In this project you can control 4 AC appliances and Speed of 1 ceiling fan using internet via Blynk and without internet via manual switches and fan regulator. This Same project will also work with other IoT Platforms like, Arduino IoT Cloud, Firebase Realtime database etc. For controlling the speed of the fan we have used capacitive dimming method. And also you can get real time feedback of switches and fan regulator on your IoT Platform.
