Can QTR-8A be used with Arduino UNO?

It looks like it uses eight analog inputs, while the Arduino UNO appears to only have six analog inputs.

Does this mean it cannot be used with the Arduino UNO?


You can still use the QTR-8A with the Arduino Uno, but since there are only 6 analog channels on the Uno, you will only be able to read 6 sensors. If you want to use all the sensors, you might consider the Arduino Mega. It has 16 pins that can be used as Analog inputs.
