Hello i am new to Arduino and i am currently working on a project involving using 4 MG 996R servo motors with an Arduino uno R3 and remote control I am powering the board with a 9v battery and was wondering how i should power the 4 servo motors
You will need a separate 4.8 to 6V power supply for the servos, capable of providing more than the stall current, 2.5 Amperes, per straining servo (servos and DC motors draw the stall current every time they start moving). If all four will be moving at once, 10A. Don't forget to connect the grounds.
9V batteries are for low power devices like smoke alarms, and are not suitable for powering an Arduino. They are OK for quick tests, but don't expect them to last for more that a few tens of minutes.
4xAA will power just one MG996R. RC suppliers sell battery packs that can handle four. I recommend NiMH batteries, as they are so much easier and safer to charge than LiPo.
Breadboards cannot handle such large currents, and the tracks will burn. For four servos, use a servo power distribution PCB, either commercial or DIY.
what are these battery packs called and how would i wire the connection to the breadboard?
Servo colors:
Orange = signal
Red = +6V
Brown = GND
BTW
Time to be consistent in wire colours.
Check your wiring.
You wouldn't, because the breadboard tracks will burn.
