There are two items that I’m confusing.
They are PHOTO DIODE & the PHOTO TRANSISTOR.
The wikipedia doesn’t tell about the medium they travel.
What I want to know is PHOTO DIODE/TRANSISTOR does it sending & receiving IR beams or some other medium like light etc.
Please explain this very simply.
Thanks
