As the title would suggest I'm looking to be pointed in the right direction for figuring out how to detect if a car/truck blinker is lit or not by checking for the current and using it as an input on a digital pin. I've tried looking around quite a bit on youtube, google, and these forums for the past few hours but can't seem to find anything useful.
What I'm looking for.
lamp lit > send HIGH to digital input pin.
lamp off > send LOW to digital input pin.
I'm willing to figure out the circuit myself but I cannot seem to find even a similar circuit to understand this seemingly basic concept.
