I'm making a piezo siren with motion pir sensor. I soldered the siren part and no noise so I guess I scrapped little flux off to get it working, that's really  bizarre. It's very sensive. Lol. I put my finger barely on the contacts, it changes tone.  I'm ready for soldering the rest of it for the motion part. I also love the 555 timer, but I'm not used to using it as much.

Interesante en que podria utilizarlo

Yeah piezos are super sensitive- delicate too. Don't crunch the wafer!..

True. Lol. It's actually not a waffer, it's a black mini piezo surface mount speaker. I do have some of those waffers, they are ultra thin.
