-Căutați pe Internet diagrama (pinout-ul) plăcuței de dezvoltare NodeMCU-32S pentru a afla PIN-ul la care este conectat LED-ul de pe plăcuță. Definiți constanta LED_BUILTIN folosind acel număr.
+Define LED_BUILTIN to correspond to one of the on-board LEDs.
+For the <color green>GREEN boards </color> (rev. 1) the LED has the following pinout
+  * Red - GPIO25, Green - GPIO26, Blue - GPIO27
+And for the  <color blue>BLUE boards </color> (rev. 2), the LED has the following pinout:
+  * Red - GPIO14, Green - GPIO13, Blue - GPIO15
