I have qtr 8rc sensor, But i couldnt read the values from it.
How can I test my sensor? I connected vcc and gnd.
each sensor outputs are connected to a led.
When i pass the white or black thing on sensors, i see nothing change in the leds.
Also I have tried doing this with ardino. Result was the same. I read values 0 0 0 00 0 00 0 0.
sensor outputs to aurdino digital pins (3-10). I used example codes.
Please help me…
