Power DC Clock Motor with Arduino Nano

I'm brand new to using Arduinos for anything and have embarked on what seems like a simple enough project to get my feet wet. I'm making an analog desk clock with an LED backlit face. The LEDs are RGB and Im using pots to adjust the color mix and the brightness and I've got that working fine so far.

I'm planning to use a clock motor that's usually powered by a single AA battery. Since I'm going to be powering the Arduino Nano with a 5V mini USB cable anyway, I figure I can power the clock off the Arduino. I know I'll to get 1.5 volts of DC power to the clock. How do I go about doing that?

You could tap power from the 3.3V pin, then put 3 1N4148 diodes in series, that would drop about 1.8 ~ 1.9V, leaving 1.4 ~ 1.5V for the clock motor.

Thanks, I’ll give that a go!
