Arduino for ODROID-GO - Blue LED and PWM
Make sure that you've followed these guides.
Refer to the Arduino official documents. This tells us useful common functions
with great instructions.
Refer to the ESP32 official programming guide. Most of ESP32 specific functions
introduced here.
We don't need odroid_go.h library for this step.
You can implement the breathing effect as well by using fading functions in the
ledc.h. Not to be dealt with in this guide.
We will learn that how to control the blue status LED on the board and how to adjust PWM value to
give a breathing effect to the LED with Arduino.

Open a new sketch by pressing the shortcut CTRL-N. You're able to control that LED very easily. The pin number for the LED is 2. Define that with Preprocessor.
