Hello,Greetings for the day. Does qtr 8rc support analogRead in Arduino . Does it gives calibration values between 0 and 1023
Hello.
No, the QTR-8RC is designed to provide a digital I/O-measurable output, so it is not meaningful to use analogRead() with its sensors. You can read more about how the QTR-8RC works in the QTR-8A and QTR-8RC Reflectance Sensor Array User’s Guide, which can be found under the “Resources” tab on its product page.
We also have an analog version of that sensor, the QTR-8A, that can be used with Arduino’s analogRead() function.
