13+ Arduino Nano Digital Pins Not Working Gallery. If your arduino has stopped working it's worth trying this. Do this at your own risk!
Act as a synchronizing clock. The digital pins can be used to interface sensors by using them as input pins or drive loads by using them as output pins. The pins working at the maximum input voltage of 5v.
The analogue pins are starts from.
If you do try it out then remember that programming the arduino is done over the serial link, i would imagine that any input to these pins during programming the. Pi to the nano with a 20k resisitor worked fine. Whether analog pins or digital pins work or not is not really a blynk specific issue… places expand upon your information so we can do more than take guesses. I'm checking the relay with esp and arduino nano.
