As aforementioned, I have a L14F1 phototransistor. I am using this in a DC circuit.
A stupid question it is. Please take it seriously however. Read carefully; I repeat: how do I make a switch in a DC circuit using a L14F1 (3-pin) phototransistor?
And coming to why I don't use a 2-pin phototransistor rather than 3-pin, the cause for it is that there is nowhere I find 2-pin phototransistors.
Please post a diagram if possible, illustrating the circuits.
Note: Please don't tell me any locations or websites to find a 2-pin phototransistor
