The value of the emitter resistor is easy to calculate: Re = (Arduino Output voltage - 0.7) / Bulb current
If the Arduino puts out 5V (are you sure it isn't 3.3 ?), and you want 0.7mA, Re is 6140 ohms; I think the nearest standard value is 6.2K -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
