Tiny line follower robot designed to use the Attiny family of ICs
This version deals with some of the short comings of earlier versions. First, thing was the readablity of the different functions, switches replaced many of the if-else statements and clear #DEFINEs used to identify what actions should occur.
The second, was a tendency for the Robot to run to fast at first. When the battery is first topped off and then stop working to early. This is due to the fact the Robot does not use a regulator in the design. The set duty cycle off the PWM to the motors does not supply enough current to keep it moving. So code was added to up the duty cycle to keep it going till the battery is exhausted. Hope you enjoy.
