Hello.
I'm making a gun from a videogame for a consume which has a motor, lasers and LEDs.
The LEDs and lasers are 3v
The motor is 4.5v (though it will turn at 3v)
The torch on the side is 4.5v too.
Is there any advantage to using 9v battery with resistors in place rather than using a voltage closer to the required voltages? Will a 9v last longer?
Also I have no idea how many milliamps the motor is drawing so I'm unsure which resistor value to use.
Any help would be much appreciated.
Thanks.
