IoT + Ethereum -- Raspberry Pi, NodeJS, Web3 & Solidity Pt1: Blink an LED on events HD

A basic led blinking example, driven by smart contract events. *Github ( https://github.com/nacmonad/eth-iot-examples/) Pre-Requisites: Node JS - https://github.com/nodesource/distributions Ethereum Test RPC - https://github.com/ethereumjs/testrpc Remix - Solidity Browser Compiler - https://github.com/ethereum/browser-solidity Web3 -- https://github.com/ethereum/web3.js 0:00-10:00 --- pi node js server 10:00-20:30 --- TestRPC and Browser-Solidity 20:30-FIN --- WEB3 and interacting with Smart Contract ERRATA: @22:22 -- coinbase is just the wallet public key that is associated with the Web3 instance. has nothing to do with genesis blocks.
