I’m writing a bunch of code for a friend’s robot, and though I have considerable experience with AVRs, this is my first stab at Arduino.
My friend’s robot has two line following sensors mounted on the front of the bot. If I use the PololuQTRSensors Arduino library, and set it up using just two sensors, am I correct in my understanding that readLine() will return a value from 0 to 1000? The reason I ask is that I only see examples for 3 or more sensors, and I don’t have the hardware to actually test it on.
Thanks in advance!
