The dual-channel motor controller is a simple H-Bridge driver chip L293D. Brain of the line follower robot is one Atmega8 microcontroller. LFR-Mechanical Assembly. First of all attach motors, clamps ...

A line follower, no way for a computer in there, and nobody could afford one either. So they were all about simplicity, until they weren’t. In 2016 when this came up, someone commented that it ...

Line Followers are a tried-and-true type of robot; both hardware and software need to be doing their job in harmony in order to be successful at a clearly defined physical task. But robots don&#821… ...

In short, U2 acts as the interface between the microcontroller (U3) and the dc motors (M1&M2) in which instructions from the microcontroller go into its input pins and the outputs are used to drive ...
