/*************************************************************************
Make sure to include the Adafruit NeoPixel library for ESP32 before
 compiling and uploading the code. Also, adjust the RING1_PIN and 
 RING2_PIN constants according to the GPIO pins you're using to 
 connect the NeoPixel rings.

The code includes two functions: chaseAnimation() for the clockwise 
and anticlockwise chasing animation, and blinkColors() for the
 blinking animation with different colors. The loop() function
  controls the overall animation pattern by calling these functions 
  for both rings. The animation cycles are repeated three times 
  for each ring.

Please note that this code assumes you have already
 installed the Adafruit NeoPixel library and have the
  necessary connections set up for the NeoPixel rings.
