How to control a servo motor from a Raspberry Pi without any jitter! Using Python you can control an SG90 servo motor from a Raspberry Pi with precision and no jitter. I use a Raspberry Pi 4 in this video, but it will work equally well with a Raspberry Pi 3 or a Raspberry Pi Zero.

Garry :) are the gpio pins interchable ?

@GaryExplains 3 года назад

Harmony OS is Android.

Excellent primer to servo programming in Raspberry Pi, plus a practical application! Bravo!!!

@codyflanagan304 Год назад

Hey Gary, Thanks so much for your concise tutorial. It helped me out so much with my camera tracking project

@ollocksbay 2 года назад

thank you dude!, i've been trying to program a robotic arm with a raspberry pi, when it wasnt slamming itself into the desk it was nearly backhanding me, this helped to explain why it kept shaking everywhere and so hard to control, thanks!

@jdeb0016 Год назад

Thanks for your kind explanation and your code :) Before I was only using a GPIO pin and my servo motor was jittering too much but with the PiGPIO it is working fine!

@muddyexport5639 3 года назад

Good vid! Look fwd to see the radar in operation.

@only1leddy 2 года назад

Helped me loads my servos so smooth now well happy mate

@thorsten9211 3 года назад

REALLY NICE! The most guides are a bit old and not so detailed. Looking forward to see more! (As always!)

@moeyali123 Год назад

I was worried when I first ran the new code, jitters were still there. I ran it a second time and it worked perfectly. Thank you

Loved it! I plan to apply this to ESP32 S1 in CircuitPython. Fingers crossed.

@HGmolotov 3 года назад

Really could have used this about a month ago for my Arduino, but hey, I got it sorted. Seeing how it's used on raspberry pi should be interesting!

@pisceesian1 2 дня назад

Very well explained. Can you please make a video on how to open/close a prosthetic arm using a servo. @Gary Explains

Hello Gary, Thank you for the nice intro, you're enticing me to use my Pi's GPIOs. Looks like fun! Well done moving the like/comment/subscribe/bell reminder to the middle. It may be problematic with the early leavers and the RU-vid auto-play feature or playlists. You may find convenient to use movie scripting principles, insert the reminder right at the middle point; the "point of no return" when you have your audience engaged and wanting more ;)

Hello Gary, The sweep script is very nice. I'm new to Python as was wondering if there is an easy way to sweep from 70 to 110 º and back to 70º for just 100 cycles. Any help would be greatly appreciated.

@mohitmw22 3 года назад

Hello Gary, I have been using the Raspberry Pi for a while now and we know how convenient it is to connect various sensors and modules using the GPIO pins. I recently found my Nordic Thingy 52 and realized I have the whole suite of sensors in one place that can be connected wirelessly to the Pi! I would like to know if there is an easy way for the two components to communicate?

@BrunoPereira-mo6kg 3 года назад

Hi Professor! Could you make a video showing the LTPO screens refresh rate changing? OEMs say the refresh rate could change between 1 and 120Hz, but I haven't found a video testing their claims... Could you do that please 😁?

@3D_dreams 2 года назад

Can u pls show how to reverse rotation of newer towerpro sg90

@andreinarita5156 Год назад

How you found the custom values for the min and max pulse width? How you know that these work for you?

@henkoegema6390 2 года назад

Can I use your method also on the Jetson Nano 2GB with a PCA9685 servo driver? 🤔 My servo's are jittering too much.

@TheUnofficialMaker 3 года назад

Sweet!

@MaxMax-wy7bi 2 года назад

Hi, I have to type after every reboot or normal Start: sudo pigpiod. Otherwise an error appears. How can I change that?

@rickhunt3183 3 года назад

I think you might find using a PCA9685 servo controller will make things much easier for you.

@ToxicBananaFish 10 месяцев назад

Form some reason, my servos won't stop at the min/mid/max positions, but instead just continue to rotate in whatever direction indefinitely

@Martin-fo9sj Год назад

Thank you, it saved me a lot of pain :D

@henkoegema6390 2 года назад

Thanks for this good explanation. :-) How can I add the terminal command "sudo gpiod" in the python script itself to start the deamon? And how to stop at at the end. Best regards.

@henkoegema6390 2 года назад

sudo gpiod = "sudo pigpiod"

how can i use two servos

@JasonMayes 2 года назад

Hi new to all this - can you let me know if i can connect 2 servos (exact ones you show here) to Raspberry pi 4b without any additional stuff? Or can it not power? My aim is to get a pan/tilt combo working with the raspberry pi camera 2 module. Totally new to this so any advice appreciated in the most minimal way possible - would rather not buy more stuff as it will go on a robot so want to keep weight to minimum.

@shadbud9198 2 года назад

Did you find out?

@JasonMayes 2 года назад

Hi ... I'm considering signing up for your newsletter, and was encouraged by your "no spam" statement. However, in the privacy policy linked from the sample newsletter it says "We use the information we learn from you to ...

Is there a way to sign up for the newsletter without getting spam from Android Authority? Thx.

@GaryExplains 3 года назад

Unfortunately the privacy policy needs to be broad to cover every eventually and the complex nature of privacy laws on a global scale. It also covers more than just my newsletter. As I say in the video. If you sign up all you will get is my newsletter. Nothing else.

oh nice. i guess this will make my autonomous weapon system a bit better. :-)

@bornach 3 года назад

The really cheap servos sold on Amazon and Ebay claiming to be Tower Pro are probably clones. Might explain why they don't adhere to the datasheet specs.

@rino19ny 3 года назад

maybe i missed it. where did you get the servo.min() function? please treat us as noobs.

@GaryExplains 3 года назад

It is part of gpiozero. The "servo" object is created first and then you can control it via that variable.

@moatezbenabdallah7589 3 месяца назад

What about Raspberry Pi 5 ?

@krestonkurotani3231 3 года назад

Probably too bulky to shove all of them onto a remote plane The radar though, ooooh

@armandolario6665 3 года назад

I don't understand why you call this motors SERVO-MOTORS: they are not SERVO, because they haven't any encoder for the feedback, then it's an open loop control, NOT a closed loop control. You will never be sure that the motor reaches the set position, you can do this only by means of a feedback that confirms the reached positions is the same as the set position

@MikePreston-darkflib 2 года назад

Inside there is a potentiometer which encodes the current position, so they are servo motors. There are tutorials about how to change these servos into continuous rotation by modifying the pots.
