Question about basic stamp board

sejasti123

Hi, I'm new to basic stamp and I like it. I have a question about the basic stamp board.
Is the basic stamp board very sensitive to low currents?
Link of the video with what happened.

The code that is loaded, is the incremental encoder of parallax. And use pins 0-1
If I designate the pins low, this problem does not happen.

Yes, as with almost all micro's it is sensitive, particularly when the pins are floating (not connected to anything). A resistor between the pin and ground or V+ will solve that problem.

The bread boards are pretty capacitive. As kwinn mentioned, a pullup or pulldown resistor on the input should alleviate that.
