hello ! i am working on a line follower robot. I bought a QTR-8RC reflectance array sensor for this purpose. While working with the sensor i noticed that sensor number 7 and 8 of my array doesnt seems to give reading properly. I first thought there might be some problem with my code so i tested it with the QTR-8RC raw data value code from the arduino examples but still the problem REMAINS. I bought another sensor but it still give reading of only the first 6 sensors but sensor 7 and 8 are still not working properly. Please HELP !!! As i seems to have run out of ideas.
I am using Arduino mega 2560 (although i have also tried with uno) and i haven’t split the sensor.
