Hi all,
I wanna use 3 NIR LEDs and biasing them with Arduino according to a specific criteria I already did (see the attachment), and then I wanna receive the light by a photodiode and read its output by the same MCU.
at the same time i wanna photodiode to receive the light from each LED lonely and read the photodiode output voltage by Arduino.
so, how can I do this by Arduino?!!
