Different types of Arduino boards available

 Arduino boards are available in various sizes and shapes to cater to different project requirements. Here are some of the most common types of Arduino boards:

1. Arduino Uno: This is the most popular board and is recommended for beginners. It has 14 digital input/output pins, six analog inputs, and a USB connection for programming.

2. Arduino Mega: This board is similar to the Uno but has more digital input/output pins (54) and more memory.

3. Arduino Nano: A smaller version of the Uno, the Nano has a compact size and can be used for smaller projects. It has 14 digital input/output pins and eight analog inputs.

4. Arduino Due: This board is designed for more advanced projects and has a 32-bit ARM processor, which makes it faster and more powerful than the other boards.

5. Arduino Leonardo: This board has a different microcontroller compared to the Uno, which allows for more advanced features such as emulating a mouse or keyboard.

    There are also various Arduino-compatible boards available from third-party manufacturers that offer additional features and capabilities. When selecting a board, it's important to consider the specific requirements of your project and choose the board that best fits those needs.
