this is robot which follows black line on white surface
Step 1: IR Sensor
An infrared sensor is an electronic device, that emits in order to sense some aspects of the surroundings.
it gives digital output 1 and 0
when the object is in IR sensor range then it gives "1" else "0"
also when white body is present then it gives "0" and black body gives "1"
Step 2: IR & Motor Driver
Step 3: Connect IR to Car Frame
connect ir on robot frame and connect wire wire
Step 4: Motor Driver
connect motor to motor driver
Step 5: Arduino Pin Connection
