Based on the ping sensor online tutorial ( http://trollmaker.com/article3/arduino-and-hc-sr04-ultrasonic-sensor ), I've developed my arduino code with multiple LEDs. As you can see in my code, I've set up eight ranges where each one of them will light up different amount of LED, while different LEDs represent the distance range of detected object and the sensor itself. The only output we can get from it is a list of numbers, and these data will be sent over to grasshopper firefly for further development in the next stage .

Below is a video testing this code :
