Hello, Everyone!
I want to use Keyence Digital Fiber Optic Sensors FS-N11CN OutPut to attachInterrupt with Arduino.
if something blocking light of sensor, that Arduino attachInterrupt will be actived.
I have made sketch like picture attached, but it didn't work.
the sensor website is this link.
Can you help me to make this sensor output connect to Arduino?
Thank everyone to read my words.
add the Output Circuit Diagram:
