Arduino | Powering Multiple Servos and Motors

How to power multiple servos and motors with your Arduino, and how to avoid the pitfalls of plugging everything into the 5V pins.

Thanks for this video. Very useful, reinforcing my understanding. But just a warning: We should be VERY careful plugging in our USB connection between Arduino and computer WHILE ALSO connecting external power to the Arduino barrel connector. Some Arduinos are spec'd for much higher external voltage than the 5VDC USB standard and we would hope that they would maintain the 5 V on the USB power channel ... but this isn't a perfect world and spikes may occur which can damage your computer. I fried a motherboard on my DELL laptop doing this. A week later, being careful to avoid having both USB and external 11 VDC plugged into to Arduino Mega, but did something slightly different and my DELL laptop once again shut down for several days. Best wishes.

You literally helped me solve a massive issue in my project, the crackhead engineering community thanks you my good man! You’re the best!

Thank you so much for the video! This was rhe first time i saw some powering servos and the ardunio separately

Can we use smps, or power supply unit rather than battery?

[alexanderredhead]

What if I use a power supply per servo? Do I just connect all grounds together? And would I connect the positives together between servos and power supplies or keep them seperate?

Thank you I wish I had seen this the other day before I damaged my attiny88

[mikeythemodelingman]

How do I determine how many volts I need from the external power supply if I were to add more servos?

Hello so I am making a drone from R6 and I want to power two different motors on each side. How would I do this without a breadboard since it has to be compact. Is there another way?

[MrZeRoEvEr]

Very informative habibi, thank you very much.

If i have an esp32 and i am powering it with 3 lithium ion batteries connedcted to a voltage regulator l7805 which is then connected to the vin and the gnd
So should i connect the 2 servos like u did to 3 li ion batteries and then connect the ground to the other gnd in the esp32
Will that ruin or blow anything?

[PulseRBX]

the problem is the arduino board has a onboard regulateur that limites how much amhp are going through soo your not getting 2 amp by using the adapter the arduino is getting only around 500 maph

[mydrouno]

Thank you! Can I power 4 servos off of that battery pk rather than 2?

[chriskiepfer]

Thanks for the video! If I accidentally put 5V to the Gnd pin, will it cause any damage to my Arduino or the servo?

[eplusplus]

Very informative vieo! Thank you! What is that tool called which you drew your circuits on?

[afaqahmad]

Can I connect 6 Servos (3 big 3 small ) using these instructions ?
Using 12V external source for servos and 5V source for Arduino

Hi sir, may I ask if it possible for me to use MB102 power module to power my two sg90 servo motors connected to esp32? And a ultrasonic sensor is connected to 3.3v pin of the microcontroller. the esp is powered by the its micro usb.

[SebVEVO]

When you are using a separate battery to power the servos, wouldn't 5V USB now be enough for the Arduino?

[yatharth]

What if i had to connect 3 MG996R servos in this same circuit youve shown??? Would that work too. As i already ruined 2 previous servos by directly connecting them to the arduino only.

[thealmightybro]

i am working on a project that involves wirelessly controlling 6 mg995 individually using arduino nano on both transmitter and reciever side...so can i follow ur way or is there any more u can suggest..

[derpatel]

Excuse me, Mr, I am using an Arduino Uno R3 and it doesn't have the same power pins that your's has. How am I supposed to power a motor?
