. We will be discussing building your own devices to interact with the real world: making electronic musical instraments, wireless communication, networking Arduinos, controlling lights and sounds, sensing touch, RFID, building custom games with custom controllers, sensing temperature changes and ways of notification like phone calls, sms, hidden buzzers. We will also go into building clothes with embedded electronics.
