Fritzing will also be useful when you hand the project in. You can print them out and use them in your report, or on your presentation boards or ppt shows.
It's easy to use- there's a library of standard stuff including what you need: breadboard, servos, batteries, wire etc.
But if you're pushed for time, draw the circuit on paper and take a pic of that to post.
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.
That's a shame... suggest to her that every home should have one anyway, and it'll be a home item not a science item. 8)
Btw, your Fritzing diagram the other day showed you had the power hooked up with + and - reversed... I hope that was a mere Fritzing error not a real error? I've never hooked a servo up with the polarity reversed, but I suspect it's bad for it.
