The following code is @dave1707 code , I need help on it to allow the INCREASE or DECREASE of values for fixed predefined TIME (ex: 1 minute, 90 seconds, 120 seconds, etc …) otherwise a possible use " I want to get a Number of 1200 cpm(read count per minute) while performing à measurement of radioactivity decay of à source during à fixed Time".
Is it possible to embed a font that simulates a real counter.

I am amazed by the amount of code you can produce and share every day!
