Quick Guide to Servos

Read the full blog post here: www.sparkfun.com/news/3262
Hobby servos are a wonderfully simple way to add precision motion to any project. From the tiny micro servos used to pilot R/C aircrafts to the jumbo class servos when you really need some torque, if you learn to control one, you can control them all. Here we take a look at the three main servo sizes, and a couple of quick and simple builds to demonstrate what servos can do.

Would love to see more of this content. Great work.

[@fredicvsmaximvs]

Aahhhhh, that's the stuff! 😃

[@shadowreaperjb]

would love to see a follow up for "smart servos"

[@manotto3939]

Smart move 👍🏽

[@buder5116]

i would like to know where to get good servo bought some at local store and they dont even do 180 :S without going out of control

[@thavymeas6125]

very good

[@trialupload]

Nice

How do you find the Newton Meters of a servo? ie. A 13 gram micro servo

[@envisionMagic]

I wonder if someone can help me,
I need a basic servo that can move at least a quarter inch or a little less, it really doesn’t matter the exact measurement, the moment I push on my remote control. I already know how to connect a remote control but I just need to know if I’m doing this correctly, what I do is I connect one of the three wires to one side of a 9 V battery in the moment the other wires touched the other side of the naval battery, the server gets a little surge of electricity and it moves exactly the way I like it to move but I wonder if I’m doing this correctly, if I may damage the unit and if there is a better way, thank you in advance.

Pmw causes problems with sensors, look up emp. 200,000rf waves per sec. Plz run specs

[@bradyknowzbest1149]

Would .007 or .065 be faster rating

Haha- I heard "shouldn't be touching your face" which is something you pretty much never heard before the very beginning of the COVID pandemic and then heard "cold and flu season" and was like... wait a second, and then looked at the date. March 17 2020-which was that 2 week period when it was on so many people's minds but so many people were like "ssshhh don't talk about it- it's weird."

i have a problem
i want a servo motor to operate in 2 different speeds with 2 diffrent clicks on button
for example normal 120 degree rotation speed at single click and fast 120 degree rotation at double click using on off tactile switch using a cr123a battery.all these using a pcb or arduino in the most smallest space is it possible?

[@hakbrenden5024]

Create a variable for the switch so that its 15 when off and 5-10 when on, then replace the 15 mil delay of the servo you want to speed up with that variable.

I'm working on a project where I need to press a small lever to release a hidden 2" x 5" drawer, but the space is limited. A servo seemed like a great solution, but for my application, I'm trying to make it so if power is applied, actuate the servo (to press the lever). So far in researching and from what you're saying I need to have some sort of controller in place though. Do you know of any options where I can just have the servo arm move, say, 90 degrees when power is applied, and then go back to center when power is removed?

[@ADHD1080P]

you could do it with an arduino microcontroller, they are super easy to program and have a built in usb port, but if you want it to be smaller you could use an attiny85 or attiny10 microcontroller. If thats still too big you can lookup some tutorials on "555 timer servo driver" circuits and that can also do what you are asking, but may require some electrical trickery to get it to go to 90 degrees specifically. As for returning to the zero point, when power is removed a servo essentially goes limp, if that works for you then congratulations! Its going to be easy, otherwise, the device may have to stay on to hold your lever at the correct position

@@ADHD1080P hi ADHD, have you become a flat earther yet?

[@Wings_of_foam]

Why are you asking him that?@@flat-earther

[@flat-earther]

@@Wings_of_foam thorsoele well we were all lied to when we were taught that the earth is a ball flying in a vacuum

[@Wings_of_foam]

The internet is good for some people but is very dangerous for others.
I'm not trying to ridicule you, but I think you should take a break from it.
So, let's say the earth is not round. What would you get out of that knowledge? Would it change your life in a positive way? We have more serious issues to focus on.@@flat-earther

[@colemiller8832]

Train. Do you know what kind of train this is?

[@bestamerica]

'
i use very good HiTec / Traxxas servos are good on my any R/C tamiyas / traxxases...
few futabas servos

[@zee-lab-electronics]

What happens when servo did not find a pulse after 20ms?

[@zee-lab-electronics]

@Imperviousyes, that is the thing.

[@zulqadarabbas7567]

Any guidance on not to make the robot?

Already did a wireless mounting setup for a camera. th-cam.com/video/Vw29rO_lw6k/w-d-xo.html.

aahhh daff di stuff

[@segwaydave]

Mmmmmmmmm...... servoooooooooooosssssssssssss

Very interesting, but the background music is superfluous and annoying.
