Hello forum, I am experimenting with Arduino reading voltage with a 10k resistor. I have successfully done that but I realised I can’t use power when the mini USB cord is not in the Arduino Nano. I would like to use it when it is not plugged in like a lcd screen or anything else. I would only like …

SOLVED Thanks everyone I worked it out, using a voltage divider. I had 2, 1K resistors in series with it connected to VIN and ground. [image] CASE CLOSED

Not sure I get the question

Do you plan to power your Arduino Nano with 3V?
