Hello . I am building maze solving robot where I am using pololu qt8rc sensor but the main problem is that when I connected my Arduino mega to serial output pin for checking the values it is showing all 8 values as 0 and the sensor is also placed within the descriptive range(3mm) .please help me
Hello.
Could you post some pictures showing all of your connections? Could you try running the QTRRCRawValuesExample.ino example from our Arduino library for the QTR reflectance sensors and posting a copy of the output you’re getting? You might need to make some minor modifications so it uses the same pins that you are connecting to.
