already set up the bootloader before uploading Blink and my own programs.checked all components and connections with multimeter, as mentioned above.(using a 220ohm resistor for a 20mA/2-2.2V orange LED) the resistor works fine - I even checked by connecting the LED to the 5V pin, which powers up fine and runs the LED no problem.the LED is properly positioned re: +/- ends & lights up when connected to power (besides the problematic pins of course).Yet, when I try to run Blink or my own programs with external LEDs, nothing happens. I even found the schematics for the Nano and tested the connections between the square chip on the nano and the pins - those appear to be functional too. I've tested all my external components with my multimeter (breadboard, LED, resistor) and they're working fine. I was able to get one working with Blink - the onboard LED works great! - but when I try to run any external LEDs, with the Blink pin (13) or with the other programs and pins I've tried (primarily 6 and 8 as I already soldered some breadboard pins for my current project). So, I got some Nanos (the Elegoo version, this set ELEGOO Nano V3.0 Compatible With Arduino IDE (x3) – ELEGOO Official). I made a really foolish mistake because of how I read the Pinout.
