Our new course on Bitcoin, Blockchain and Decentralized technology gives a crash course on Bitcoin and many other blockchain projects, like Ethereum, MakerDao, IPFS, SlockIt, the DAO, Zerocash, and more. There are demos on how to acquire, store and use Bitcoin, including web, hardware and paper wallets. Some of the latest topics in Bitcoin are also covered, like soft vs hard forks, segregated witness, the lightning network and more.
This project shows how to send SMS text messages to a cheap scrolling LED display via an Android app and arduino with USB host shield.
The project was originally inspired by a friend wanting to make a “sexting themed” costume, with a scrolling LED display of live texts sent from people at the party. We found a $13 LED belt buckle online, which looked cool, but only had a few buttons to manually enter in messages. A couple wires and lines of arduino code later, we were able to automate entry of messages. Continue reading “SMS to Cheap Scrolling LED using Arduino USB Host Shield and Android App”
An iPad app that provides augmented reality steps for building a circuit on a bread board. Graphics are overlayed on the actual breadboard to show you exactly where to put parts, and provide extra information, like values, tolerances, and voltages.
