The Fritzing breadboard is very similar to the 3 earlier tasks, but with the addition of a push-button switch which is to delay output of results until required.
The push-button is tied to Ground at one end, & at the other to Digital Pin 12, which is set (pinMode) as an INPUT, & is initialised to HIGH.
When the switch is closed, pin 12 dips towards Ground, is no longer HIGH, & the software enables other tasks to be carried out - namely, the outputting of data in a suitable form.
The software for this has been modularised using Functions, so it can be tested,
& other Functions added as appropriate..
