This is the weekend project of maker.They called it Hot and Cold .It used little more than an ultrasonic distance sensor, an Arduino board, and some common components to build a basic circuit. Then use software loaded onto the Arduino to explore three different experiments with the same circuit: a proximity program that glows “hot” the closer you get to the sensor, a motion-based game, and a distance trigger.This is useful for beginners.Chenk the below video,you will get something.
