Re: Question? UCN5804

Hi Koolmon

It depends what you are trying to achieve. If you want to learn how
to control steppers, there are plenty of resources out there. If
your final goal in something like a CNC or Robot, my advice would be
to bite the bullet and buy a stepper with its controller (Vexta) or
buy Gecko's for your already purchased motors. In summary, if you
want to learn the electronics, build your own circuit, if you want
to build a robot/machine, buy a controller

I do not know about your location, but your local electronics shops
or mail order (RS Components, Farnell, Digikey etc.)catalogue
company should stock those resistors. They are very common and
standard parts.
