hello
i'm italian, and i'm sorry for my english, i hope to be clear
i need a advice
i'm building a project and i 'd like use a transistor as a switch.
this circuit put in series or parallel two batteries. I need very low energy consumption.
what is the best transistor used as a switch?
what is the resistance value?
i attachment a drawing, in this drawing the optotransistor work when it has value 5V, but in other circuit part i need that, other transistor work when output NE555 has value 0V.someone has suggestions?
thank you in advance.
