Reed switch help - oooopic - Aug 11 16:10:53 2008

Hi,

i was thinking that i could build a speedometer
using the ospeedometer-object.
I have the reed-switch, but how big resistor should i use?
I found one 150 ohm and one 20 ohm, so is 170 ohm enough?
It should let trough 29 mah on 5 volts..

Thanks
