You have too much going on for untested software and hardware. Yank half those wires - the one going to the ping sensor, specifically. If you can't get the iPad to do anything, it doesn't matter what is in front of the ping sensor, does it?

Write a simple script that does some stuff in setup(), with NOTHING in loop(). Does the iPan react? If not, it isn't wired correctly or you are sending the wrong stuff to it.
The art of getting good answers lies in asking good questions.

Anything visibly wrong here? Did it become a hardware problem?


The soldering doesn't look very good.

Are those arrows data direction flow? In which case you have data on the receive line pointing the wrong way.

I have one of those level shifting boards. You have to power them. The HV and LV pins appear unconnected. The board has transistors on it. Transistors need power to work.
Please post technical questions on the forum, not by personal message. Thanks!
