    How many volts does an Arduino use?
    The recommended range is 7 to 12 volts. The power pins are as follows: Vin. The input voltage to the Arduino board when it's using an external power source (as opposed to 5 volts from the USB connection or other regulated power source). You can supply voltage through this pin, or, if supplying voltage via the power jack, access it through this pin.

    How do you read a voltage on an Arduino?
    If you need to read in a voltage on an Arduino digital or analog input pin, ensure it is between 0 and 5V. If it is outside these limits, you can bring down the voltage using a voltage divider. This scales the input voltage to allow for analog or digital readings of voltages otherwise outside the allowed range.

    How do I power the Arduino Uno & nano?
    Power Limitations of the Arduino Uno & Nano:Voltage Input Limits: Input power: to power the Arduino, you either plug it in to a USB port, or you input a voltage source to it either its 2.1mm x 5.5mm DC power jack (if present, such as on the Uno) or via jumpers going to its "VIN" and "GND" pins (which are on all Arduinos that I've seen).
