Abstract(s)

Although projects using Arduino boards are becoming more and more common due to their simplicity, low cost, and a variety of applications, Arduino boards consist of a simple processor that does not allow the execution of threads. This paper presents a study and evaluation of multithreading approaches on a single Arduino board. We present a group of existing software approaches for dealing with concurrent actions on Arduino. Among the solutions presented, we propose a case study using timed interrupts due to their simplicity. Although the case study provided requires dealing with many actions concurrently, including external actions, timed interrupts showed to be a robust solution to the problem. Furthermore, the evaluated approach presented great potential for being applied and implemented commercially at low cost.
