Introducing Serial Monitors and Serial Inputs:
Our serial monitor user input simulation for IOT/Smart Cities is at
http://www.goo.gl/YywL6V (With the Arduino serial monitor open, type f for fast blink, s for slow blink)
Our related project for rush-hour / regular traffic light is at https://goo.gl/EeidwC
Our ultrasonic sensor for Servo motor or LED operation is available at https://goo.gl/iaVnaM
(at close range, an LED comes on and the servo moves, as an office building door unlocking)
