Hello, I am doing an Arduino project using Arduino Mega and a 5V cellphone powerbank. I need to make the Arduino measure its Vin voltage in order to print the powerbank's battery percentage. How can I do this? How should the circuit and code be? I have read about voltage dividers but I don't know wh…
