radiography simlulator

[alitronic]

Good morning! I built a "simulator" for a mobile radiography unit console. To "simulate" an exposure, the "preparation" button must be pressed and held until the filament LED turns on; then a simple click on the "exposing" button triggers the emission of "radiation". The "simulator" aims to help biomedical electronics students in their imaging module. I would be grateful if you could test it (link below) and give me suggestions to enhance it, especially on the following points: 1) the idea itself, 2) does it really help, 3) further enhancements.

If only the expose button did anything.
