2. BC547 Transistors (4 no)
3. PC817 Optocuplors (4 no)
4. 510-ohm 0.25-watt Resistor (4 no) (R1 -- R4)
5. 1k 0.25-watt Resistors (5 no) (R5 -- R9)
6. LED 5-mm (5 no)
7. 1N4007 Diodes (4 no) (D1 -- D4)
8. Push Buttons (4 no)
9. Terminal Connectors
10. 5V DC supply

During the Arduino IoT cloud tutorial video, I have explained all the steps to make this ESP8266 smart home system with Arduino IoT Cloud to control the home appliances with and without the internet. I have also shown how to connect Google Home with Arduino Cloud to control the relays with voice commands. If the ESP8266 connected with Wi-Fi, then you can control the relays from anywhere in the world with the Arduino IoT Cloud mobile app and Google Home. And if there is no internet, still you can control the relays manually with buttons. So with this smart house project, you can convert any appliance to IoT devices and control them through the internet.

So, now you can just say "Hey Google, turn on Switch" to control the home appliances.
