Description: 1. Compatibility: Arduino Leonardo R3 is an input-output (I/O) board based on the ATmega32u4 microcontroller, which is fully compatible with Arduino Leonardo series and also backward compatible with Arduino Micro and Arduino Pro Micro. 2. Keyboard and Mouse Emulation: This board offers unique features of keyboard and mouse emulation through its USB connection, enabling it to act as a human interface device (HID), making it suitable for projects involving interactive art installations, multimedia controllers, or even DIY computers. 3. Programming: Arduino Leonardo R3 can be programmed using the Arduino IDE, an open-source software that supports both C++ and visual programming languages (like Scratch or Blockly). This allows users with different skill levels to work on projects effectively. 4. Input/Output Pins: The board features 20 digital input/output (I/O) pins (of which 7 can be used as PWM outputs), 14 analog inputs, and a USB connection that acts as both power source and commu
