You can remove the voltage line positive and negative to the circuit if you for example build another circuit and attach all the IO pins if you happen to have a program still in the chip that may conflict with the new circuit. That way the power from any IO has no place to go, unless you have a short within the new circuit of course. ---------- End of Message ---------- You can view the post on-line at: http://forums.parallax.com/forums/default.aspx?f=7&p=1&m=152765#m152850 Need assistance?
