Functionalities Stand

In the support for the button we have also included a Arduino board on which is connected a buzzer, 9 leds and a Ultra Sonic Sensor. The purpose of this is to detect the approach of the people around and brighten up the support to catch the trespassers attention.

The distance range of the Ultra Sonic Sensor is set maximum to the 45 cm by default. For our installation we need at least 1 m. To fix this problem, I have found some tips and ideas regarding this topic by searching on forums & tech websites (EX: http://www.instructables.com/id/Improve-Ultrasonic-Range-Sensor-Accuracy/) .
