In this tutorial we will learn how to use the cpplinq any operator to check if at least one element of an array fills a given criteria.

In this video we will be testing the code in the ESP32, using the Arduino core. Nonetheless, the code also works on the ESP8266, as cpplinq is a generic C++ library.
