WS2812 Ring LED Clock With NTP Server Using ESP32

Introduction

Previously, I have shared on how to make NTP clock using dot matrix and ESP32. So, this time I would like to display on WS2812 ring LED. Maybe you can consider it as a Hari Raya clock! Before that, please read the following tutorial first.

• Dot Matrix Clock With NTP Server Using ESP32
• Send Data Wirelessly Between ESP32 Using ESP-NOW
