Click / Touch the disc and drag it until the arrow. When the number reaches the arrow, it will turn red, then let go and that's your number.
Include the RotaryDial.js file.
<script src="RotaryDial.js"></script>
Then create a new RotaryDial
const rd = new RotaryDial();
Creating a callback is easy, just define what your function will do with the number it receives from the RotaryDial.
const func = function(number){
alert( number )
}
const rd = new RotaryDial({callback: func});
By default the RotaryDial has the console.log function as the callback.
The RotaryDial accepts a configuration object on its constructor. The most import parts are the size and the callback. The size will determine the size of your rotary dial menu, and the callback determines which function will be called when a number is selected. Besides that, there are some color configurations you can fiddle with.

callback - The function that will be called when a number is selected. Default console.log

circlesFillColor - The circles (where the numbers are displayed) color.

textFillColor - The text color.
