Fantastic! Looking at pictures of waves just didn't do it for me. This video completely cleared it up. Thank you! Subscribed.

@cdweng840 6 лет назад

Brilliantly explained from theory to application. Well done!

@fanBladeOne 5 лет назад

Thanks once again for a greatly instructional video. After watching not only do you understand the principle behind it, you also have a piece of working code at the ready. Thanks alot :)

Great stuff! I was initially looking at some library to handle this but it’s so easy thanks to your explanation I’ll just handle it myself

@sub-arts128 3 года назад

well done. thats the best explanation for rotary encoder i ve seen so far

awesome seeing your videos again its been a long time since you uploaded a video !!

@voxellab4339 7 лет назад

Dejan, Great video! thank you. Got it to work. If I turn the dial to quick the nema jump, not smooth and has a pause when reveres. I've tried trimming the drive board and the delay times. Any idea?, thanks again for all you great work.

@cdersch636 7 лет назад

Do you know the maximum speed of the decoder? Can it turn up to 200 rounds per minute? I tested once and it was not counting correctly - so the question is - was a problem with Arduino or with the mechanic of the decoder? Thanks you

@jaimeriquelme6727 Год назад

Thanks Mechatronics for your time and work. From Sydney all the best. 👍

@jp040759 3 года назад

WOW. Finally I understand the rotary encoder logic. Best explanation I have run into in 10 years. Your description turned on the big light bulb on in my brain and I understand it now. The code is so simple too. THANX!!!!!

@afzalqureshi8091 6 лет назад

output is different from the code it gives only negative values on CW or CCW direction.

i would like to build a wireless follow focus for cine lens, what's your suggest?

@jeffbeck6501 6 лет назад

Thank you. Your code worked. I thought that Kevin Darrah's code using interrupts was working for me but it was not. It was skipping all around but your code works perfectly for me with no skipping at all. How u do dat? Thanks man.

@heshteach8212 7 лет назад

Simple and good explanation

@bekhzodkh 8 лет назад

Nice and clear explanation, thanks for the video. I wonder is it possible to control the LED light intensity using this encoder?

@hammadahmad1137 8 месяцев назад

Just use a potentiometer DUH

@sakshamsangwan6811 5 лет назад

What is the least angle it can move ? For example If I connect it to a shaft of a robotic arm will it give 30 counts with 30 degree change ?

@lukaszM46 6 лет назад

in this example was the encoder connected to 5v at the common pin and then pins A and B were connected to digital pins with pulldown resistors?

@denadaisicari 5 лет назад

@LifeGeneralist 3 года назад

Can you do a video on measuring the angle of rotation of the stepper if connected the encoder to the shaft of the stepper and if the shaft is rotated manually?

@kamranalidoosti9799 6 лет назад

Thank you Dejan. You are a good teacher. Go on!

@manishsingh2961 6 лет назад

can we use this rotary encoder? In bidirectional Bluetooth app led brightness controlar project

@muratcanbarut64 5 лет назад

would you please can you show the circle diagram for stepmotor section, is LCD connection I2C ? thank you

@m0gga 7 лет назад

Hi Dejan, thanks for sharing this helpful tutorial,I would like to use a rotary encoder to replace the menu navigation buttons in my project, your video is very useful. I notice that you did not appear to implement any software de-bouncing techniques to overcome the switch noise, yet your example did not appear to suffer from switch bounce. Did you use a hardware filter of some sort? Thanks.

@krallopian 6 лет назад

Yeah I was wondering about that. My encoder skips when I move it then when it clicks. So each "notch" counts as TWO. 0... 1,2... 3,4.... 5,6.... I suppose I can code accordingly but, slightly annoying.

@Xanty55 6 лет назад

Yes, my encoder produces the same behavior.

@itskevscott 2 года назад

Maybe the two Serial.print() statements in the loop slow it down sufficiently that the chatter has stopped by the time it looks around again. With a faster arduino like an ESP32 the bouncing may be seen again. Havent tested it but just a thought!

@pkteguh8199 8 лет назад

thanks for your tutorial, it helps,regards

@pkteguh8199 7 лет назад

referring your tutorial,so is it possible to synchronize two surface speed of conveying belt/goods ?, since the encoder rotated by a surface speed and give the signal as a control to a motor that can produce similar surface speed to another conveyor for example, thanks for your feedback,regards

@bcinsteadof3 6 лет назад

Wow, such elegant code...My overly complex code didn't work well when I spun the encoder quickly, this works flawlessly. Thanks!

@TheChrisey 3 года назад

It's not that elegant tbh, it should be implemented with hardware comparators and interrupts

@jimwithheld7217 2 месяца назад

@@TheChrisey Agree: the example in the vid is fine for slow speeds, and when there is feedback, such that if a count is missed, or extra, the user will self-correct, and everything is fine. For higher speeds, you need some hardware and maybe counters, which take care of the counts, and the main software just reads the counter any time it needs the values. Some of the Microchip PIC family have a hardware module built in. A quadrature Decoder. But you can also craft with some of the "soft" progamable gates, e.g. CLB and such. For very high speeds, e.g. motors at thousands of RPM, you can't really just poll the pins in a loop: you need hardware assist. Or very fast interupts might get you some of the way. But again: the example is fine for the right kinds of slower stuff. Also: switch-bounce shaping on the pins can be important, so you only get 1 count per count, not many. I did not look too deep at the code to see if maybe its state always handles that OK enough. A resistor and a cap might be enough, depending on the encoder used.

Hi if I want a very smooth Jog wheel for a Computer witch encoder would be great?? with RPP #?

how many turns does a rotary encoder have and how would i code it so that when i tuen the knob, it goes to the selected menu and i want to press in to select the menu

@asmaakter2929 4 года назад

If I use a magnetic encoder circuit in micrometal gear motor ...does it be work like stepper motor Wait for a quick reply

@yashgokhale5238 3 года назад

Thanks for uploading the video. For some modules above program functions only when INPUT_PULLUP is defined for CLK and DT pins

@Bianchi77 9 месяцев назад

@kanishka5prasad 7 лет назад

any idea of how to control a dc motor the this encoder feed back ?

@ghoomieletsgo2766 6 лет назад

can i use rotary encoder to measure the speed of a motor?

@Redtayal 5 лет назад

Me and my friend are making a wind turbine project that dedects and rotates to wind source. How can we use rotary encoder to sense the wind or can we use something else?

@chloemcholoe3280 5 лет назад

does it make sense to use this as an interrupt in your code or is that OP? cause if the project has other things to do i'm worried it'll miss this

@ahmedboudi1808 6 лет назад

@AbhishekKumar1902 7 лет назад

excellent

@OMNI_INFINITY 11 месяцев назад

*Thanks! Recommend making a video on controlling position of a continuous servo using a continuous rotary encoder!*

Currently working on such a video. I will publish it next week. Cheers

@OMNI_INFINITY 11 месяцев назад

Oh, thanks in advance!@@HowToMechatronics

@OMNI_INFINITY 11 месяцев назад

Another recommendation that is likely easy is a record and playback motion robot arm using servos. Bonus points for making it a pick and place machine with OCR!@@HowToMechatronics
