Added this description:

Hello, Puck! demonstrates many of the built-in features of Puck.js.
Like Arduino, you can use Puck.js to build IoT devices. While you code
Arduino in C++, Puck.js runs JavaScript. Like the Amazon Dash, you can
program behaviors accessible with a single button click.

• Web Bluetooth IDE and console • Button • RGB LEDs • Temperature
sensor • Battery sensor • Magnetometer: movement, orientation,
magnetism • Nearby BLE devices • Light sensor • NFC URL broadcasting
and field detection
