Hello everyone , im having a question about this type of battries . is it safe to use it for arduino project
my project contains 4 6v motors and arduino uno and arduino motor control shield and micro servo 9g motor
will it damage my parts or it is safe . thank you for helping out
If you use those batteries in series, they may destroy the servo. Always check the manufacturer's ratings.
You need a stepdown regulator to power the Arduino (5V or 3.3V as required).
It is best to power motors/servos separately from the Arduino, as the motors create electrical noise that can damage or reset the Arduino. If you do, don't forget to connect all the grounds.
