Power Pins
The power pins are used to supply the power needed for operating the Arduino. In case some external source like a jack is being used to drive the power then it can be connected to this PIN. The supply of power that each board can take varies from one design to another and it is necessary to know this range for the board that you are using. Some Arduinos don’t have the VIN pin since they only accept a regulated input, one such example is lililyPad
- 5V(Power Supply): This is the voltage that is used for driving components like the microcontroller on the board. This power can only come either from VIN or a source that can provide a regulated voltage of around 5V. Any voltage less than this will not turn the Arduino on.
- GND: This is known as the Ground pin and is used to set a reference level as the ground. This is automatically considered to be at the potential 0V.
Overview of the Arduino UNO Components
Arduino is an incredibly important part of modern-day electronics. The ease with which these Arduino boards can be programmed makes them the best choice especially when it comes to integrating them with large-scale projects. In this article, we will get an overview of the basic components that make up an Arduino board. This will include talking about the brain of the Arduino i.e. the microcontroller, the pins, and the power supplies.
