ESP-IDF/Chaser

# Neopixel Chaser Example

This Example demonstrates the chaser effect: Neopixels are lit one after another in a chasing sequence.
Build and run in the `ESP-IDF` environment.

## Change the GPIO numbers

To keep things simple, the used GPIO pin and PixelType are defined at the top of `chaser_main.cpp`. Most probably you have to change this for your specific ESP32xx hardware configuration.

## Install and run

See the generic instructions in the neopixel/examples/ESP-IDF/README.md

The Neopixels will be lit one after another.

The VSC Terminal will show logging like this:
