Step 2)
Take a Female to Female single wire jumper and connect it to the Arduino Reset on plug JP4 on the
WatchDog Timer board (see picture).
Step 3)
Then connect the other end of the wire in Step 2) it to the 3rd to the left most pin on the second row of
the male pins on the Mini Pro LP Arduino board (Part I). See the picture below to get it right! This is the wire
that is connected to the WatchDog timer board. If the WatchDog timer is not patted by the Arduino periodically,
then the WatchDog reboots the Arduino Mini Pro LP. This makes sure the computer doesn’t get lost and
powers up correctly regardless of the funky way the power comes on from the solar panels. :)
