I need 3.0V to run a motor; it has to be constant so the motor will run at 5 rpm. I looked into a voltage regulator but I can't find one that brings it down to 3V only 3.3V. So I tried two 1N4001 diodes with a 3.3V regulator to bring it down to very close to 3.0V, but for some reason the voltage was fluctuating between 2.8V and 3.1V; so that won't work because the voltage fluctuation will change the rpm of the motor. I also tried a voltage divider circuit with the 3.3V regulator because I was desperate, and like I thought the motor stalled. Do any of you have any ideas, or is there something I overlooked?
