Robot- programming the sensors

Hi, i am new the arduino world but i have a problem we are trying to get a robot to follow a black line we already have sensors but we need help on the program i will include more details soon but any idea for how to start the program?

well, just follow tutorials from the start i.e. blink program followed by analog outputs, etc.. start at beginner level and work up until u think you can handle the programming for a line trackking robot
