Finished 2DOF 12V DC wiper arduino playseat

[Greg1976]

Hello Racing Mat
As we talked. I´m sending you the information about the motor driver and motor.
Please check it how to connect the motor driver to the Arduino UNO board. As I told you I´m not using the motor monster because it has not power enough to support that two motors I´m using.
By the way the pot I´m using are 10K but they are very exactly. I mean I need to turn them about 10 times from start to end.
Here the data of the motors.
DC 12V / 160W / 50rmp
If you need such a motor driver for yourself so as I told you already in the past time I can help you with this. They also have bigger one for example 48V / 100A.
And here the links for the Motor driver and the motors.

Hello!

If you're using more powerfull motors, you can use one Motomonster per motor. Follow the specification of VNH


10 turn pot won't really fit: it will work but you will loose accuracy
unless you use gears to use the whole range

I cannot read the driver specification: does it requires 1 pin for PWM and 2 pins for Direction?
or 1 pin for PWM and only 1 pin for Direction?

Hello May. I try here to explain my issue.
As i already send you by e-mail i have a problem to connect my motor driver to the Arduino board. I do not use motor monster because i need mote power for my two 160W DC12V motors.
Here are the URL´s

It would be very nice if you could help me with the connection.
If you need more informations so just let me *

Regards

As I told you earlier, I cannot read the driver spécification in chinese.
You have to tell me if your driver requires 1 pin for PWM and 2 pins for Direction?
or 1 pin for PWM and only 1 pin for Direction?

Because it is not the same code to use.
Motomonster has 2 direction pins.

ciao, sto modificando il mio 2 dof da velleman e sabertooth ad arduino + 2 x BB-VNH3SP30
https://www.olimex.com/Products/RobotPa ... -VNH3SP30/

volevo capire meglio come collegare arduino a 2 di questi e se il tuo codice è valido per questi o va modificato.
Non vorrei però attaccare 2 fili solo per copiare ma vorrei capire un paio di cose se non ti disturbo:

quali ingressi analogici per i potenziometri sono da utilizzare per controllare 2 motori?
mi pare di aver capito che arduino funzioni con una tensione analogica (PWM) 0-5 v per controllare la velocità del motore e un altra uscita (digitale credo ON/OFF) che indica il verso di rotazione.
Questo è giusto?
Se è cosi come so quali uscite di arduino utilizzare per controllare il driver?
Esempio:
Ingresso potenziometro A1
Uscita PWM: (2 fili) GND e 3?, 5?, 6?, 9? 10? 11?????
direzione?????
Credo che dipenda da come arduino è stata programmata giusto?
Per semplificare la domanda posto una foto dei collegamenti e dello schema del driver
grazie in anticipo



Hi, I'm changing my 2 dof by velleman and sabertooth to arduino 2 x BB-VNH3SP30
https://www.olimex.com/Products/RobotPa ... -VNH3SP30/

I wanted to better understand how connect arduino to 2 of these and if your code is valid for these or modified.
I would not, however, attach 2 wires only to copy but I would understand a few things if you don't trouble:

that analogue inputs for potentiometers are used to control 2 motors?
I seem to have understood that arduino functions with an analog voltage (PWM) 0-5 v to control the motor speed and another exit (I believe digital ON/OFF) that indicates the direction of rotation.
This is right?
If so how do I know what arduino outputs use to control the driver?
Example:
Potentiometer Input A1
PWM output: (2 wires) GND and 3?, 5?, 6?, 9? 10? 11?????
direction?????
I guess that depends on how arduino is programmed right?
To simplify the application place a link and picture of driver circuit.
Thanks in advance

hello billo!

yes the olimex VNH3SP30 works like Motomonster VNH2SP30: 1 pin for PWM speed, 2 pins needed for direction
and so the code is compatible!

look at page 2/26 of the specs https://www.olimex.com/Products/RobotPa ... h3sp30.pdf
and just follow the pinout below:

Arduino /.. VNH3SP30 motor1
....GND <-> GND pin
.........5V <-> 5V
.....pin 4 <-> pin 5 inA motor1
.....pin 5 <-> pin 8 pwm1
.....pin 8 <-> pin 11 inB motor1

Arduino /.. VNH3SP30 motor2
.....pin 6 <-> pin 8 pwm2
.....pin 7 <-> pin 5 inA motor2
.....pin 9 <-> pin 11 inB motor2

Arduino / Potentiometers
.....pinA4 <-> center pin of pot 1
.....pinA5 <-> center pin of pot 2
.....pinGND <-> 0 ohm's pin potentiometer 1 & 2
.....pin 5V <-> 10k ohm's pin potentiometer 1 & 2

Grazie @RacingMat per la velocità e la spigazione molto chiara.
Ho completato lo schema seguendo le tue indicazioni, se ti va di dargli un occhiata mi dici se è corretto o ho sbagliato qualcosa.
L' unico dubbio che mi è rimasto è l' alimentazione dei driver ma dalle foto è molto chiaro.
Quale pin devo alimentare, 1 o 2 ?
Grazie ancora per la pazienza



Thanks @RacingMat for speed and very clear explanation.
I have completed the scheme by following your directions, so maybe it will be useful to other users.
If you want to give it a look you tell me if it is correct or I missed something.
The only question that remained was the power of the driver but the picture is very clear.
Which pin should I feed, 1 or 2?
Thanks again for your patience

I think that your link is false. Because a windscreenwiper motor isn't a stepper motor.

[billo2404]

scusa ma quello del tuo link e un VH2SP30 mentre quello del mio link è VH3SP30.
Non capisco cosa intendi dire

sorry but your link and a VH2SP30 while that of my link is VH3SP30.
I don't understand what you mean

[RacingMat]

@arne : I think it's fine, VNH2 and 3 drive DC motors (not stepper motors)
but I may have missed a point

@billo2404 : I cannot find the names of the pins on the board (1 and 2). The specs are about the chip and unfortunatle not the board itself
do you have a picture?
