Step 7Insert and Connect the Analog Multiplexer
Solder wires to short the S3 and S2 pins to the GND pin of the multiplexer. We only plan to use the first four outputs (for the four bend sensors), so we want the multiplexer's upper two select bits to always be 0.
Also short the SIG pin to the VCC pin. We'll use the same 3.3V signal to run the multiplexer and as the input voltage for the bend sensors.
Connect the first four multiplexer outputs (C0, C1, C2, C3) to the inputs for the four bend sensors on the cut palm board. I suggest using a ribbon cable for this, and try to maintain a sensible order -- the traces on the palm board are labeled with the fingers that they connect to. I used:
C0 -- Thumb ("T" on palm board)
C1 -- Index Finger ("I" on palm board)
C2 -- Middle Finger ("M" on palm board)
C3 -- Ring Finger ("R" on palm board)
Connect the remaining two select pins (S0 and S1) to two of the wires in the bundle that connects the palm housing to the wrist housing. I used:
S0 -- White
S1 -- Peach
Finally, connect the VCC and GND pins on the multiplexer to the VDD and GND pins on the accelerometer.
