Which pins to use?
I have tried TX RX ( prevents uploads of code through USB unless I disconnect them, upload the code and reconnect ).
7 & 8 redirected with -Swap which allows the code to be uploaded
Other recommendations on the internet were 0+1 2+3
What code to use; I have tried quite a few examples but unless I know I have the correct pins I do not know if the code is working!
My sensor is outputting a base 64 string five times a second and it is truncated with a CR. I am not particularly worried about this at the moment as even if I receive some gobbledygook I would be happy and can deal with it in the next stage.
Please could somebody put me out of my misery and confirm which pins I should be using and it would be helpful if I also had the simplest of sketches I had confidence in to read the output and display it in the Arduino serial monitor.
