Arduino school project line follower robot

Hello, I got an assignment for school. The name of the project will be a robot that follows a line, and its purpose is the type of robot that autonomously follows its path. The path it will follow can be prepared with a white line on the black plane or a black line on the white plane. The robot performs this tracking process by detecting the color difference through its sensors.

Necessary materials:

1-Arduino Nano

2-3x Dip switch

3-2x 16uf capacitor

4-3x 2pin slot

5-Ams1117 3V3

6-10x 10K resistor

7-1N4001 diode

8- 12V adaptor

and PCB.
