This Arduino project demonstrates the use of a counting semaphore in FreeRTOS to control access to limited hardware resources. Five tasks attempt to use three LEDs simultaneously.

Create your own Supla device! This software can be used as a library for Arduino IDE, or can be used directly with ESP8266 RTOS SDK and with ESP IDF. It is also possible to compile and run it on Linux ...

The Arduino ecosystem is an amazing learning tool, but even those of us who love it admit that even the simplified C Arduino uses isn’t the ideal teaching language. Those of us who remember ...

In this paper, we analyze the working principle of an arduino. These days many people try to use the arduino because it makes things easier due to the simplified version of C++ and the already made ...
