Newbee: Optocoupler to BasicStamp

I am new to all this stuff an could use a little help.


I am trying to determine the state of a MOC3010 Optocoupler using a
BasicStamp.

I have tried both reading the pin state as well as using the POT command to
read the resistance of the 3010.
I have tried pullup and pulldown (10K) resistors.

Could someone help me design a simple interface circuit to read the state of
the 3010?

Also, I want to power the LED portion of the optocoupler from the computer
USB port. I have been using a 100ohm resistor. Is this a good value to use?

Thanks for your help
