Bluetooth Control Home Appliance Circuit Making with Perfect App for Android

Hello buddies, I am back with a new project, in this post I will show how to make Bluetooth control home appliance on-off circuit, means you can control your home appliance using your android mobile, I select a beautiful and stable app for android mobile, But you need to follow my video tutorial to set up the app otherwise, this project will not work. and I also design an 8 channel PCB board for you, so let’s start …

Component Required :-

1. 5v relay 8pcs
2. Atmega8a or Atmega328p ic
3. 28 pin ic base
4. 16 MHz crystal
5. BC547 transistor 5 pcs
6. 1n4007 diode 5 pcs
7. 3pin screw terminal connector 5 pcs
8. Led 6 pcs
9. 1k resistor 11 pcs
10. 2 pin screw terminal 1 pcs
11. LM7805 voltage regulator ( for 12v power supply)
12. Bluetooth module ( i’m using HC05)
13.1000uf/25v capacitor 1 pcs
14. Female header
15. Some wire

8 Channel Designed PCB Board

If you are giving 12 volt supply then
1. solder this jumper ( ‘1’ image below )
2. solder 7805 voltage regulator (‘2’ image below) to convert 12v -> 5v
