Arduino Nano ESP32 - Blink multiple LED

This tutorial instructs you through programming the Arduino Nano ESP32 to blink multiple LEDs simultaneously without relying on the delay function. Each LED can blink at a different frequency from the others. We'll use three LEDs as an example, but you can easily adapt the code to blink more LEDs.
