Ohh ok

I get it

So if I want to change the range to about 6 inches would that be done by changing the resistance to the IR leds?

That web page said "approximately 15cm". I had to use an on-line calculator because I am an old phart, and it said almost 6 inches (5.9").

Techbuilder,

How about:
You order the Sharp IS471FE and start the program right away, while you are waiting.

You can substitute a switch.

When the IS471FE gets there you can just add it.

This is actually a good way to build and test as you go.
