Basic DC Motor, with PWM (CCW & CW)

[Rafa75]

I want to share a basic code for PWM control with a DC motor, through a Shield (L293 & L298).

I Use a DFROBOT Shield.

My setup is Arduino uno R3, Labview 2010 on MacOS

This worked really well for me. Thanks!

You forgot to set the pin mode for all the digital pins.  I posted a cleaned up version and a solution to one issue here.

Can this be done with the adafruit motor shield 2.0?  I would like the accomplish the same functionality i.e. DC motor speed and direction control with Labview.  Not sure which digital pins should be used with this shield.

At the present time LIFA  provides support for using stepper motors with the Adafruit motor shield but not DC motors..  If you must use LIFA than you would need to add support for DC motors to the LIFA code. 

Or you could use the serial monitor capability of Labview to send commands to a sketch running on an Arduino Uno to control a DC motor.

Hi, I am asking whene I use arduino with the shield L298P it work fine, but with "NI MyRIO" It dosn't work at all ?
I tryed the simple way :

get the pins [4 5 6 7] at "High"

with "arduino" both of 2 motors turn with full speed and same direction

measurements: [3.4 v at pins 4 5 6 7]

with "My RIO" ... nothing happened

measurements: [3.1 v at pins 4, 7] and [2.8v at pins 5, 6].

any ideas guys

hi

can  you help me by  how  i can generat PWN  by using serial port (VISA)

arduino and labview
