Arduino UNO: Pinout, Datasheet, Features, IDE and simulation
Arduino UNO (A000066) is equipped with an Atmega328 microcontroller, a USB interface, 6 analog pins, and 14 digital pins. It supports communication protocols such as SPI, serial, and I2C. In this detailed guide, we will explore the Arduino UNO, covering its pinout, features, simulation, datasheet, and programming environment (IDE).
History of Arduino UNO:
The development of the Arduino Uno began in 2003 at the Interaction Design Institute Ivrea (IDI) in Italy. Professors and students recognized the need for an easy-to-use, affordable microcontroller board to develop embedded prototypes. In 2005, David Cuartielles, Tom Igoe, Massimo Banzi, and Gianluca Martino started working on designing a new microcontroller board named “Arduino.†The main goals were:
â—Â Plug and play board. (Driver installation required)
â—Â Easy to program.
â—Â Useful for both beginners and advanced users.
â—Â Affordable.
â—Â Compact design.
