Dear Friends,
I am creating a device that switches infrared signals from the device in the picture below on and off, thus sending model cars different commands at different places of the layout. I want to put the diodes in the picture on my own pcb, since I have several diodes run from the same PCB, I cannot really figure out where should they go and how many do I need. One per signal or one per signal/IR LED? Can anyone help me understand how they work and why they are there? From what I understand, the diode is a component letting current flow one way with some voltage drop and not in the other. How is that relevant for separating or perhaps merging the infrared signals into single IR LED in this case?
