How could i avoid using a mosfet?
i couldn't find one, so could i just make one or something or maybe use a transister from something else? im doing this project:https://www.instructables.com/id/S13U2RLFRTXG8EP/?

try it with a transistor...looks like it needs an NPN transistor - something tells me the piezo has some kickback that could cause problems - but try it!
