# Calculations
## LED Formula
### LED Spec:
2.8v (forward voltage)
20ma (current)
Vsupply = 5v (Pi Power)
Vf = 2.8v (Led Volts)
R = resistor value
If = desired current
Vr = Vsupply - Vf
R = Vr / If
Vr = 5V - 2.8V = 2.2V
R = 2.2V / 20mA = 110 ohms
Make sure to add some play room, we use a 120 omhs resistor
