Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me.

G'Day Guy's, Well as I said in my inverter build thread trying to program a new nano is just refusing to work.
First tried on my shed laptop running linux and no joy the same with my shed computer running win10.
So just now on my house computer running win10 downloaded the Arduino software and tried to program the Nano with the lcd code as before and still no joy.
so got Nano selected as the board COM3 checked and working old bootloader used
clicked the first entry on the programmer list.
Now this worked on my old computers before they died so with a fresh install of the Arduino with a board connected on 3 of my computers why does it refuse to program.
Regards Bryan
Edit: just went and tried on my good laptop and got the error programmer not responding. This was the same error on the other computers too Edited 2026-01-19 14:47 by Bryan1

Well lets just say going from a 275A mig welder back to a soldering iron was the culprit with having no luck went and got a new nano and it programmed first time and when I used my phone camera to look at what the leds are for saw 2 solder globs shorting the pins. So used my solder sucker and tried again and it programmed Before the rx/tx leds were on and the arduino software went into a never ending loop.
