The Walking Stick project does not perform as it should. Specifically, the buzzer sounds in constant repetition regardless of sensor distance. The Serial output shows the proper distance reading followed by a distance reading of zero. As distance is changed, the proper reading shows the correct distance but is then followed by a reading of zero.
I've confirmed the correct code and have replaced the Ultra Sonic Sensor with no effect.
What gives?
Thank you, Don

You have either some faulty components or wiring that looks good but does not make any contact. This is especially true if you are using solderless bread board.

Hi, Don
Welcome to the forum.
Please post your code, using code tags.
Can you please tell us your electronics, programming, arduino, hardware experience?
Thanks.. Tom.. 
PS. You have to assume we know nothing of your project, so you need to supply the necessary data for us to advise you.
