Looking for Piezo Voltage Warning Schematic
Hello all.
I am in search for a small simple (as in quantity of parts used and availability) low voltage warning piezo buzzer schematic. If you could provide one that would make a piezo buzzer "buzz" when voltage is too high (a high point setting) as well as too low (a low voltage point setting) that would be excellent. I have searched the NG and used good ole "google" without too much success at all. Any and all help would be greatly appreciated and I thank you in advance. Jeff |
