AdjusterJan 13, I believe soldering shouldn’t be much of a safety concern as I have used them before and have gone for a robotics class wherein we had to solder the parts provided onto the provided PCBs in a way, they didn’t explain how they work, but just doing the soldering. AdjusterJan 15, No, create an account now. Jan 12, 4. I suggest that you look phototrsnsistor that because amongst other things it will show you how to connect the device up correctly.

Using a L14F1 IR phototransistor in a switch | Physics Forums

And never mind the time, my parents decided to buy photktransistor phototransistor later. I just suggested a remote control car with it, but I could rather make a simple wireless circuit switching a bulb off and on. Like the earlier one I posted, why couldn’t I just leave one pin left out hanging? Jan 15, Secondly, I don’t want to make more sensitive arrangements, for I can easily afford to point the laser pointer on the phototransistor, even if impractical.

Last edited by a moderator: I believe it is the pin that juts out a little bit, which should be the base pin I have marked my guess in the photo attached. Jan 12, 5.

Join Physics Forums Today! In another posting I also sent you a link to a data sheet for the L14F1.

L14F1 Phototransistor

My father told the transistor may fry up at excess voltage, but is it right? This was exactly why I asked a circuit diagram. By the way, could you tell why the resistor is used in photoyransistor circuit? You will see that the transistor base lead is not connected, as was suggested in one of my earlier posts. I would guess that by 3-pin you mean a device which has the base connection brought to an outside pin, since LIF41 is a photo-darlington which has the input base brought out?

Do you already have an account? As a final help, in the picture of the phototransistor product I have attached, please look at phototrxnsistor and re-post it to me if you can identify the base pin.

Jan 13, 7. This would help against leakage effects and improve turn-off speed, at the expense of lowered sensitivity.

Your name or email address: Hello univeruser Since you have said that you don’t want to make any more sensitive arrangements, here is a simple diagram adapted from what you originally uploaded, showing the photodarlington transistor driving a LED – in this case, the ohm resistor is needed.
