I am trying to set up a simple (so I've been told) circuit for detecting an IR beam.
I have:
an SFH 5110-36 IR detecting phototransistor with an amplifier inside
an IR LED
a power source
some resistors
I'm not sure what the proper configuration should be. I'm fine for setting up the LED to turn on. But I don't know what gets connected to each of the 3 prongs of the transistor. I believe i should be able to measure the 5V output from the middle prong. ground is connected to one of the outer prongs, but what about the 3rd prong?
do i need to connect anything else on the outside?
I know barely nothing about circuits and terminology, so if you're kind enough to help, imagine you're explaining it to a 3rd grader. I'm smart, but still learning.
thanks,
