Rotary Encoder Incremental rotary Encoder How to use it with Arduino

[@tomc8157]

I just hooked up a 10-30v fairly large encoder, fed the encoder 12v @ 70ma or so and worked like a champ. Shaft is a lot hard than yours to turn but works perfect first try. Counts 1-65k and back down no problem. Thanks for simple and clear video.

[@visionwarecomputervisionre9943]

In some case, it wont work with board's 5v .. if you want to use the board power ONLY, then you can open it up and short the outer pins of LM7805 (78m05).. Remeber its only if you dont want to use any other external power source.

[@firekizzz]

I have a homemade steering wheel project for games, just like Logitec, but I don't have the sketch to use the encoder, and I also can't load the sketches into the Arduino. what to do?

[@andrescarlini2071]

Hi Everyone! I´ve tried this code in arduino mega and works just fine. ( I have the same encoder only 360ppr) but when I try ir in arduino leonardo the counter stays around the same number. It starts working when I modify one of the interrupts to FALLING or if i just unplug uno of the pins. But only increments the Value. Does anyone knows what could be the issue. Thanks.

[@jorge-garcia-mateos]

I think the encoder you are using (see 0:14) has 600 pulses per revolution, not 400. Yours is type ...-600BM-... Thanks for the video and the code!

[@Bartosh.S]

Also this code is incrementing counter on both phases, so it 1200 pulses per rotation

[@jarisipilainen3875]

is it matter.all is it doing count pulses not revolutions xD

[@racingaddict3719]

Hi does it work? With arduino leonardo, i´ve uploaded the code and connected the wired scheme and in the monitor shows 1 2 and when i turn the encoder it doesnt go to 50

[@RightlyFree]

Thank you for sharing this video with us. There is one point to enhance the code: add max and minimum counter limits then flip the counter when reaching the limit such as:
void countClamp () { // clamp count from QMIN to QMAX:
if (counter > QMAX) {
counter = QMIN;
}
else if (counter < QMIN) {
counter = QMAX;
}
This function should be verified whenever updating the counter
I think in your case limits would be
long temp,counter = 0; //sign should be considered
#define QMAX 1199
#define QMIN 0

[@benrichards1410]

Hi A R, looking for some help, would this make the code deal with minus numbers as it currently goes to 65000 something when it passes zero? Any elp would be appreciated, been stuck on this too long. Thanks

[@luishnk3983]

how to solve limit counter ? how

[@bears7777777]

Make sure that if you're using velocity as a control input that you also account for the rollover. E.g. if the QMAX was 1000 and it goes from 980 to 20 in one dt timestep, you have to do some math. 1000-(prevCount=980) + (newCount=20) to get the 40 counts that the encoder rotated. Do this in reverse if you hit QMIN. If you don't do this, the counts/dt would be 20-980 which would give a speed of -960counts/dt which will throw off any control loop you may have

[@chbonnici]

I have an AC motor which turns 10 RPM . The motor turns a shaft with a chain . I want to measure and stop the motor when to chain travels 4 meters. Is this possible with this encoder.

[@davideronchin6400]

Anyone knows the max speed readable? I don't think the arduino can read all values if the encoder reaches 5000 rpm

[@edgarbernal801]

Is the reading you are showing in RPM?

[@tardraker4631]

yo tengo exactamente ese mismo encoder pero mi problema es que solo aumenta, no disminuye, creo que vino con defectos

[@angelabreu2676]

Hola, espero que no haya llegado tarde pero el encoder funciona, lo que pasa es que el codigo tiene deteccion de interrupciones en HIGH cuando deberia ser CHANGE modifica eso y funcionara

[@tardraker4631]

@@angelabreu2676 ya voy para 3 años con mi volante g29 ya que nunca pude resolverlo 😞 pero igual gracias

[@fernando.liozzi.41878]

I have exactly the same encoder, it came to me today from Aliexpress and if I don't put pullups on it, it doesn't work for me, I put the outputs on the oscilloscope and I see the signals very very attenuated, with pullups it works very well. What can it be due to, will I have failed? Regards.

[@fernando.liozzi.41878]

That's it, I'm not using it with Arduino, and I can't activate the internal pullups of the microcontroller, because I have opto-isolated input. The output of this encoder in NPN open collector, that's why I need to put external pull ups resistors. Regards.

[@prateekmusicoffcial]

can we calculate accurate angle using this??

[@ElectroCoderEC]

If the motor does 3.500 rpm, the encoder 1.000 pulses, does the arduino have enough capacity or are pulses lost? Thks

[@TechIsGods]

My homemade Six Digit, 20MHz, CD74HC192 Up-Down counter circuit counts Quadrature Encoder pulses at 20Mhz speeds. And seems to be many times faster than using my PIC16F887 microcontrollers.
Can you tell me why?

[@shobairbashiri9227]

you programmed it with rising edge on each pins A and B right?

[@ShahryarNaseem]

Can you please tell me how would you use this to calculate angle, like the line of code that should be added?

how can we measure length travelled using that encoder?

[@martijnvenselaar4760]

2*pi*radius gives you the length traveled in a whole revolution (radius = outer radius of pulley attached to the axis of the encoder for example).
Devide this length by the number of pulses per revolution, in this case 400. Now you now your displacement per pulse.

yes
0.01 deg means you need 360 * 100 pulses then you need 36000 puls.
that's mean you need 36000 / 400 = 90 encoder revelution per one turn of the motor shaft.

[@michelbitoli1388]

How can i contact with mail adress?

[@tasso6196]

Tks, it worked!

[@RovanRCTube]

my encoder reads 65535 per revolution at 115200 Baud

[@rolandkuka9987]

I has the same problem. Change variable type from int(int stores a 16-bit) to long (32-bit).
