1  Using Arduino / Interfacing w/ Software on the Computer / Re: Maxuino_b016 + ArduinoUno + Easydriver + Stepper motor on: February 22, 2014, 12:10:55 pm
Hello to everyone
I'm trying to use ArduinoUno+easyboard+ Stepper Motor – NEMA-17 – 48mm – 42BYGHM809

I followed these steps.
I'm running OS X 10.6.8 with Arduino 1.0.5

Download clean copy of Arduino 1.0.5
Download arduino-configurable.zip
Rename anrduino-configurable folder to Firmata
Replace existing Firmata library in Arduino application
Open Arduino application
Open File -> Examples -> Firmata -> ConfigurableFirmata
Compile (no errors)

then I uploaded ConfigurableFirmata to arduinoUno.

I opened the maxuino.maxhelp and finally WORKS WELL!!!!!!!!!!!!!!!!!!!

THANKS

1 x Stepper Motor – NEMA-17 – 48mm – 42BYGHM809
But what color is it? I'm not impressed by people who think that the mounting hole standard (NEMA 17) tells us squat about the motor that they have.

Now I need to use MAXUINO + StandardFirmata
No, you don't. Why are you under the impression that you do?

I  read that : http://www.maxuino.org/getting-started
Arduino Instructions:

Depending on your board you might need to install a driver for the serial port. (see http://arduino.cc/en/Guide/HomePage )
Connect USB cable to Arduino and your computer.
Start Arduino software.
Select your board from Tools -> Board
Select your Serial connection from Tools -> Serial Port
Open the Firmata program by going to File -> Examples -> Firmata -> StandardFirmata
Upload the Firmata program to your board by pressing the upload button or File -> Upload
When the upload is finished, you can close the arduino software.
Never have to learn to program Arduinos! (unless you want to)
Add your desired inputs or outputs to your board (look at tutorials like these for how to wire them http://arduino.cc/en/Tutorial/HomePage but you can ignore the programming since you are using Firmata)

Code:
I don’t understand how can I use the Stepper Motor Controll subpatch.
You lost me, there. What's a subpatch?
I found this subpatch // I enclose a photo

Now I need to use MAXUINO + StandardFirmata
- Arduino software: version 1.0.5
- Maxuino: version maxuino_b016
- StandardFirmata : version 2.1
But I have a problem because it doesn’t work.

I don’t understand how can I use the Stepper Motor Controll subpatch.

I mean how to configure it.

If someone have some ideas, any advice, tutorials, links are welcome.
Thanks

Ciao e grazie mille della pronta risposta.

Se non ho capito male l'Easydriver limita la corrente quindi con un alimentatore come questo non dovrei avere problemi.

Mi sbaglio?

Sono alla ricerca di informazioni utili per utilizzare correttamente tutto quanto.

Ho dei dubbi riguardo l'alimentazione che devo dare al motore ed anche quali siano i cavi del motore corretti.
mi sembra che per il
"motore 1" siano il BLU e VERDE
mentre per il "motore 2" ROSSO e NERO
qualcuno ha lo stesso motore?
Ho provato tutte le combinazioni di cavi utilizzando un'alimentazione di 3 e successivamente  12V con 600mA
ma non da segni di vita.
Ho utilizzato questo tutorial per il codice:

https://www.sparkfun.com/tutorials/400  

Se qualcuno ha delle dritte, vi sarei grato.

Thanks MarkT,

 Could you tell me a good engine with ball bearings?

If you had my same needs what would you do?

Hi and thanks for the replies,

MarkT, for "moves slowly"  = 10-12rpm MAX to 1rpm MIN , approximately.

I saw and red :


"... On a regular servo, the value controls the location itself. What you could do with a regular servo, is increment the value in steps, and add a delay in the loop, but that would only slow it down. I don't know of its possible to increase the max speed... "


:::::::::::::::::::::

fungus, we already have these stepper motors, but they aren't enough strong, I think that because they will be too slow.

http://www.hobbycomponents.com/index.php?route=product/product&product_id=170

If someone have some idea, for me there aren't any problems to use any type of motor can be controlled by Arduino.

Where can we find at a good price ?
(We are in italy/ europe anyway)

////////////////////////////
We need 10 of that… 
Something like this: https://www.sparkfun.com/products/9238 , perhaps he could operate?
Holding Torque : 2.3kg*cm are enough?


But it is dear!

Ciao to everyone,

we are lookig for a servo  360°.

The servo motor will be attached to the ceiling and we need that moves slowly.(a sort of ultraslow Ceiling fan)

We should use it to move an object that is distant about 50 cm and weighs 300g.

We are planning to use an aluminum bar of 50 cm, to which end is linked to the object.

Or use a bar of 70-100 with a counterweight of 300g or less ,  moving the central axis, obviously.

But the problem is …

Which servo motor is indicated for our purposes?
What kind of technical characteristics must have?
Where can we find at a good price ?

Hi to everyone,

Can we use a single computer to speak simultaneously to 10 arduinos via bluetooth?

We would like to use these  HC05 //  RS232  http://www.ebay.it/itm/Wireless-Bluetooth-Transceiver-Module-RS232-TTL-X2PCS-/190433073764?pt=LH_DefaultDomain_0&hash=item2c56b21a64#ht_6798wt_1165

We would like to have an independent control for each of them.
 

Thank You
Greetings

Mi scuso, non era mia intenzione recar disturbo.
Ho provato a chiedere anche qui solo perché mi pare il luogo più adatto,
e con alta concentrazione di esperti !

Grazie mille dell'aiuto datoci sin qui.

Salve a tutti,

stiamo tentando di capire quale sia la miglior strada per comunicare da un Mac

  Nome modello:   MacBook Pro
  Identificatore modello:   MacBookPro1,1
  Nome processore:   Intel Core Duo
  Velocità processore:   2 GHz
  Numero di processori:   1
  Numero totale di nuclei:   2
  Cache L2:   2 MB
  Memoria:   2 GB
  Velocità bus:   667 MHz

a una decina di moduli cloni arduino.

Ogni arduino ha il solo compito di controllare due stepper motors, tutto funziona senza alcun problema via USB anche con 2 cloni arduino attaccati.

Il progetto prevede però una decina di cloni.

Vorremmo poter comunicare via bluetooth simultaneamente con tutti utilizzando un computer.

1) E' possibile farlo con cosi' tanti moduli ?

2) I moduli HC05 sono adatti al nostro scopo ?

Se avete suggerimeti consigli, etc son ben accetti.

Grazie
Onde

Salve a tutti,

vorremmo utilizzare questo modulo  V2.0 RS232 TTL Transceiver Module http://dx.com/p/wireless-bluetooth-rs232-ttl-transceiver-module-80711

per la comunicazione bluetooth tra un mac e arduino

abbiamo 2 domande:
 

1 cosa bisogna fare affinché arduino riconosca il modulo una volta collegati opportunamente i pin rx e tx

2 è possibile usare un solo computer per parlare contemporaneamente a 10 arduini via bluetooth?

Ringraziamo
Saluti

15  Using Arduino / Interfacing w/ Software on the Computer / Communication between Maxuino and Multiple Arduino Boards on: June 03, 2013, 10:34:06 am
Hi All!

In our project we have to control 20 stepper motors. Each pair of stepper motors is connected to an Arduino Uno board, so in total 10 boards.

Our question is:

is it possible to communicate from the same Maxuino patch with multiple Arduino Boards connected each one to an USB port?

And:

if we want to have a wireless connection between the computer and the Arduino Boards, what can be the solution?

Thanks in advance to all!
