Very helpful. I learned some things here. Thank you. And thanks for staying focused in these videos.
I was so confused about powering an arduino, this has been really helpful, thanks a lot for this video ^^
thanks mate, i'm getting ready for a battle bot style tournament i'll have in april, this is so helpful
thanks, this was very helpful!
Thank you! The video was really helpfull.
Thanks for sharing your valuable knowledge
Appreciate your effort to educate
Trying to make 15ft of programmed LEDs for a cosplay. Very helpful video! My original tutorial didn’t talk about batteries. I really want a rechargeable battery tho instead of a regular so I definitely gotta do some looking!
thankyou very much! great start for us, just starting off from scratch because of a science project. it is really helpful to us students!
Excellent
This is absolutely amazing. I just watched all the lessons from the beginning, thank you so much for describing it all.
I'm a Software Developer, so the programming part doesn't cause me any trouble, but I was absolutely never a cable-lover-guy, so all those magic words like Servo-Motor or potentiometer are to me like programming language to people that don't know programming at all.
I'm glad you are still uploading new videos, can't wait to see more modules being implemented.
I'm interested in that wireless connectivity between two modules. Do you have that on your roadmap?
Unless the receiver from Lesson #18 (previous one) is the one I'm talking about and I'm being a dummy and will have to rewatch that one, haha!
P.S
Subscribed.
Thanks! We add these videos on an as-needed basis as we add new science projects to our main site, www.sciencebuddies.org. We currently don't have anything with two-way wireless communication on our immediate radar, but there are a lot of good Arduino tutorials out there for WiFi and Bluetooth devices. SparkFun and Adafruit electronics are great places to look for tutorials if you haven't discovered them yet. They are not part of the Arduino playlist, but if you have not seen them already you might also find our breadboard and multimeter tutorials useful: ruclips.net/video/6WReFkfrUIk/видео.html and ruclips.net/video/ts0EVc9vXcs/видео.html
This is so good. Thank you. I have a barrel jack adapter that has an output of 6v. It physically fits but I have the R3 Arduinoand was wondering if it will work at all since it's low.
It looks like the new R4 has an expanded input voltage range that goes down to 6V, but 6V is too low for the R3.
@@Science.Buddies okay, much appreciated. You are an excellent teacher!
Hey were did you get the switch which you can place on breadboard? Thanks.
If you search for "breadboard switch" on Amazon you will find plenty of options. This is a "single pole double throw" (SPDT) switch.
I am a rookie in the Servo motor world so please keep that in mind. Im building a very basic project that relies on a micro servo motor being controlled by a HJ Servo Tester / Consistency checker. Servo will be "continuous" type.
The micro servo will be attached to a small penlight laser pointer that has a USB connector for charging.
I really don't want to use an external battery pack with 4-AA batteries to power the tester.
Is their an adapter cable that would be USB-A at one end and a a standard female servo motor connector at the other end.?
For a power source on the USB will be a usb phone charger that is 5 volt/ 2 amp. Thank You
We're not sure about a direct USB to servo adapter, but there are a variety of adapters that will let you break out USB pins to access the 5V from a breadboard, such as www.sparkfun.com/products/9966
Great video but I can't find the video about powering motors seperately
This is the video you're looking for: ruclips.net/video/XrJ_zLWFGFw/видео.htmlsi=eQaXZpOPQfDz54ws
Very good video. You clearly said that the input voltage should be in the range of 7-12 V, but what about the current? In my case I got a 12V, 2.5 A wall adapter, but in the video the current is 0.5, so I'm not sure if it's safe to use this adapter to power my arduino uno rev 3, because of the current of 2.5 A. Please help me. Thanks in advanced.
Hi - the current rating is the *maximum* current that the adapter can provide, so that is fine. The Arduino will only draw what it needs. The important thing is to make sure that the voltage is in the 7-12V range because, for example, a 20V adapter is going to do its best to provide 20V no matter what, which is too much for the Arduino.
I want to wire a single mg995 to an arduino and I want it to be battery powered (preferably aa). How many batteries should I use and where should I plug in the input and output wire?
Hi - we can't provide help with individual projects like this, you will need to either consult the manufacturer's documentation or ask for help in the official Arduino forums.
I'm trying to make the artificial pancreas project on your website.. What would be the best way to power that?
It depends on what type of pump you purchased - the 5V pump should be able to run directly from the Arduino and not require separate external power.
@@Science.Buddies I got a 6V Pump.. Will that be able to be powered by the Arduino?
What if the battery holder doesn't have a plug for a jack cable?
like a battery holder with a regular red and black cable
You can buy an adapter like this: www.amazon.com/Power-Connector-Female-Adapter-Camera/dp/B07C61434H/
How much input voltage bettary generally use for arduino nano?
Hi - all our tutorials are for the Uno, you would need to look up the specs for the nano or ask on the Arduino forums.
hello, I'm powering 36 micro servos off of two servo controllers. I used a battery power supply but it didnt work. Any ideas?
can i put 12v battery on a barrel jack and connect it to the arduino?
Yes that should work!
how much battery volt we need to use power 2 x nema 17 stepper motor.... And what source of power supply need to use to power arduino?
Hi - we don't have our own stepper motor tutorial yet, you would need to look up the datasheet or tutorial for that specific motor.
i tried 9v jack but with a 9v battery and the voltage regulator keeps getting hot, what should i do? i need my project to be powered through a 9v battery. output is 9v 650 mA
You need to see two things. The power accepted and the power that is being pulled. If the power being pulled is bigger than the power accepted, it can be hot.
You could also try to ventilate.
How about 12volts battery in arduino uno? Would it work? And how long will it work?
You would need to look up the specs for the Arduino model you have (there are multiple different versions of the Uno now) on the Arduino website to be sure. How long the battery lasts depends on the capacity of the battery and what you are using it for.
@Science.Buddies I'll be using the batteries for the ptc heating element and peltier cooling element (both 12volts) which both can be controlled by (2 separate) arduino.
That device in your hand at 2:30 not a charger, it is a power supply.
Serious question. Does the 9v battery work with a nano
All our tutorials are for the UNO, you would need to look up the specs for the Nano on the Arduino website.
@@Science.Buddies thank you for tellling me. I will be ensure to look it up but thank you for making a tutorial
Can a 5v 2A adapter power my Arduino uno ?
Not via the barrel plug because 5V is not high enough, but see this page for alternatives: docs.arduino.cc/learn/electronics/power-pins/
Is the 9V battery enough to power 3 servos? I am making an animatronic eye project that should last a long time. It has on 3 servos, and I'll be taking it to cons, so I want it to be able to last at least 6 hours, without having to switch the battery every time. (Maybe a rechargeable battery?)
9V batteries generally aren't good for powering motors for an extended period of time.
Nope. I connected barrel jack to the Arduino. It doesn't work. I built a binary counter in a breadboard. I wired the breadboard to the Arduino. when I connect the Arduino to the computer via USB, the program works fine. When I connect the 9v battery to the Arduino, the LED on the Arduino itself is on. So, that tells me that the battery works. But when I try to run my binary counter program by using only the battery, it does nothing. Unless the Arduino is connected to the computer, the binary counter doesn't work.
It’s because your barrel jack isn’t center positive
U
I cant stand when the video says "we will link this info in the description" and the description is the generic support us stuff. WHERES THE VIDEO ABOUT POWERING OTHER MOTERS??
I bite my thumb at you which is a disgrace to you, if you bear it. Eeeeeeeaarh!
