In this video, Zahraa provides an overview of power pins that are used on the Arduino board.
- [Instructor] These are the power pins.…They're usually located in the left side…of the Arduino board.…The first one is a voltage in.…V-in and sometimes labeled nine volts,…use this input voltage when using an external power source…as opposed to the five volt from the USB connection.…An example is when providing a voltage…from external source like a solar panel.…Note that different boards accept different input voltages…so always check the documentation.…
The five volts, this pin outputs…a regulated five volts from the regulator…on the board to provide a voltage to your circuit.…We'll use this pin in our examples later in the course.…Three V three provides an output of 3.3 volts,…and finally, the ground pins.…So when we build a circuit, it's important…to have a common ground with Arduino,…and here where we connected.…
