Step 12: Final Assembly Wiring the Pot Both the pot and the
Arduino should have leads attached by this point, unfortunately
it isn't as simple as connecting the two sets of leads. You need
to make sure that when the screen goes up the pot is reading in
the right direction and vice versa. To do this you need to
decide which side the motor will be on when you face the screen.
Then run the app and select either up or down and note which way
the rod turns. At this point I used trial and error since there
are only two possibilities and hooked the pot up to the Arduino
using temporary connections. Now with the pot, NOT engaged in
the rod, turned all the way to what should be the up position
try running the screen up. It should ignore the command, if it
does you are good to go, make the pot connections permanent. If
it starts to run you need to simply switch the V+ and GND wires
between the Arduino and pot. Do this and test again to make
sure, then make the connection permanent. You can also orient
the motor and pot
