Thank you @toymaker. Oops
I have been working on getting one of these sensor arrays working with a EZ-B V4. The sensor box communicates with bit-bang serial communication. This makes it necessary to use something else like a pic to convert the bit-bang serial to something usable. This is a fun project that involves a lot of head scratching and trial and error.
I used an arduino mini pro to convert the bit-bang stuff to a serial feed that says which sensors have tripped. I plan on working on this further to calculate the distance the object is from the tripped sensor(s). The serial feed is sent to the EZ-B and used to warn the robot that something is in that zone. I think that I will also set a digital pin to high on the arduino when a zone it tripped. This would give me an option to use either serial or digital to communicate with the EZ-B.
This idea came from Tony and he helped by giving me the sensor and the basic structure of the data. Without the later, I probably never would have gotten as far as I have.
