Hi Folks,

You are correct. You cannot turn off the LED for the Modern Robotics Optical Distance sensor. The sensor pulses the light on and off so it can try to cancel out the effect of ambient lighting (as Philbot noted).

In our testing, we have primarily used this sensor as a reflected light sensor (line following, etc.). It can also be used as a distance sensor, assuming you know what the reflectivity is of your target surface that you are measuring your distance from.
