16  Topics / Robotics / How to change 5 DC volts from Arduino into +/- 5 volts on: February 09, 2013, 07:33:32 am
Hi everyone:
I would like to ask you how is it possible to change the output voltage from arduino (5 DCV) into a +/- 5 DCV?
Thank you for your help.

18  Topics / Robotics / Re: DC motor position control using potentiometer - HELP! on: January 23, 2013, 11:41:48 am
The position of the DC motor should be detected by the potentiometer.

Yeah ! exactly !
But I dont know if that is possible with the things I have.

Hola a todos:
Quisiera preguntarles si es posible, solo teniendo un motor DC y un potenciometro colocado al final del eje de giro, obtener el modelo matematico del motor DC. El potenciometro gira de 0 a 300 grados y cuando probe el motor a penas le puse 3 voltios no se cuantas vueltas dio. eso es mas de 300 grados podrian ayudarme con este problema.
Cordiales saludos.

Hi there:
I would like to ask you if it is possible to obtain the mathematical representation of a DC motor using a potentiometer connected to the motor shaft and Arduino UNO board.

Technical Parameters:
the potentiomer can be turned from 0 to 300 degrees.
DC motor voltage 7V.
Arduino UNO board.
Motor shield.

Can somebody help me with this?

Pues me parece que seria bueno que uses una protoboard y pases el ground a ella y lo mismo podrias hacer con el voltaje del pin. Y pues en la protoboard podrias poner tantos piezos como gustes.
saludos amigo
23  International / Hardware / Control de posicion de un DC motor usando potenciometro - URGENTE !!! on: January 22, 2013, 02:06:22 pm
Hola a todos:
Alguien me podria ayudar con el siguiente proyecto. Necesito probar un controlador PID para el control de la posicion de un motor DC. El sensor que debo utilizar es un potenciometro, el cual puede girar desde 0 hasta 300 grados. Dicho potenciometro debe ser colocado al final del eje del motor.
En este proyecto debo de usar la motor shield para Arduino y la placa Arduino UNO.
Por favor necesito ayuda urgente. Se como funciona el controlador PID, pero no tengo ninguna experiencia en electronica. Alguien me podria explicar paso a paso lo que debo de hacer. Se lo agradeceria muchisimo.

Hello there!
I would like to ask you if there is the possibility to control position of a DC motor using a potentiometer connected to the motor shaft.
Can somebody explain me step by step how to do this ????, it is the first time I'm working with Arduino. I know how a PID controller can be applied.
I have to use the following materials:

DC Motor (7V)
Potentiometer (I can turn it from 0 to 300 degrees)
transistor
diode
resistor
External adapter
Motor shield for Arduino

Please I need your help urgently.
Thank you for reading this message.

Thank you guys for your responses smiley) I'm going to work on it.
26  Topics / Robotics / piezoelectric actuator - ARDUINO on: January 14, 2013, 10:21:42 am
Hi :
I want to test a piezoelectric actuator using Arduino. The question is : For testing the piezoelectric actuator I need AC voltage between -2 to 2 volts.
is It possible to do that test using Arduino????
Thank you for your advice.
27  Using Arduino / Motors, Mechanics, and Power / How Can I read the input voltage into a DC motor using Motor shield ?? on: January 14, 2013, 10:00:35 am
Hello smiley
I would like to read the input voltage into a DC motor using Matlab. I'm new using ARDUINO with the MOTOR shield.
I hope there is someone who can help me with this.
Thank you.
