Arduino Uno Description
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 Uno is a microcontroller board powered with the AVR microcontroller AtMega328. 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. 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.
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. With a USB cable, the Arduino Uno can be directly connected to the computer and is compatible with Windows, MAC or Linux Systems. To make the board store more data, a micro SD card can be added in the board. The built-in regulation feature of the Arduino Uno manages the voltage when the device is connected to external devices. 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. 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.
If you are looking to make your first break into microcontrollers, the Arduino Uno is your best bet as it is economical, very easy to use and has more academic applications. It 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.
