Angular Component To Choose A Value Using A “knob-like” Rotation Button

knob is an angular component to adjust values with the control of the typical handle (for example, very used in music devices).

The component is very essential, you only need to form the acceptable values and the degrees that the handle can manage.

How to make use of it:

Installation:

npm install ng2-knob --save

1. Using the handle tool is very simple. First, import the component within the angular application unit, such as this:

import { KnobModule } from 'ng2-knob';
...
@NgModule({
 ...
   declarations: [
        AppComponent,
        ...
    ],
    imports: [
      BrowserModule,
      FormsModule,
      KnobModule,
      ...
 ...
})
export class AppModule {}

2. To start working with the new component, add it to the HTML part of the component you want:

@Component({
    selector: 'my-app',
    template: `
  <h3>Knob Use Example</h3>
    <div class="container">
        <knob class="skin1" #myknob1 [min]="10" [max]="200" [value]="80" [startDegree]="200"  [endDegree]="120"></knob>
        <div class="info bpm">{{myknob1.meterValue}} bpm</div>
    </div>    
  `,
})
export class App {
    // ...
}
