Bluetooth 2 Relays Control Pro

Here is a simple Android Bluetooth Remote Control Project for 2 Relays / Device using 89c2051 Micro-controller and HC-05 Bluetooth Module.

You can download circuit and hex file here http://www.hobbyprojects.com/bluetooth-device-control/

App Instructions:

1. First make sure your HC-05 Bluetooth Module is paired with your mobile. The default password for pairing is "1234" or "0000". Check the manual of Bluetooth module.

2. When you press ON button for Device 1 it sends the data "A" to Bluetooth Module connected with a circuit. Microcontroller turns ON the Device 1 relay when it detects "A".

3. When you press OFF button for Device 1 it sends the data "a" to Bluetooth Module connected with a circuit. Microcontroller turns OFF the Device 1 relay when it detects "a".

4. When you press ON button for Device 2 it sends the data "B" to Bluetooth Module connected with a circuit. Microcontroller turns ON the Device 2 relay when it detects "B".

5. When you press OFF button for Device 2 it sends the data "b" to Bluetooth Module connected with a circuit. Microcontroller turns OFF the Device 2 relay when it detects "b".

应用说明：

1.首先要确保您的HC-05蓝牙模块搭配您的手机。对于配对的默认密码是“1234”或“0000”。检查蓝牙模块的手册。

2.当你按下按钮装置1发送与电路连接的数据“A”到蓝牙模块。微控制器接通它检测到“A”时，该设备1继电器。

3.当你按下OFF键设备1发送数据“a”到蓝牙模块与电路连接。单片机熄灭它检测到“一”时，该设备1继电器。

4.当你按下按钮装置2发来的电路连接的数据“B”蓝牙模块。微控制器接通它检测到“B”时，该设备2继电器。

5.当您按下OFF键设备2发送的数据“B”蓝牙模块与电路连接。单片机熄灭它检测到“B”时，该设备2继电器。
