    Hello everyone,

    Can someone tell me what this electronic symbol is in this link:

    The symbol I need to know is the one that looks like a NPN transistor except it doesn't have a base input line and it receives light. I'm trying to make this:

    by buying some of these stuff from digikey:

    Also, what is that resistor looking thing that has the square or zero character on the board?


    Thank you.


    EDIT: Nvm, it was a phototransistor and a short circuit 0 resistor.
