false beep/stuck beep

Open jschoch opened this issue 3 years ago • 3 comments

Thanks for sharing this!!!

I am running this with a 10 Ohm resistor and have tried larger. The beep gets stuck on randomly after the probe is removed from contact. Have you seen this before? i'm using ATTinyCore and the arduio IDE. Should I try to debounce it?

My circuit doesn't have a 10Ω resistor - I'm not sure where you mean. Debouncing isn't relevant, and I've never found the beep getting stuck on in my prototypes.

I wanted to have 10Ohm as the reference so test for continuity < 10Ohm. Now that I've looked at your diagram again it seems it relies on the internal pullup for the reference network?

I can't really advise on whether modifications to my circuit will work. Read the original article - it explains the design.
