i trying to use arduino nano to control several servo motors(MG90S) but i am not sure whether it can works? In addition, i would like to use battery to operate the arduino board and the servo motors. please advise me on this. thank you very much.
Yes both are completely normal things to do with a Nano. It will work if you choose the battery carefully. You should power the servos directly from the battery and not try to power them through the Arduino.

Do I need to add motor shield? I did heard about this and not sure about it
Yeo:
Do I need to add motor shield?
No you don't. (Which is a good thing, since I'm not sure if there are shields to fit nani.)
What if I Want to operate the servos with Bluetooth? I just need to buy HC-06 blutetooth serial module and attach together with the arduino nano. Will it work?
Well you're going to need something that will send commands to the HC-06 and you'll need to write some code to interpret the commands and run the servos but it all sounds fairly straightforward so far.
There must be hundreds of working projects out there with Nanos running robots or remote control vehicles with servos controlled via Bluetooth.

You'll also need a source of BT, like an app on your phone or whatever, to send the commands.
Have a look at this for instance. He shows it toggling an LED, but all that's happening is that the Arduino gets a 1 or 0, and uses the 1 as on and 0 as off. So that could easily be the signal for your servo to say open and close a lock with servo.write() rather than a digitalWrite() for the led.
Or the other end of the scale is this guy's all-singing, all-dancing BT control panel.
Thank you so much. If I have any queries I will seek help again
i am totally new using arduino, sorry for that.
Is there a code that able to control 3 servos in different direction using one arduino uno board?
