and it requires a 2n7000. So i went to the local electronics store and I asked a 2n7000 but they didn't have one, although it is widely used
I did a small search in order to find a replacement for the it and I have ended up on those:
2n2222 /2n3904 / MPSA13 / BC547CPHIL
I am not sure if they can be used instead of the 2n7000 in this project! If you have any other sugestions please point them out!
