Arduino Uno

Arduino Uno comes with a wide range of sensors and peripheral support like third-party libraries, providing a huge amount of free projects and resources online. For more complex and advanced systems, you might want to look for more powerful options in the market. Arduino Uno R2 replaces the AtMega328 with Atmega8U2 and the more advanced Arduino Uno R3 replaces the Atmega8U2 with Amega16U2. 

Defining Microcontrollers

Microcontrollers were brought to the electronics industry for making our tasks quick and easy and to condition our devices to work according to our needs and requirements. The Arduino Uno is one such microcontroller board that comes in handy for projects related to digital electronics, embedded systems, robotics, or IoT. Its open-source nature makes the board and software readily available for anyone to modify and optimize them for better functionality. 

Main Features

Holding a RAM memory of 32KB, the Arduino Uno features a USB interface, 6 analog input pins and 14 I/O digital ports for connecting with external electronic circuits. Out of these 14 I/O ports, you can use 6 pins for PWM output. 

Connectivity

With a USB cable, the Arduino Uno can be directly connected to the computer and is compatible with Windows, MAC or Linux Systems. The built-in regulation feature of the Arduino Uno manages the voltage when the device is connected to external devices. The Arduino Uno is also integrated with WIFI connectivity.

Bootloader

Arduino Uno's built-in bootloader allows for easy and convenient uploading of program on the board, eliminating the need of a separate burner for the same purpose.

Storage

To make the board store more data, a micro SD card can be added in the board. Conveniently, the Arduino Uno comes with a reset button that takes the whole program back to its initial stage with just a push of a button. This function comes in handy when hangups occur in the program. 

About Arduino

Arduino was established in Italy as an open-source hardware/software company as well as project and user community that manufactures single-board microcontrollers and microcontroller kits for digital devices. Arduino uses a cross-platform IDE (Integrated Development Environment) software for its devices, that is free to use and only requires basic skills to learn it.
