Lab $7-$ Display a value in a Gauge.

We will build a GUI to display a value. Most display either show the value as a bar $($either vertical

or horizontal$)$ or a circular gauge. You will build a tkinter application to display a single value.

You will also provide a text field to change the value. You will also provide additional information

to add credibility to your display.

If you are displaying the indoor temperature, you should state the units and the low value, normal

range and high value

Use only the basic widget that were covered in class: buttons, labels, entries etc. and canvas

primitives like lines, rectangles and arcs. Avoid any complicated designs, that might be difficult to

customize.

Due:

See course shell.

$4.$ There are marks for aesthetics.
