Arm Wiring

You will solder the LEDs together in series, and connect the positive end of the LED to the negative end of the next nOOd.

10Ω resistor to nOOd cathode (negative)

Positive to nOOd Anode (positive) 

Wrist Wiring

You'll solder the positive end (end with a hole) of the LED to the positive wire on the coin cell case.

Then, you'll solder the negative end to GND on the battery case.
