In this project, we will learn How to design a relay and HC-05 Bluetooth based Android Mobile controlled wireless Home Automation system with AVR ATmega16 microcontroller Part-I. Here, we will use the Android Mobile as the input device to control the appliances i.e 2 bulbs and 2 fans wirelessly.
The communication between HC-05 Bluetooth Module and Android Mobile takes place through wireless Bluetooth technology. And the communication between HC-05 Bluetooth Module and ATmega16 microcontroller takes place through UART serial communication protocol. The HC-05 Bluetooth Module and Android Mobile are connected through Bluetooth. User enters the control signal from Android Mobile through Bluetooth Terminal App and the Android Mobile transmits the control signal to the HC-05 Bluetooth Module through its bluetooth. The HC-05 Bluetooth Module receives the control signal and transmits it to the ATmega16 microcontroller through UART.
The ATmega16 microcontroller receives the control signal and processes it and sends the required control signal to the Relay Driver. Relay Driver will turn On or Off the home appliances according the control signal received from the ATmega16 microcontroller. The ATmega16 microcontroller also sends the appliance status to the Android Mobile through bluetooth.
Here, we will use 2 keys from the Android Mobile to control one appliance. One key will be used to turn on and the other key will be used to turn off the appliance. So, for four appliances, we will use 8 keys from Android Mobile. Apart from these 8 keys, we will use 2 more keys to turn on and off all appliances at a time. Now, press different keys from the Android Mobile and control the appliances as you want.
