# Cloud NeoPixel Control

Day 98 of the 100 Days 100 IoT Projects collection. Board: ESP32.

Control ESP32 NeoPixels from a Node-RED dashboard hosted on AWS EC2 over MQTT. Your lights, commanded from the cloud.

## How it works

A Node-RED dashboard hosted on AWS EC2 publishes color commands over MQTT, which travel down to the ESP32's NeoPixels. Your lights answer to a server on another continent — cloud-hosted control with the full round trip on display.

## What you'll learn

- Cloud-hosted control planes
- AWS IoT pipelines
- Remote lighting control
- Internet-scale latency awareness
