Error using arduino (line 104)
Connection unsuccessful, please make sure that the board is powered on, running a sketch
provided with the package, and connected to the indicated serial port. You might also try
to unplug and re-plug the USB cable before attempting a reconnection.
Hi Colm, you should probably connect a good external power source to the motor shield.
Anyway, in the version1 of the motor shield library the stepper commands are blocking, so, while you can have 2 stepper connected, you can only operate them one at a time, not both at the same time.
I think (but I am not sure) that the same is true for the version 2 of the board.
Note that instead you can run up to 4 DC motor simultaneously since DC motor commands are not blocking.
I am using the ArduinoIO package and a Adafruit Motor Shield with 2 motors. I am having a little difficulty powering the motors. Is there anyway of having two simultaneous stepper motor outputs?
Thank you in advance
nearest neighbor algorithm does not guarantee optimality. See JVC algorithm.
