Step 8POPULATE SENSOR BOARD
Insert the 74HC595 Shift Registers into the sensor board and solder them in place.
IMPORTANT: Make sure that the "Pin 1" markers on the chips are all facing towards the "top" of the board (see picture above).
ALSO IMPORTANT: The leads of the Shift Registers will poke out of the other side of the board and form sharp spikes. These spikes are undesirable because they will poke through the gaffer tape insulation when you mount the sensor board to the crossbar. Use clippers to cut the spikes so they are flat instead of pointy -- you dont need to cut them all the way off -- just blunt them.
