Puck.js is a low energy smart device which can be programmed and debugged wirelessly with JavaScript. It is both multi-functional and easy to use. This beacon uses a custom circuit board with the latest Nordic chip, Bluetooth LE, Infrared transmitter, NFC, magnetometer, temperature sensor, RGB LEDs, and much more. Unlike other beacons, Puck.js comes with the open source JavaScript interpreter Espruino pre-installed, which makes it incredibly easy to use. Anyone without any prior programming experience can get started in seconds.

Features:
Puck.js has various sensors for different purposes and various kinds of output components. It can measure light, temperature, magnetic fields, and capacitance. This beacon also can control Infrared remote devices, produce any color light using RGB LED, and has a tactile switch that turns the Puck into one big button.
The Magnetometer on Puck.js is a digital compass. You can measure its orientation about the earth’s magnetic field in 3 dimensions. It can also detect a magnet nearby and measures the magnetic field.
Puck also has the Web Bluetooth feature that enables controlling it from a web page wirelessly. The website simply sends the JavaScript code directly to the Puck, and it’ll be executed. Another excellent feature of Puck.js is internet accessibility. Espruino contains TCP/IP and HTTP client and servers (including Web Sockets). With a suitable Bluetooth LE to the Internet Gateway, you’ll be able to put your Puck on the web!
