I have an RSL Line Sensor which is designed to distinguish black and white lines. It detects white surface and gives me digital 1 as output, with 0 in case of black, but the surface needs to be close to it.
As it uses infra-red-sensors, I wanted to use this sensor as a proximity sensor, to tell me if there is a white surface near it. Is it possible to do this?
I think the only problem here is that we need to increase it's range of giving 1. Currently, it gives 1 only when white surface is too close to the sensors. I want 1 even if the white surface is there at a bit more distance.
Also there is an adjustable screw there to adjust something, under which POT is written. I am working with an Arduino.
