Bear that in mind once you have it correct and it still doesn't work.


Unless of course (as I hope) it was a Fritzing transcription error not an actual error....

Is six batteries too much power for the servo motor? I'm using 6 lithium ion batteries instead of 4 AA's in the tutorial.

You need to be more specific than that with a question: what voltage do the servos require?- usually 4.8 to 6V but check the maker's specification sheet. Then what voltage do those batteries provide... then you can answer your question yourself. I hope you have a meter, and can check the voltage of the batteries? If not, you really really need one for this kind of work

The word "power" has a specific meaning and is volts x current (amps), although I suspect you mean volts. As long as the current the battery can supply is more than the motors require, and the voltage is in the range required, you should be ok.

Battery provides too high a voltage and boom.
Battery provides too low a voltage and probably motor wont work.
Battery provides too low a current and I'm not sure... might damage the battery by trying to draw too much, dunno
Battery provides too high a current, no problem because devices only draw what they need.

Yes but you have them in a holder thingy according to your photo-1 from the other day. That will connect them + to - inside the holder, known as "in series" and the voltages add up. So that thing will be putting our 6 x 1.5 = 9v nominal.

It may even be more, if those fresh batteries are more than 1.5 out of the packet. So yeah, you may well be putting too many V's into the motor.
