Resistor values for rocket

[gisellegk]

Calculated resistor values to use with the LEDs based on a max voltage of 3.4V for the battery. We measured current with an arbitrary resistor and calculated that the approximate voltage drop of the green, red, and yellow LEDs were 2.1V.

We calculated the blue LED to have a voltage drop of 2.9V.

The resistor value for 20mA is 20 ohms and the for the other 3 LEDs the resistor value was 65 ohms.
