%X The success of the Arduino platform has made embedded
   programming widely accessible. The Arduino has seen many
   uses, for example in rapid prototyping, hobby projects, and
   in art installations. Arduino users are often not
   experienced embedded programmers however, and writing
   correct software for embedded devices can be challenging.
   This is especially true if the software needs to use
   interrupts in order to interface with attached devices.
   Insight and careful discipline are required to
   avoid introducing race hazards when using interrupt
   routines. Instead of programming the Arduino in C or C++ as
   is the custom, we propose using occam\-π as a
   language as that can help the user manage the
   concurrency introduced when using interrupts and help in the
   creation of modular, well\-designed programs. This paper
   will introduce the Arduino, the software that enables us to
   run occam\-π on it, and a case study of
   an environmental sensor used in an Environmental Science
   course.
