Now that you know what an Arduino is, let’s take a closer look at how it works. One of the most important parts of an Arduino board is its pins. Pins are small metal connectors on the board that you can use to connect electronic components like sensors, motors, and lights.

There are two main types of pins on an Arduino board: digital pins and analog pins. Digital pins can be used to turn components on and off, like a light switch. Analog pins, on the other hand, can be used to read information from sensors that give a range of values, like a thermometer.

Each pin on an Arduino board is identified by a number. The digital pins are numbered from 0 to 13, and the analog pins are labeled with an “A” followed by a number from 0 to 5. You can use these numbers to refer to specific pins in your code.

To use a pin, you need to tell your Arduino board what you want it to do. You can do this by setting the pin as an input or an output. If you want to turn on a light connected to a digital pin, for example, you would set that pin as an output. If you want to read data from a sensor connected to an analog pin, you would set that pin as an input.
