Control More than one servo using ESP32 with library - Robojax

[@michah5761]

Thank you for video. You explained everything, except one: what power supply did you use?

[@robojax]

you are welcome. if your servo is 5V, connect to 5V power source and so on.

[@hansp.2911]

Thx for your alltime informative Videos ! One Beginner Question : Must I use only 5V for external Voltage or is it possible to use eg. 7.4V ? Thx for your Time

[@robojax]

you are welcome. The voltage for your servo is determined by the servo motor manufacture. if it is 5V then use 5V else connect different voltage. most servo motors are 5V.

[@Askaakash02]

Can you please make a video which you can control 16 servos with pca9685 with ESP8266

[@robojax]

I have it in my list. Coming soon.

[@mikedavis4039]

your videos are well presented and informative, i've been trying to work on some of my projects using servo's. I have little experience with using the arduino ide and have considered doing your tutorials. there is one area which which i can't seem to find much subject matter on. controlling servo's using two esp32's or HC-12 remotely.over distance. will you be doing any future video's on this topic.

[@robojax]

Hi, I have videos on controlling servo over WiFi. Check my videos. Once you can do it over wifi, then you can do it from anywhere the method used "windows remote desktop".

[@mikedavis4039]

@@robojax Thx, i have watched most of your videos on this topic, as i'm new to this topic i don't really understand how to apply the code for broadcasting between modules. i will keep learning and give myself 6 months to try and achieve a result.

Control pca9685 PWM driver over wifi app with ESP8266 and node MCU... Thanks again ☺

[@robojax]

I don't see any need for it. But I will try to make video on that.

[@majordeltadelta]

Great video and you are one of my suppliers

[@robojax]

Thanks.

your link on Servo Library for ESP32 (zip)--- Not available

[@robojax]

wow. thank you for letting me know. the first letter of "robojax" was changed to capital like "Roboja" and our server is Linux and it ignores it. Just changed the R to r and it works now.

[@jommelaxiegaming456]

Please make a video of 4 servo motor controlled by 4 potentiometers

[@robojax]

It seems you didn’t search. I have shown how to control more than 1 servo motor. More than 1 means any other number you want.

[@manarabd-elrahman489]

can I use the same everything in the video but change the servo motor to MG995!

[@robojax]

Of course. Servo is servo.

[@zyadd5089]

Thank you another time!!!

[@robojax]

You are welcome.

[@SHALINIMSWAROOP]

hello! can i use the same code(with minor modifications) and libraries to control multiple continuous rotation servos?

[@robojax]

Hello, "continuous servo" that is old on eBay is just joke. Don't waste your time. use stepper motor or get $300 servo that comes with software and will work exact like that.

[@SHALINIMSWAROOP]

@@robojax thank you so much for your reply! my project is actually to build a vending machine.. will stepper motor be the right pick to rotate the dispensing coils? also, does the circuit configuration remain same?

[@robojax]

I have tones of videos on stepper here is how you can find a video in a channel kzbin.info/www/bejne/hZnOhpabd7yWftU

[@SHALINIMSWAROOP]

Will look into that, thank you!

[@MrBMWerner]

Could you make a video with 4 servos and 4 potis to control with esp32? :)

[@robojax]

Hello, you could search, but here kzbin.info/www/bejne/labdaIyZhN-poLc You can learn from this (new) video and use it the way it is shown here with ESP32. So learn from both videos and combine them. good luck.

Salaam alaikum, if you are the guy who said "you are not from Canada", then I did not want to argue. الناس في كندا يندمجون من مناطق مختلفة من العالم. لقد وصل بعض الأشخاص منذ 20 عامًا ، ونحو 50 عامًا ، وحوالي 100 عام منذ حوالي 300 عام. أين ترسم الخط لتقوله من هذا التاريخ ، نسمي بروبل الأصلي. هذه ارض الله. إذا كنت طاعة لله وخير إنسان لغيرك وبيئة تجعلك خير إنسان بإرضاء الخالق. كلنا نأتي ونذهب. هذا مترجم باستخدام جوجل. آمل ألا يجعلها مضحكة. انا من خراسان الكبير. الآن في كندا.
