Qtr-8Rc Reflectance Sensor Array Arduino Code
Qtr-8Rc Reflectance Sensor Array Arduino Code . The code for the arduino line follower robot is available in arduino ide as well as atmel studio. Qtr 8rc reflectance sensor array arduino code. Problems with QTR8RC Sensor Sensors Pololu Forum from forum.pololu.com With this line of code, the sensor array will return the position of the black line. The rc array uses an rc circuit and capacitor decay time to determine a reflectance amount whereas the a array uses a voltage divider to determine a reflectance amount. The phototransistor uses a capacitor discharge circuit that allows a digital i/o line on a microcontroller to take an analog reading of reflected ir by measuring the discharge time of the capacitor.
