Espruino is a small computer that anyone can use to control things around them. Its JavaScript interpreter gives you instant feedback so that you can experiment and develop whatever your level of experience. Even if you've never written code before, you can still use the graphical code editor to write programs without typing a single word!
Just plug Espruino into your computer, use our Chrome Web IDE or your favorite terminal app and you'll be writing software in minutes. You can even use the Web IDE to automatically download JavaScript modules that will help you interface to hardware such as LCDs and Wireless modules.
Espruino's event-based nature means that it can save power whenever possible, drawing just 0.1mA and allowing your projects to run for years on normal AA batteries, or forever on a small solar panel.
