40 thoughts on “ Line Follower With No Arduino ” RW says: ... We usually go with one core per light sensor. That way you don’t have to worry about reading them in sequence.

At that speed, following a line gets tricky. It took the development team 8 prototypes to attain that capability. Inside the BeatBot an Arduino reads 9 infrared sensors for line detection at 100 ...

In the default jumper condition (JP:1+2), output of the infrared sensor card is at a logic-low (L) state, when it detects a black color, and vice versa. Remember, we need two identical infrared sensor ...
