I notice that the LED on my board is very dim. I’ve taken readings from the sensor with target media 3-5mm in front. But with the provided LED I have to jack the gain up to it’s highest value to get any signal. It works fine with brighter light sources.
I’m trying to figure out if:
(1) My LED is busted
(2) My sensor is busted
(3) I’m screwing up calibration
(4) Everything is normal. I just need more light
Any help would be greatly appreciated. Thanks!
