For my Blink Project, I created display to show the distance and simulate heart beat as two people come closer together. This is meant to be a visual representation of when to people in love come into close contact with each other.Using two ultrasonic range finders to determine the users position, LED's would begin to blink. There is a total of 6 LED's connected to the arduino; three per ultrasonic range finders.
Once a person comes within range, the outer LED begins to blink. It blinks at roughly around 70 beats per minute to simulate a normal heart beat. As the person comes closer to the sensor, the first LED will stop blinking and the next LED will blink. The frequency of the blinking increases as based on who close the person is. Once close enough, all the LEDs on connect to the corresponding sensor will blink at an increased rate to simulate nervousness or excitement to see or be around the other people.
