  • The SDA and SCL inputs of the sensor’s two wire interface specify a voltage limit of 3.6 volts (+/- a bit) and (if I’m correct) the outputs of the arduino duemilanove are at 5 volts; do people usually accomplish this voltage drop with a voltage divider or an op-amp, or is it even necessary?

No public wish lists :(
