Hi.
I tried to build this continuity tester, and it looks nice, but it's sensitive like a woman on pms (screams like one too). It can even detect resistance from one of my legs to the other. Is that how it's supposed to work?
Does anyone have an idea how to change it's sensibility so the sound deteriorates more with a greater resistances?
Or maybe a different schematic that could fit my box, and has been proven working?
The only difference that I made in the circuit was using a buzzer with a 47 Ohm resistor.
EDIT: And yeah, funny thing is, the bigger the resistance the more it screams.
