[Is it you with the submarine meter or something? :) ] The troubleshooting "experiment" requires that the circuit should be disconnected from the SX (note the Red Xs.) Are you using a breadboard or are you soldering to the ProtoBoard? If you are soldering to the ProtoBoard, then make sure it is to the "uncommitted" pads. If you simply solder these presumed resistors in series and place that across your voltage source, totally independent of the SX, does it "divide": 1/2 across one R and the same across the other? ---------- End of Message ---------- You can view the post on-line at: http://forums.parallax.com/forums/default.aspx?f=7&p=2&m=244365#m245240 Need assistance?
