Enhanced ESP8266 Based WiFi Fan Speed Regulator

This instructable will guide how to make an Ceiling Fan Speed Regulator using Triac Phase angle control method. Triac is conventionally controlled by Atmega8 standalone arduino configured chip. Wemos D1 mini adds WiFi functionality for this regulator.
Featuring -
1. Both local and wifi controlled (Push button & Smartphone wifi).
2. State saving feature to resume fan speed level even after power interruption.
3. Low speed fan cut off (avoiding overheat of Fan stator).
4. LED Indication feedback for button push and speed level.
5. Standalone cheap Atmega8 DIY board rather than Arduino Uno R3
BE CAUTIONED THAT THIS PROJECT INVOLVES WORKING WITH DIRECT AC 220V WHICH IS HIGHLY DANGEROUS.”
