I use Superchart Datastream from 2 Sensors (Arduino Uno per USB Connection)
I need Plotting only 60-90 seconds (in Full Screen Modus!), then I will the Datastream stop and es Graph to analise.
How can I stop the Datastream? I will the Graph further on Screen seen.
And How can I start it?
I need a sketch?
I would prefer to Start/Stop with a Button. Is that possibly? Like a Recording Button or similar:)
My Project is an old Lever Espressomashine to “digitalize”
