I created an autofill setup for my Nespresso machine using an electrical sensor and a solenoid to control water flow.
Predictably, this setup stutters badly when filling. I need to decouple the sensor and the solenoid.
I would welcome any comment on the following.
I've mocked up this circuit (haven't built it yet: waiting on components) hoping that it will cause a long delay on start and a short delay on stop.
The sensor is closed when water level is normal, open when it drops. I'm hoping for about a 20 second delay on start and a 4 second delay on stop.
I'll appreciate any suggestions relating to design or values.
