Hello, I'm trying to make a line follower robot with a microcontroller arduino uno, im a total newbie in applied electronics, im building a robot from scratch, i need parts and tools. I found a fiew schematics online for microcontroller and motor connection i will be using 2 DC motors from a fan or something old, but now i dont know with sensor to take and what logic to use for the line following. Can you guys suggest a sensor and how to make it and how to connect it with a microcontroller. Thank you for the answer in advance
