Buzzer is 6V if your supply is 6V ...Bryan good day!<br />Buzzer is 6V if your supply is 6V and 12V buzzer for 12v supply. <br />We have 3 versions of doorbell circuit, the first is using a buzzer and the last one is using speaker.You can use only a speaker using the last circuit above.. Replacing speaker instead of buzzer may cause the circuit not to work.. <br />tnx.DH-gmhttps://www.blogger.com/profile/16906779443966743177noreply@blogger.comtag:blogger.com,1999:blog-8622007552114030374.post-41170214864688595632011-03-27T23:07:19.885-07:002011-03-27T23:07:19.885-07:00How many volts for the buzzer?
