Capacity for AAA battery: 860-1200 mAh at 1.5V
x 1.5 = 1300-1800 mWh
Max power dissipation for each LED: 120mW
Each comma has 10 LEDs, so 10 x 120mW = 1200mW
All three commas = 3 x 1200mW = 3600mW
3600mW / 1500 mWh (taking average) = .42 hours = 25 minutes
Ignoring the power to the Arduino and loss in the conductive thread. :)
How long will the battery last?
