Labview+arduino+DC motor

Nymar — Mon, 26 Nov 2012 22:08:47 GMT

I'm trying to control a dc motor through Labview and arduino...the problem is that i find stepper moto and servomotor in the librairies but not dc motor what to do please

In the functions palette Arduino > Low Level there are PWM functions. If the DC motor will only rotate in one direction then all you need is, these functions . If you need bidirectional rotation you will also need to use a digital pin to set the direction.

Thank you hrh1818 i was about bying a servomotor !! I'll appreciate more help about this topic at least how to start i'm new user of LabV...Could you please ??

You need to supply more information before I can provide additional guidance.

Who is the manufacturer and what is the DC motor's model number.

What Arduino shield will you be using to drive the DC motor.

Originally you said DC motor. Now you say servomotor. Do you mean a RC Servo?

What is the application? How will the DC motor be used?

ok here are the informations you asked

-I'm commanding a car and i'm using a motor for thepropulsion (moving forward and back ) and i think i will need a servomotor for the direction control

-the motor has nothing indicated on it !!

-i have arduino MDK because i want to command through android

Unless you have the Android communicating with LabVIEW, you can't use LIFA to do this.

Plese provide a link tothe surce for the car.

I don't see how you will gain anything by using Labview with your car , robot. If you will be using either either an Android Phone or Ttablet to control your car then the preferred communication medium is Bluetooth.

as i said i'm new with labview and arduino if i can't use them to do this project what do you suppose

Re: Labview+arduino+DC motor

Nymar — Wed, 28 Nov 2012 13:21:08 GMT

the car it's not from a store i don't have anything about it..i'm just taking pieces of it and i'm making mine what's the problem about communicating with android (arduino MDK) is made to do it no ??? if u can't help me with that i hope u help me with a tutorial or a screen shot of a labview code that command a dc motor through arduino it will be nice from u...just give me an idea about how to do it i mean how to use those pwm function and thanks for your time

Sorry, I can not help you, You haven't told me the make and model number of the DC motor yuou are using. I need this information to determine the current and voltage rating of the motor. Then based on current and voltage ratings I could recommend a motor shield to use with your Arduino Megs ADK and your DC motor.

The following information is not a recommendation. Howevr, the links can help you get started with your project

Here is a link to a typical motor shield.

<http://www.adafruit.com/products/81>

Here is a link to some bacgroud information and a "How To" for the Adafruit Motor shield.

<http://www.ladyada.net/make/mshield/use.html>

Here is a link to a clone of the Adafruit Motor shield.

<http://www.amazon.com/SainSmart-L293D-Shield-Arduino-Duemilanove/dp/B00813HBBO/ref=sr_1_1?ie=UTF8&qid=1354143978&sr=8-1&keywords=arduino+motor+shield>

The advatage of this clone is it is assembled. Whereas you would need to assemble the Adafruit Motor Shield. Adafruit Motor Shield clones are also available on Ebay at attractive prices.

the problem is that i can't find this motor shield in my country and i don't have the time to bring it from forign country....and i know u can't give me the exact code..but all i want is any code of any dc motor without using this motor shield the rest (current and the voltage) i will take care of. I know i ask u a lot but for the moment you are the only one who is helping me

To use Arduino to drive a DC motor you need a power amplifier. The power amplifier is connected between Arduino and a DC motor. It is used to amplify the very low level power output capability of Arduino to a value compatible with the DC motor's requirements. This could be something as simple as a transistor or as complicated as a motor shield. The code must be designed to work with a particular power amplifier. There is no such thing as generic code available for drving DC motors.

Here is a transistor example.
<http://arduino.cc/playground/Main/DCMotorControl>

Here is an example that uses a L293D IC

<http://luckylarry.co.uk/arduino-projects/control-a-dc-motor-with-arduino-and-l293d-chip/>

Here is an examle that uses a SN754410 IC.

<http://www.cla.purdue.edu/vpa/etb/resources/robotics01_SN754410_Arduino.pdf>

Notice the differences in code between the various examples.

For additional examples do a Google search on the phrase "Arduino DC motor".

You are really trying to help me but not with what i ask for...Look i already succeed turning on the dc motor with arduino my problem is LABVIEW !!!! how can i make the code and there is no predefined symbol for dc motors unlike servo motors and stepper motor you see ?

Re: Labview+arduino+DC motor

hrh1818 — Sat, 01 Dec 2012 01:46:16 GMT

You say:

"Look i already succeed turning on the dc motor with arduino my problem is LABVIEW !!!! how can i make the code and there is no predefined symbol for dc motors unlike servo motors and stepper motor you see ?"

I answered this question with my reply to your very first question. But you didn't tell me why this answer didn't help you.

Next I gave you a second chance when I asked You:

"Who is the manufacturer and what is the DC motor's model number.

What Arduino shield will you be using to drive the DC motor. "

You gave me a vague answer to the DC motor question but never answered the Arduino shield question.

Conclusion, based on the meager information you supplied the answer I gave to your first question is the best answer I can give. We are not here to teach you how to use Labview.

Look when i said i succeed turning on my dc motor i'm talking about yesterday i found it on google...and i'm not asking you to teach me labview i have ust one question i'm not asking the entire code....the question is simple in the labview palette i find sevo motor and stepper motor and there is no dc motor i googled it and there is no answer

Fooza2010 — Thu, 02 Mar 2017 17:30:31 GMT

hiiii all

i am designing some thing like CNC but works in x-y direction with power screw to get precise calculation and distances.I want to control steps and directions of 2 stepper motors NEMA 17 (4.2 kg.cm) with labview interfaced with arduino mega or uno (whatever).

what are drivers and components (resistor, transistors) needed ??

another what is difference between stepper dc motor and regular dc motor? is that controlling steps only!!

i have little experience of programing labview ANY HELP.

All of your questions can be answered by searching online since they are very common questions that don't relate to LabVIEW. I recommend that you search for your questions in the context of Arduino (not LabVIEW).

I think all he wants is what function to use on LabVIEW to start out.
