I'm working on a project that involves a turret controlled by a servo motor using a microbit. The issue I'm facing is that while the servo operates perfectly when the microbit is connected via USB, it doesn't work at all when I switch to a battery pack. I'm using two 1.5 volt AAA batteries, which keeps me at the 3 volt limit for power in my project. When on the battery, the servo just hums slightly but doesn't move. I'm really running out of time as my project is due in two days, so any suggestions would be greatly appreciated!

It sounds like 3 volts might not be enough for your servo motor. You could either check if a different servo with lower voltage requirements might work or consider using a voltage booster to increase the power supply without exceeding your project limits.

I haven't heard about voltage boosters before. What exactly do they do? I'm going to look into getting another servo, but I'm not sure if that will solve my issue.
