Oct 2, 2017 · Part 1 It is not usually long before new Arduino users discover that although the delay() function is easy to use it has side effects, the main one of which is that its stops all activity on the Arduino until the delay is finished (not quite true, I know, but that is usually how the problem presents itself). They use microcontrollers based on 32-bit ARM technology. Another solution would be to use an Arduino task scheduler like TaskScheduler. Arduino Multitasking Example. The vTaskDelay() sets the delay time for how long each LED turns on. 8, look for the FreeRTOS Library under the Type: “Contributed” and the Topic: “Timing”. Les tâches comprendront le clignotement de deux LED dans un délai différent avec un bouton-poussoir qui sera utilisé pour contrôler l'état ON / OFF de la LED.
