schematic missing information

[SnippetsUnlimited]

The schematic shows use of a transistor for the buzzer but there is no transistor number mentioned on the schematic. Can you suggest the transistor number/model used and the pin connections. I am just a hobbyist and do not have knowledge enough to know by myself, what kind of transistor I should utilize here.

Thanks-

You can use PN2222 or something similar (n-p-n).

I do not have PN2222 available but but it seems that I can use the available alternative 2N2222.

Thanks for the help!!
