This Robot will follow a black line that is 1.5cm to 3cm wide. Here we do not use any Microcontroller and Motor driver IC's. so this project is pretty simple. You can Download the Designs from here. Download Steps to follow  Download the design files and extract with winrar.   After the extraction you get 3 PDF files PCB Layout and Circuit Diagram. Print the bottom PCB Layout in actual size A4 using Laser printer on a photo glossy paper. Then Make the PCB  and Assemble the components as per the Circuit diagram and PCB Top Layout. Solder it well and wire the Circuit board to both Motors  Adjust the sensor sensitivity by adjusting the 10k presets on the PCB. left preset for the Left sensor and Motor and Right preset for the Right sensor and Motor. You can use black and white surfaces to adjust the sensitivity to the threshold point. The threshold point is the Motor barely start's rotation when the sensor on white surface and suddenly sto...
