  Can you say me in this which wire is +,gnd,rx,tx and what is the input of voltage and what ppr it has

Me: What about asking the seller for the datasheet?
I guess red has to be connected to the anode (usually +5V), black is ground and yellow and blue are the sensor outputs.

Can you make a rotary encoder with hall effect sensors?

Can I use Vishney TCUT_1600X01 as alternative in this project?
Thanks
Mike

Me: What project are you talking about? I am no mentalist...
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.

Könntest du auf YouTube bitte mal ein Video über die Software für die CNC und Lichtschranken machen. Also die für den Arduino und wie das mit dem GCODE ist.

Danke.
Gruß David

Me: ...über Software macht man keine Videos. Wie Programme funktionieren lernt man nämlich nicht durch "angugge" von Quellcode, sondern durch Lesen und Verstehen. Den Quellcode zu meinen Programmen gibt's aus diesem Grund als Download.
Geschriebene Kapitel zu Software und zum Basteln eigener Geräte gibt's demnächst mehr unter dem Schlagwort "Physical Computing". Ist nicht an einem Nachmittag geschrieben und um Programmieren zu lernen bedarf es mahr als nur mal eben eines 15-Minuten-Videos. Das dauert Wochen, Monate, Jahre, um richtig gut zu werden. Hab Geduld.

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.

You can control? Thank you

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.

Dazu wünschte ich mir Einführungen in die Programmierung unter Verwendung Deiner Videos als DAS Sahnehäubchen! Machst Du so etwas auch?

it's 2750 RPM at 30v rated, but I'm using it with 12v, even rotating with hand skip pulses...

Me: Well, that's approximately 200 rounds per second, thus 40000 pulses per second. With a 16MHz microcontroller, you get 400 clock cycles per loop, that's not very much. You need an efficient code block, or have to reduce motor speed or use a sensor with clearly less PPM.

Hi, thanks for your last answere, I'm trying to control a DC motor with a 200 PPM encoder but no one of sketches in downloads working fine, the stepper sketch skip pulses only works with ultra low speed, and the printer motor sketch has no so much functions as stepper. Could you explain what modified each variable on the sketch or how to modify it to work with 200 ppm encoder please.

Regards

Me: What's the revolution speed of your encoder wheel? Looks like there are too many pulses coming in per second. The printer motor sketch is working as stepper motor using interrupts.

Some suggestion? or I have to use under linux? because I tried it but I got the same issue (on livecd mode).

Me: The new Arduino IDE opens all files in the directory. Ensure to only load the *.ino file in your IDE. I have changed that in the new download package.
The commands-host.c won't compile under Windows. It's a Linux command line tool. Get e.g. Ubuntu 16.04LTS on your disk - it's the better (free) choice for free programmers ;)

Hallo,

wie hast Du die Encoderscheibe auf die Motorachse des Scheibenwischermotors bekommen?
Auf dem Bild/im Video sieht mir das sehr nach einem Motor wie er im VW Golv verbaut ist aus.
Damit spiele ich auch. Die Motorwelle ich aber erstmal nicht zugänglich, oder?
Hast Du da was aufgebohrt? Hast Du evtl. ein Detailfoto?

Me: Ich habe ein Stück der hinteren Endkappe des Motorgehäuses abgesägt - quasi der "Deckel" des hinteren Lagers. Damit ragt die Motorwelle einen Millimeter aus dem Gehäuse und daran habe ich die Scheibe fesstgeklebt. Der Motor ist von einem Mercedes, aber alle Scheibenwischermotoren die ich bislang in Händen gehalten habe sind an der Stelle ähnlich aufgebaut.

I have an encoder from hp printer, it is built in the main board of the printer not like yours, I could not trace the connections because the board is double face,  the ( agilent encoder 18 9970 5508)are written on it, I could not find the datasheet in the net, could you help me to fix the right wiring connections.
Thank you for your time.

Comment:
In one of the other YouTube videos that you showed this encoder and servo motor being driven as a stepper motor, I left a comment about seeing how to integrate a Heidenhain glass scale encoder into an OpenBuilds C-Beam CNC machine that we have recently bought for a $1000 and the scales that for 3 axis can be bought for an additional $300.
how one attaches the output of the encoder to the Arduino Mega so that all 3 axis stepper motors 3x4=12wires encoders 3x12=36 total 48 (some can be combined)

Me: I never had an OpenBuilds C-Beam CNC nor a heidenhain glass scale encoder in my hand, not even an Arduino Mega...
I guess the encoder is an absolute encoder? What software are you running on the Arduino (or do you try to run on that device)? Stepper motors can be controlled by just two pins (Step/Direction). Maybe you could use one microcontroller for each axis if there aren't enough pins on just one of them, or use some kind of serial registers or multiplexer?

Wenn ich Sketch und Schaltplan richtig verstehe, sind Pin 8 und 9 zu Dauer +5V Pins umprogrammiert worden. Richtig? Funktioniert das auch wenn ich R_EN und L_EN von der H-Brücke zusammen an den +5V Pin anschließe, oder reicht die Spannung nicht bzw. wird der Pin überlastet?

Vielen Dank

Me: Du hast den Sketch richtig gelesen und ja, diese beiden Steuerpins kann man auch einfach mit dem +5V Pin verbinden.

Hallo, funktioniert deine CNC Maschine auch mit einem Raspberry Pi und wenn ja, könntest du da mal ein Video zu machen?

Danke

Me: Version 2.1 könnte man mit einem Raspberry Pi betreiben. Dazu müsstest du die Software allerdings anpassen. Da du nicht der Erste bist, der danach fragt, werde ich das eventuell bei Gelegenheit in Angriff nehmen.
Warum fragt ihr immer nach Videos? Habt ihr das Lesen völlig verlernt? Schreiben scheint ja zumindest noch zu funktionieren ;-)
