Because I want to express is that humans are the cause of global warming melting glaciers, The part of the interaction I would like to show to people is that iceberg is there, but as people come closer, the glacier will melt.Then as they go away, it will get bigger again.
Therefore I need a Ultrasonic distance sensor to detect people's distance.Use it to send a signal to the computer.
