Triggering littleBits LEDs with Node.js Using Johnny-Five

LittleBits is an open-source library of electronic modules that can be easily snapped together with magnets, offering over 60 modules and more than 150,000 possible circuit combinations, making it a versatile tool for learning electronics and prototyping ideas without requiring programming skills. However, it can be integrated with Arduino and programming through platforms like Johnny-Five, a Node.js-based IoT and robotics framework. The text details a project where littleBits is used to connect Twitter's data stream to an LED module, causing it to blink when specific tweets are detected, utilizing tools such as the Arduino at Heart board and PubNub's Twitter Firehose. The process involves setting up the Arduino with StandardFirmata via the Arduino IDE, installing Johnny-Five and PubNub modules, and writing JavaScript code to manage the connections and data flow, with the complete source code available on GitHub for further exploration.
