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.

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!

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).
Regards

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.

Thank you for your kind reply.
You've mentioned that pins 2&4 are output, then mentioned that pin 2 directly is connected to plus, also pin 5, you said that it is grounded, then said that it is connected to plus via resistor R1.
Thank you for your time.

M;e: Yes, you are right. The sensor Pin of B is running to pin 1 (not to pin 2). Furthermore lus runs through a series resistor to pin 6 (not to pin 5). Thanks for your feedback!

Hi
Could you review the explanation of Figure 7 because I think there is a mistake when you talked about the numbers.
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.

M. Radwan

Me: I can't find something wrong with the explanation of figure 7. What do you think is wrong? It is from a Canon printer.
I have collected some old printers that I will disassemble in the next weeks to make a video about theire photo sensors. I will explain in more detail how to figure out the pin configuration of unknown devices. Be patient...

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?

Can you tell me how to send signal to the motor by using Arduino IDE serial portvto check its working.

Me: Forget about Windows, install Linux (I am using Ubuntu 14.04LTS) and use the command line tool I have written to control the motors. Otherwise you must write your own software or at least adapt the Arduino sketch.

Excellent presentations. Taking the measurements, doing the math, stressing the limits, analysing the results, and explaining how and why they differ from the expected or ideal. These are the things that make it a real education.

For the sake of clarity, the more common term for inaccuracies due to drive train looseness is 'backlash' which affects the 'theoretical' precision.

Many thanks.

Hello again Norbert,
 I have a few questions, 1. Can a hall effect sensor be used in a similar manor as what you've done with the optical encoder here?..2. (circuit design question) Could a person somehow use the weak brushless motor from a CD ROM drive as a rotory encoder? The ones I have seen are mounted with 3 tiny hall effect sensors. Between the sensors, coils, and magnets, could there be a way to attach it to one of transmission gears and determine rotational position? Thanks! -Jake

Me: Yes, you can use hall effect sensors, thus you can use the brushless motor from an optical drive to detect rotational movement (they indeed have those sensors on their board). I will demonstrate that sometime, but it's more than a few words in a comment.

Hello ^^,
I've been checking the code of wiper servo that you've shared for us, and I have some queries:
* Firstly what is the value of setPoint that should I test.
* I found this part of code:
 (double)(millisNow - millisStart) _ 1.0
I think we cant use arithmetic signs with unsigned long variables.
* In the last part of the code says
if(Serial.available_0){
readByte = Serial.read()
if(readByte == 20){...}
How can I introduce the ASCII from 20 to 13 if they aren't able to typein SerialMonitor

Me:
* setPoint is the point the wiper servo should try to reach
* we can if we consider a loose of precision
* It's transmitted through the program "commands-CNC" from the download package. Change that to ASII values if you'd like to type commands directly through a serial monitor (but I haven't tried that).

Hello,
Do you think it is possible to convert the signal of software (step / Dir) as GRBL, in points for the encoder using Arduino? You may use common libraries for stepper motors with DC motors or are there better solutions?
Thanks
Sorry for bad english.

Me: Of course this is just a software issue, but you can't use the existing Arduino stepper libraries to do so. You will have to write your own code or libraries. Since the control loop of encoder disc and DC motor needs much computing power you won't be able to run the GRBL software on the same Arduino, thus you will need a second one.
Your English isn't worser than mine.

Vielleicht nennt man in DE das nicht ein Simulator, sondern was anderes, aber ich meinte eine Software wo man ein Plan von sein Projekt machen kann.
Aber egal. ich habe schon paar Sachen gefunden
lg
m.

Me: Abbildung 1 ist aber keine Simulationssoftware, sondern lediglich ein in Libre Office Draw gezeichneter Schaltkreis einer Gabellichtschranke.

Hallo !

Ich möchte mich vom ganzen Herzen bedanken für die Arbeit Sie leisten.
Ich bin Einsteiger. Momentan bereite ich mich für die IHK  Prüfungen für IT Systemadministrator.
Komme vom ganz andere Ecke - habe nur humanitäre Wissenschaften gelernt.
Daher ist jetzt alles sehr neu und INTERESSANT!
Meine Frage: können Sie mir ,bitte, eine Software für El.Schaltkreise Simulation vorschlagen?
Ich arbeite meistens mit Linux Mint, Ubuntu 14 LTE, habe auch Lappi mit Win7. danke!

Me: Danke für die Komplimente!
Eine Simulationssoftware kann ich die leider nicht vorschlegen. Ich simuliere nicht, ich bastel drauf los...

One more question -- why does black paper block IR so well though plain doesn't ?

Me: Black paper is black because it absorbs light - at least the frequencies of visible light. IR is nothing but light with a low frequency. Plain paper is usually white, thus it doesn't absorb (visible) light.

Sorry about that, I keep forgeting how many days have passed.
So, how to make The circuit part has a black thing which can be used to detect if something is between the two sides.
That thing in figure 2 on this page.
Any special material required?etc etc
Thanks!

Me: I did not make those parts - I purchased them. Search for "transmissive photosensor" and you'll find plenty of them for a low price.

Sorry about that, had to cut short on chars. Regarding re-purposing printer encoder, I first tried 3.3v that gave nothing so used 5v. I used an aluminum foil (used for wrapping food, US) doubled-up as blocking strip. I do not see an option to upload pic. sending email with pics. Appreciate your help. Regards, MK

Me: That aluminum foil should block all IR light. What about sending an E-Mail? My comment system has indeed no option to upload files. It's just meant for dropping short messages.

Hello Norbert,
I will first thank you for all the great work you have been sharing with us. I have a similar motor encoder from a printer that I wired as you have shown. I can see the common ground and power to led and trasistor. The remaining wires I hooked to my multimeter but only get 0.78v blocked/not bl. Does the Trans not need input power at the collector and a kind of volt div to read output. I tried it but still same. Please let me know the correct circuit. Regards, MK

Me: What about some photos of your encoder with your wiring? What voltage do you use? How do you block the sensors (use a metal blade)? I'm no mentalist...
