Hey guys\gals,
I'm kinda new in electronics, but trying to build this little project i found on the web:
I have found all the parts, except one, which I don't really understand what it is..
u can see the schematic here:
u see the 4MHz between pin 15 and 16? i know it some kind of buzzer, but I haven't found it yet.. can someone please give me the exact name of it? does the circuit really need it? seems kinda useless to me.
thanks in advance.
