Re: Raduino not working 0 Volts on Pin 6 (red wire) #ubitx #ubitx-help

These might not apply to Rogier's issue, but since I have already typed this up, it may be still helpful to him or someone else.

I had 2 issues when trying to connect to the supplied Nano on the Raduino board to my Windows 10 machine.
1. USB connection.   I started with a cheap working cable (that I use with Segger J-link debugger boards all the time) and did not get a power connection.
    Fiddled around on a Friday evening, I am aware that the USB connector on the Nano clone board may be an issue. (socket + connector tolerance)
    With the right pressure from the thumb, I could get intermittent connection.  OK, making progress.
    Went through the stash box and found a 'better' (well at least more expensive) USB cable with ferrite chokes on either end, that made solid connection.
2. Driver. (nothing found on PC comport)  Well there had been some discussion of issues with Macs (that wasn't forefront in my mind at this time) 
   With hesitation, I downloaded a CH341 driver for Windows.
   (installation complained about not being successful, but the driver was working)

Now I was up and running. Time for an adult  refreshment, sofa and bed.
Project gets side tracked for other things.  When I get back to playing with the Nano clone,  What do I do?  Use my everyday cable.
It doesn't work. Momentary lapse of sanity.  Get the 'better' cable and all is O.K.

This was the first time I played with a Nano clone.  My only experience with Arduino is the Uno R3.  I use them often for adding quick instrumentation, remote pin control of hardware under test, etc.
Clones are cheaper and make sense to use in various projects, like this one.  
However, If your budget allows, I'm an advocate of having at least 1 of the mainstream top tier manufactured products when you are self teaching.
Having additional obstacles to overcome when your intent is to 'learn Arduino' can be frustrating.
