Richard Hayler’s primary school Code Club has recently been selected as one of the winning entries in the Astro Pi competition. Their code is one of the projects that will actually run on the International Space Station! It uses the Astro Pi to detect changes in humidity near the Astro Pi board, thus detecting the presence of an astronaut. Richard has written up their experiences developing the software, including a rather impressive LEGO version of the actual case. Read all about it here.
