Arduino

Which Arduino suits my project?

The suitable Arduino development board depends on what you are building. Arduino Uno is a good general-purpose option and is especially suitable for first Arduino projects, education and prototyping. Arduino Nano is a smaller option for situations where board size matters, while Arduino Mega offers more connectors for larger projects.

If the project requires Wi-Fi or Bluetooth connectivity, you should choose a development board with wireless connections built in. For example, in network-connected IoT projects this reduces the need for separate add-on modules.

What to consider when choosing an Arduino?

• Number of connections: how many sensors, motors, displays or other devices will be connected to the project.
• Board size: Nano-series boards are well suited to compact implementations.
• Performance: more demanding projects can benefit from a more powerful microcontroller and more memory.
• Wireless connections: Wi-Fi and Bluetooth are useful for IoT, automation and remote control projects.
• Expandability: shields, sensors and other add-ons allow you to expand the features of the development board.

What is needed for an Arduino project?

To start a simple Arduino project you typically need a development board, a USB connection for programming and, depending on the project, sensors, LED lights, resistors, motors or other electronic components. For beginners a ready-made Arduino starter kit is an easy way to get started, as it includes the development board along with components and exercises for building various projects.
