Sensing Hot and Cold

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.

Hardware list:

• Arduino uno ( DFRduino uno )
• ultrasonic distance sensor
• LED
• resistor
• breakboard
• jump wires
• USB
