Can you please give a reference for the information about the needed voltage in figure 2?

Me: The maximum voltage of this kind of sensors depends on the maximum collector-emitter-voltage of the phototransistor on the sensor side, which is listed in the datasheet. Common types can easily withstand 12V and more. With the maximum forward current of the LED (diode) as well as the maximum current of the phototransistor you can calculate the minimum values of the needed series resitors (a bit more is recommended).

Under folder printer_motor I seen code
in which there is option where serial port is waiting for user input in end it checks against user input
i am talking about this code section.

what to enter at Serial input - I am talking about ASCII input from 13 to 20

Input is waiting from user - otherwise it just write X on terminal ? What valid input is accepted
I refer to Figure 8 on this web page on  my left

Me: Than means your computer can't find the Arduino. Start yopur computer with the Arduino not pluged in. Open a Terminal and type:
ls /dev
Now plug in your Arduino and type:
ls /dev
again. There should be one more entry in the list. What's the name of it?

What are commands to send by Serial port ?
Did you mention any where - what are commands from 13-20 in read Byte
How to move motor ?

Hallo Norbert, die Schaltung sieht folgendermaßen aus:
Arduino Leonardo
16*2 LCD (8,9,10,11,12,13)
2 Gabellichtschranken an Pin 2 und 3
L298N enable Brücke gesteckt. IN1 an Pin 5 und IN2 an PIN 6, DC-Motor mit Sensorscheibe 15 Zähne.Die Software mit der Interrupt-Pulszählung funktioniert.
Die Software Stepper-Motor mit der commands-host geht nur so, dass der Motor in eine Richtung dreht und  bei wiederholter Richtungstaste auch auf Dauerbetrieb läuft. Die andere Taste bewirkt max. Stillstand. mf

Me: Was ist "die Software mit Interrupt Pulszählung"? Welche "Software Stepper Motor mit der commands-host"? Ich habe mehr als zwei Programme veröffentlicht. Eine genaue Angabe, auf welches Download-Paket (Name der heruntergeledenen Datei, welches Programm aus dem Paket) du dich beziehst ist nötig - meine Fähigkeiten als Gedankenleser sind seeeehr begrenzt. Richtungstaste habe ich bei meinen Beispielen nie verwendet (glaube ich zumindest). Ich habe immer noch keine Bilder von dem was du gebastelt hast...

Hallo Norbert,
ich habe den Aufbau nach Abb. 5 nebst der zugehörigen Software nachempfunden und leider funktioniert das nicht so recht. Da die H-Brücke mit nur zwei Signalen angesteuert wird (so meine Lesart) müssten diese Leitungen einen Festpegel haben um jeweils die gewünschte Drehrichtung zu erreichen. Nach der Software gibt es einen DIR und einen PWM Ausgang. Wie genau werden die dann auf die H-Brücke gelegt? Ich komme da nicht wirklich weiter. mfg Roland

Me: "Es funktioniert nicht so recht" ist keine Fehlerbeschreibung mit der ich dir weiter helfen kann (viiiiel zu ungenau).
Welcher der beiden Eingänge der H-Brücke als PWM Eingang gewählt wird ist egal, der zweite wird somit zum DIR Eingang. Abbildung 5 ist auch nur ein Foto, kein Schaltplan. Was genau hast du aufgebaut, welchen Microcontoller verwendest du usw. usf.
Bilder deiner Schaltung wären hilfreich. (siehe Rubrik Kontakt).

Comment:

an absolute encoder of 5 bits could be used in an arduino, to know the position in degrees of the movement of a lever and to control 2 relay outputs. the concept would be that turning the lever to the left activates an output of the relay and turning it to the right control the other relay output and know the position of the lever at each moment the movement would be in the range of 0 to 180 degrees.

Me: Is this comment meant as a question or did you just want to throw in your idea?

We had watch your video details on Youtube and it's help us almost 70% of our final project at diploma level.

Good day

I was just wondering how you attached the encoder to the back of the wiper motor. Aren't they normally closed and wouldn't opening it up have a effect on the operation of the motor itself.

Thank you in advance

Me: I cut off the back of the motor housing and glued the encoder wheel on the motor shaft. It still works fine. Most wiper motors have simple bush bearings.

Hello Sir,,

I am confused on your "Stepper Motor" program where I found DutyCycle , and I had learned about it, but I'm still confused about how to determine MaxDutyCycle and MinDutyCycle.. Can You Help me?

THX

Me: You must find those values experimentaly. MinDutyCycle is the duty cycle when your motor starts spinning. MaxDutyCycle limits the maximum power delivered to your motor. So if your setup shows to much overshooting or "bad vibrations" and you can't stop that by reducing the proportional factor, you should reduce MaxDutyCycle.

Comment:
I had a look at the source code "LCD_rotary_encoders_nterrupts" and the ISR (checkState()) is fairly complex.
I usually attach the interrupt (change) to only one sensor, leaving the second sensor as a normal input.

In the ISR is then:
If both sensors are on the same voltage level
Increase the counter
Else
Decrease the counter

I always use this concept with good results. I think it may increase the max freequency of detectable pulses. I'd be interested in your opinion.
Regards,
Seamiki

Me: You get more pulses per second, but only half the resolution possible. I will add a chapter about interrupts and rotary encoders in my series about "Physical computing".

Rotary encoder or: How to build a digital servo using an Arduino and photo sensors

hola como estas referente a lo que haces en este video estoy trabajando en algo muy similar ya vi tus codigo en descarga pero no estan completo soy un poco novato estoy aprendiendo te esplico lo que necesito

1 inicio con un pulso en la entrada x
2 ejecuta salida en x
3 cuenta pulsos hasta cantidad programada
4 tiempo de espera.
5 ejecuta salida en x1
6 cuenta pulsos hasta regresa a punto 0 de inicio
7 fin

adicional mente agregar potencio-metro para aumentar y disminuir cantidad de vueltas (programar)
pantalla de 16x2 lcd. para reflejar información de vueltas programadas 1/10 (0,0)
y números de ciclos ejecutado (este se debe de reiniciar con pulsador)

estoy tratando de utilizar tu código pero no doy para combinar todo podrías ayudarme?


Me: First of all post in German or English to save my time. Using Google translate costs me a couple of minutes to do that job.
Secondly, I am not the guy that does your coding work for free ;-)

Hi Norbert,

I am struggling with the code to use a DC motor with encoder from a printer. Is it possible to have a look at your code?
I am using a Raspberry Pi, programming with C++ and using the bcm2835.h library

Thanks,
Daniel

Me: My codes are available in the column Download.
However, you won't succeed in using a Raspberry Pi with a printer encoder, because those encoders have a high resolution and so change state quickly when moving the print head (or the paper feed).
The Raspberry Pi has no realtime operating system and so will inevitably loose input pulses. I am using an Arduino with hardware interrupts to read the printer sensor in this chapter.

The sensor you refer to is a double sensor, thus you only need one TCUT_1600X01 to creare an encoder. Have a look at the datasheet to find the series resitors needed and it should work.

Hi there,

Thought I'd just say that this has been really helpful in creating my own rotary encoder for a project I am doing. I just wanted to add that in paragraph 2 under the heading Figure 1 you mention calculating the required current for the LED and state in your calculation you used 180 ohm but just before that said 180k ohm. Think that's just a typo, but everything is very thorough and well explained. Thanks for doing all!

Me: Yes, 180Ω is the correct value for the resistor. I have fixed that, thanks for your feedback!

Hallo Norbert

Hab da mal ne Frage.
Bin was interrupts angeht ein nockabatzl (kenn mich nicht aus)
:)
Denkst du, könnte man auf die interrupts bei der feinen sensorscheibe verzichten, wenn man
anstelle des uno eine arduino due platine verwendet.
Sollte laut hersteller schneller sein.
Ist nur so ein gedankenspiel.

Schönen gruss aus österreich
und weiter so.

PS: Was hast du eigentlich für eine ausbildung?
Dein wissen und deine fähigkeiten sind ja phänomenal!

Me: Mit einem schnelleren Mikrocontroller kann man die Sensorscheibe natürlich schneller abtasten (Faktor 5 auf Grund der Taktgeschwindigeit). Aber auch der Arduino Due kann die Scheibe noch deutlich schneller abtasten, wenn Interrupts verwendet werden. Nicht auskennen ist keine Entschuldigung, wir alle wurden als nockabatzl geboren, haben aber die Fähigkeit zu lernen in die Wiege gelegt bekommen ;-)
Appropos Ausbildung:
Ich befinde mich nach wie vor in meinen Lehrjahren. Mit jedem neuen Projekt lerne ich was dazu und muss mich in die ein oder andere Thematik erst einlesen. Begonnen habe ich mit Elektrotechnik im letzten Jahrtausend während meiner Ausbildung zum Physiklaboranten.

Lieber Norbert,

wir haben Abbildung 1 "gesteckbrettet" und alles funktioniert grundsätzlich. Die Pinbelegung war der Platine zu entnehmen. Bei Eingang 5V, R1 = 1 KOhm und R2 = 10 KOhm messen wir 1.82 V offen und 4.96 V bei unterbrochener Lichtschranke. Der Ausgang am Sensor stimmt also soweit (bei Unterbrechung). Die 1.82 V offen sind aber zu hoch wenn wir alles richtig verstehen. Frage: R1 muss kleiner werden, damit die IR-LED heller wird und der Phototransistor schließt?

Lieben Gruß,
Thomas

Me: 1kΩ ist ein relativ hoher (sicherer) Wert. Ich würde also schrittweise kleinere Vorwiderstände auf der LED-Seite verwenden und sehen. ob die Spannung bei offenem Sensor runter geht. Üblicherweise werden auf den Platinen in den Druckern Widerstände um 100Ω verbaut - ihr habt also noch "Luft nach unten".

Hello Mr. Norbert. Many thanks to you for the work done. I very much hope that, if you do not mind, you can help me and give a hint. I want to repeat the figure №10. I downloaded the package "rotary encoder". The picture (wiper-servo-BTS7960)is specified as to connect the motor.
RPWM Pin 5
LPWM Pin 6
R_EN Pin 8
L_EN Pin 9.
In the sketch of "rotary encoder\wiper_servo" folder stated otherwise.
ENABLE_R 8
ENABLE_L 9
MOTOR_DIRECTION 5
MOTOR_PWM 6.
This sketch for another motor driver? Please help.

Me:
R_EN = ENABLE_R = 8
L_EN = ENABLE_L = 9
RPWM = MOTOR_DIRECTION = 5
LPWM = MOTOR_PWM = 6
The lables in the sketch differ, because I used an older sketch and just modified it for the new H bridge (BTS7960). It is the correct sketch and you can use it.

Hi! Very nice explanations!
I am a little bit confused regarding motor printer. In the pdf schematic (picture) the encoder is connected to pin 3&4 but in the sketch are defined to 2&3 pin.
Is something I missed?
PS - how could I send from Arduino serial console some commands? I am an beginner :(

Me: In the printer-motor.pdf as well as in the Arduino sketch (subfolder "printer_motor/Arduino") of the download package rotary-encoder.zip, the pins are 4 + 5 for motor control and 2 + 3 for the sensors. Nothing to be confused about...
I am using the Linux command line software to talk to the printer motor. If you'd like to send commands through the Arduino IDE Terminal window, you must change the lines:
if(readByte == 20){
to e.g.:
if(readByte == 'a'){
in the Arduino sketch so that sending an 'a' via Arduino terminal triggers the according command.

Hi, thank you for your brilliant work, I need from you the whole code of a homemade servo and the circuit for sweeping with arduino uno, i have a good geared dc motor with max voltage 12v and 2 Ampere current, thank you a lot a lot.

Me: Read the whole page before posting a comment. There is a link to the software I was using in the video:
Download package rotary encoder

Meanwhile, I thank you infinitely for the clarity of the movie and also for PDF patterns.
Thanks to your videos I started studying Arduino and I wanted to ask you to check the chart pdf wiper-servo BTS7960 'cause the pin on the H bridge BTS7960 (VCC, R_IS, R_EN, RPWM GND, L_IS, L_EN, LPWM) are not connected as in photography.
You can control? Thank you
Alessandro

Me: I have corrected that in the PDF and did a minor change in the Arduino software code (the bridge is now enabled and disabled by software).
Thanks for the feedback!

Hallo Norbert! Je länger ich diese hervorragenden Videos sehe und Deine kurzen, aber voll verständlichen Texte bearbeite, desto mehr hätte ich mir solche Dinge zu meiner Jugend- bzw. Studienzeit gewünscht! Jetzt, nach mehr als 30 Jahren -mehr oder weniger erfolgreicher- Elektronikbastelei, möchte ich auch noch in die Anwendung von Mikrokontrollern einsteigen. Dazu wünschte ich mir Einführungen in die Programmierung unter Verwendung Deiner Videos als DAS Sahnehäubchen! Machst Du so etwas auch?

Me: Eine Kapitelreihe zum Thema "Physical Computing" mit Arduino Und Raspberry Pi ist geplant. Es werden aber noch einige Wochen / Monate vergehen, bis ich damit anfange. Fände ich einen finanzkräftigen Sponsor, ginge es schneller...
