It can only go a certain direction when active. Do you have any suggestions as to solve the problem to make it turn rather than chase its tail? I am using a Dual Comparator LM393 and I do have a Quad comparator (LM339) just in case.
Schematic location (it isnt the schematic from the book, but it is the same thing)
