I've got a motor that's driven by a 1.5V battery. The shaft turns slowly and that's the way I'd like after replacing with a USB cable (5V) source.
In the current circuit there's no resisters (just a diode) - so using ohms law - not sure what the current draw is. It's V/0 right? Infinity?
If I can find the current draw - I plan to use 5/I to add an appropriate resistor and I should be good to go - right?
Please help the nube boob.
