Use the Arduino Leonardo microcontroller board in your schools’ makerspace or tech hub to teach students about programming and electronics. It contains everything needed to support the microcontroller. Built-in USB communication means there’s no need for a secondary processor; Arduino Leonardo can appear to a computer as a keyboard or mouse. Download the free, open-source software for project inspiration, or to let students experiment with their own ideas. Visit for a free getting started guide and project tutorials.
