line follower using arduino uno
TRANSCRIPT
Line follower is a machine that can follow a path. The path can be visible like a Black line on a white surface.
In smarter versions of Line Followers, The path can be invisible like a magnetic field.
Description
Chassis , Castor wheels , Atmega328P Microcontroller, Color Sensors, D.C. Motors, Connecting Wires, DC source.
Components Used
There are cases where smarter versions of line followers are used to deliver mail within an office building and deliver medications in a hospital.
The technology has been suggested for running buses and other mass transit systems, and may end up as part of autonomous cars navigating the freeway.
In a warehouse where the robots follow 'tracks' to and from the shelves they stock and retrieve from.
Automated cars running on roads with embedded magnets.
Technology
We used strengthened paper to build the chassis of our Line Follower.
2- Building Line Follower Chassis
Finally
Both motor circuit and input circuit are assembled together, with the Arduino microcontroller, it works as the following :
3- Assembling
1st configure the pins of Arduino
Code-language used : Arduino C
2nd configure sensors and analog read
Code -Logic Part
Simply : we use 4 sensors : far left , left , right , far right
Code in following slide
