purchased sen-09299 Photo interrupter.
New to everything.
followed a diagram and can’t get the interrupt to work.
trying to get it to work on breadboard with redboard before I make final things final.
can anyone give me picture of one setup on a breadboard ? Maybe I would be able to determine what I am doing wrong.
I have attached a pic of what I have setup… I am lost and confused…
It can’t really be this hard… can it???
any assistance would be appreciated.
