Examples

Here I will give you some examples for using this package. The main method is:

 display(temperature: number, frame: boolean)

In the first parameter temperature, you can give a number what the temperature should be. In the second parameter frame, you can the method you want a frame (true) or not (false).

With border

An example command

display(12.34291, true)

The output

 ________________________
|     _    _        _  _ |
|  |  _|   _||_|   |_||  |
|  | |_  / _|  |      |_ |
|________________________|

Without border

An example Command

display(6, false)

The output

  _     _  _     _  _
 |_    | || |   |_||  
 |_| / |_||_|      |_
