    Hi there,

    I am trying to make a line following robot that steers with one servo motor attached to a wheel in the front of the robot. How would I go about making this one servo turn according to what the sensors see? I will start out using 3 of them.

    I was thinking of something that basically says if the outside sensors read white, servo should be at 90degrees. If the left and middle read white and the right reads black, servo should be at 65degrees, etc. The only problem is I don’t know how to code this!

    Also, I don’t see in your code where you specify what pins the sensors are connected to. Isn’t that necessary??

    Any advice is greatly appreciated 🙂
