How to Arduino #3 - Servos

My Amazon recommended products:

How to use servos - I show how to connect and program servos on the Arduino. I am using the TowerPro MG995 and HiTec HS-322HD servos.

Dear Lonnie Honeycutt.

Even tho this video is quite old already, 4 years almost, i wanted to thank you for your time doing this. You took more than 20 minutes of your time as an adult, usualy busy beings, to make this content and share it with the world, editing and rendering the video and more stuff that we do not appreciate; and it is good, it teaches in a way to be understood . I think many of us should be saying this, Thank you.

This was actually the best Arduino tutorial I've watched yet. Great job Lonnie.

Thank you for doing the servo video. The audio and video were great and mostly even. This was helpful and worth watching.

People who share make the world a better place!

nice demo thanks for showing how some servos just jitter, i also seen servo that could only do like 100 deg of movment or something so maybe if you tried 20/160

the twitchy or what we in the RC field, call glitch, is most likely from a dirty pot or if the battery is low, you may see the output wheel bounce when it hits the end points.  and if you want to use them as wheels make sure you get one that has ball bearings, a standard servo was not meant to have that much side load.    mike

thank you very much, I have been looking at Arduino to add animation to my model railroad and you made this very understandable

Good video Lonnie..thanks. Just getting started. Doing mechanical Pinball machine Mods and needed this

Lonnie you're the real MVP! Great video!

Greetings, Lonnie. First of all, I think your tutorials are clear, concise and easily understood. I have looked a great number of hours online for a solution to my difficulty. I'm trying to program my arduino to control a continuous servo and a standard servo together in one arduino uno. I can make them work individually one at a time and no problems or conflicts. But when I put them together in one sketch I run into errors. I may have a syntax problem. I'm hoping you you could shed some light. I'm trying to control a camera slider with a Spring RC 4315R 360 servo and clicking the button on a wired intervalometer (plugged straight to the camera) with a standard micro servo. I'm very new to arduino and servos that I fear i might do damage (over-voltage) to my camera and the intervalometer, for that matter, if I make the arduino click the camera electronically from its output pins. That's why I think a mechanical click will be safer. I'm aware there's a variety of ways to skin this cat. I copied these codes from other generous posters online and have tweaked the numbers to fit my purpose and they work good individually.

Thanks for this tut, simple and well paced.

That lens coffee mug messed with my head.... can't focus on arduino project now.... :P

[staaaajn]

great video! i have a project with servos in mind. I think I know everything I need to know after this video! Thanks a lot.

I just bought a 1501mg analogue HD and am now finding Arduino won't power it for more than a few seconds, even though it says it runs at 4.8 volts, but I'm guessing the MA draw is too much. Now I'm stuck trying to find a 6V adapter which allows around 2500mA (stall torque). They don't seem to make them over 1A!

great video! amazing! you made the programming so easy!

[oliverpasquesi]

What servo would you recommend for a medium sized robot arm lifting typical items such as a medium sized screwdriver?
Thanks.

[AKSnowLeopard]

I got my servo working after rewriting the commands when you rewrote the sketch, but i'm not sure why it didn't work with the first sketch at the beginning of the video. And thank you for this video, it made much more sense than the book I was using.

thanks for the video sir, i'm planning to build a different kind of robotic arm for my first real project using arduino, and this video help me on understanding type and use of servo :D

Hello, all good about Arduinos and servos and other components. good stuff.

Hi Lonnie, great video, very useful for me as i am trying to build a four gate level crossing for my railway layout. I have four Hobbyking HK15178 servos and a mains (240volt) as i am in the UK to six volt DC power supply rated at one amp. can you tell me how i can operate the crossing gates from a switch controlled by my Arduino Mega 2560?
Cheers Phil
