/* Pat McMahon -V25 - Basic Code -10,9,6,5-  19/9/2024

This is the Simpliest Basic code for a 2WD/4WD  wheel robot to wait 5 seconds, go forward, backwards,left, right, clockwise, anticlockwise, stop, then repeat forever.
in1=10,in2=9,in3=6,in4=5, Forward in2 & in4, backward in1 & in3, Left in2, Right in4, Anticlockwise in2 & in3, Clockwise in1 & in4. 
See patsrobots.com  > A050  > How to Build-Connect   for details of connections and diagrams/Info.
NOTE- You can use the code below to copy,paste, change the movements and delays, to come up with your own designed paths.
IMPORTANT- You need a clear area on the ground of about 3mx3m to run this code, so as to not hit an object and burn out the motors.
