WebHello, I am working on a project where I have to measure the voltage of a 24V/7mAh battery during its discharge. Given the number of measurements, I decided to use an Arduino UNO board to record them directly. I know that I should not apply a voltage higher than 5V at the input of the Arduino, so I will use a voltage divider bridge.
