NOTE Current from the analog outputs can drive a 20 mA device. To use
an analog output for this purpose, you may need to add a 1/2 watt
resistor in series with the device to achieve the required total resistance
of 500 Ohms. For example, to drive a device that has 100 Ohms of
resistance, wire a 400 Ohm resistor in series with the 20 mA device to
achieve 500 Ohms resistance.
