Puck.js
ESP002
A Smart Bluetooth Button that can be programmed wirelessly, in JavaScript!
Puck.js is an intelligent Bluetooth button. With the Espruino JavaScript interpreter on its internal
ARM microcontroller, software can be uploaded, debugged and modified wirelessly from any
modern computer or phone, making development of embedded devices significantly easier. It has
built-in sensors, lights, infrared transmitter, GPIO, and can even control other Bluetooth LE
devices.
What makes it special?
You can get your own code working on Puck.js just a few seconds after getting it out of the box.
With Web Bluetooth you don't need to install any software on your computer - just go to
https://www.espruino.com/ide/ with a Web Bluetooth capable browser and you can connect
instantly and start writing code. There's even a graphical programming language if you're not
happy writing JavaScript.
