Arduino Uno Configuration

Arduino Uno is one of the most popular and widespread MCUs (Microcontroller Units). It has 6 analogue inputs, and 14 digital input/output pins, of which 6 can be used as PWM (Pulse Width Modulation) outputs to emulate analogue signal. It also has a 16MHz ceramic resonator, a USB connection, a power connector, an ICSP (In Chip Serial Programmer) input and a reset button.

Before starting the Arduino Uno setup, make sure you have the following items:

• A desktop or laptop computer with an Internet connection.
  
  
• A USB cable (Type-A to Type-B)

The Arduino software (IDE)

The Arduino software is the Integrated Development Environment that allows you to write and upload programs to the MCU. There are two ways to work with the Arduino IDE:

• Arduino Web Editor: cloud storage, guaranteeing backup and access from any device. When working online, you always have the most up-to-date version of the IDE and the public libraries generated by the community (Libraries are a collection of codes whose objective is to facilitate interaction with modules, sensors, etc.). Arduino Web Editor requires a stable Internet connection.
  
  
• Arduino Desktop IDE: It allows you to work offline. However, it is necessary to perform periodic updates to ensure that you have the latest version of the IDE and the libraries (An Internet connection is required to achieve the updates). Arduino Desktop IDE is available for computers or laptops with Windows, Mac OS X, and Linux operating systems. The Portable IDE version allows you to install the application on a pen drive. The Arduino Create Chrome App version is available for ChromeOS.

Connecting the Arduino Uno

Arduino Web Editor

Arduino Web Editor allows you to write code and upload sketches to the Arduino board using a web browser (Arduino recommends using Google Chrome).

The web editor automatically recognizes the Arduino board connected to the PC or laptop and configures itself automatically.

Perform the following steps to start:

●     Create an account in Arduino Web Editor (you can create it by clicking here).

●     Open the web editor by clicking here.

●     Install the Arduino Web Editor plugin by clicking here.

After finishing the plugin installation, connect the Arduino board to your computer or laptop using the USB cable.
