[Keo-san]

We are trying to use the KoP's Gear Tooth sensors.We wired the sensor and are trying to get imput from the sensor but I get a constant 1 which is "i don't see it" I was just using a simple if then from the rc_dig_in02. I tried interupts before but since I don't know how to use them I got nothing. So I need some help maybe something I'm doing wrong with the sensor.which way to mount it and program it eventually with interrupts.please help! I'll be counting sprocket teeth with this sensor
