I want to build a fuel system. I will use flowmeter also to count fuel flow speed. But I want to reset just total fuel flow. While not reset other sensor counts ( pressure, temperature etc.) how can I achieve by using a button for arduino ( code ) ? I add an example of it . Have a nice day

 

Basically you would add code to debounce a button, then when button detected
clear the flow meter variable. Google "Arduino button debounce", lots of ref
material/examples.
