ArduinoThread | ⏳ A simple way to run Threads on Arduino

ArduinoThread is a C++ library typically used in Internet of Things (IoT), Arduino applications. ArduinoThread has no bugs, it has no vulnerabilities, it has a Permissive License and it has medium support. You can download it from GitHub.

Arduino does not support isolated parallel tasks (Threads), but we can make the main loop switch function execution conditionally and thus simulate threading with Protothread mechanism. This library implements it and helps you to:. Blinking an LED is often the very first thing an Arduino user learns. And this demonstrates that periodically performing one single task, like toggling the LED state, is really easy. However, one may quickly discover that managing multiple periodic tasks is not so simple if the tasks have different schedule. The user defines a Thread object for each of those tasks, then lets the library manage their scheduled execution. It should be noted that these are not “threads” in the real computer-science meaning of the term: tasks are implemented as functions that are run periodically. On the one hand, this means that the only way a task can yield the CPU is by returning to the caller, and it is thus inadvisable to delay() or do long waits inside any task. On the other hand, this makes ArduinoThreads memory friendly, as no stack need to be allocated per task.
