I need help with gpio pins states during boot. I know that 5V and 3.3V pins send this voltage once the board powers on. However I wish to know whether GPIO pins send by default 1/on or 0/off when the board is powered up. I might have seen somewhere that some pins outputs 1 by default and others 0 (most of them), but I don’t remember where I could see it.
Anyways, my goal here is: when I Nano receives energy, I need to send a ON/1 signal via GPIO and set it OFF when the boot is completed.
