Home Automation Using Arduino and Bluetooth is an IoT project to control our home appliances like light, fan, cooler, etc. from a Smartphone. In this project, we use Arduino Uno and HC-05 Bluetooth Module and we give the command from our smartphone.

We also develop our Android App using MIT App Inventor to control Home Appliances using smartphone and Bluetooth.
