I have trouble about connection between IR beacon and raspberry pi.
I understand about output pins.. However, I am not sure about three inputs..
There are 3 input pin, '-' '+' and enable input.
According to manual, enable input has to be connected to 5V.
And apply 6-16V across the + and - pins...
How can I apply 6-16V across the + and - pins via using raspberry pi 2?
