Hi guys. I have to make a project for Physics in which I am creating a ride. I need to use 4 servo motors running at the same time. Can I power it from my Arduino directly as some videos say that I can or can I power it using a 9V batteries which some videos say its okay to do while others don't. If neither of this options are viable, I heard that a 5V power brick can be used. How do I plug that in (if it has chances of working successfully) and how do I wire up my servo motors? If someone could help out by posting a schematic that would be great!
No you can't.
What is this?
Not if it is a PP3 battery intended for low current applications such as smoke detectors
Hi guys. Its a custom ride based off an amusement park that we have to create for our assessment. Also, sorry but what is a PP3 battery and is a lithium 9V battery enough to do the trick?
PP3 battery, used for smoke alarms and the like.
For four small servos (SG-90) use a separate power supply providing 4.8 to 6 V at more than 3 Amperes. For larger servos like MG996R, the power supply must be able to provide 2.5 Amperes per servo, or around 10 Amperes for four. Don't forget to connect the grounds.
Hi, do you have any suggestions on what the power supply could be?
List all your devices. Note the maximum power required by all devices you will use. You can find this information on the side of the device, packing material, manufacturer's datasheet, and the internet in general. Get a power supply 125% (because you never want to use power at 100% capacity) the size of that power total.
That depends on the motors, the load, and how long you want it to run.
It's a matter of physics.
When you think ride, maybe think of e-bike battery pack or bigger. If the ride is stationary, can it run off grid power?
See post #5 for the required voltage and current ratings.
It's not very big. It is small, like 30cm in height and I am using 4 servo motors with an Arduino uno.
This should have been described as
"A model of a fairground ride"
It would have also been better if you stated what you ride it was going to be, or could it be any ride and you haven't decided?
As you have been told you need an external power supply to run any servo motor, small batteries will not cut it. You can run a servo off 5V, but for best results use a 6V power supply for the motors.
How fast will your ride go on servo motors?
Or will it be a steep climb and a free ride?
