Control Home Appliances Using Esp32 Bluetooth

Hi!! Welcome , Today we will make a project to control Home Appliances running on mains AC supply, using esp32 and an Android Application to connect with.

Things Required :

1. ESP32 DEVLOPEMENT BOARD

2. RELAY MODULE

3. JUMER WIRES OR CONNECTING WIRES

4. Purf Circuit Board or BreadBoard

The Circuit Diagram is very simple just connect the IO pins like this:

Relay Signal pins:

1 --->IO15

2 --->IO2

3 --->IO13

4 --->IO12

If u want to control more devices (even though diagram shows only 4 relays)

here are the pins

5 --->IO16

6 --->IO17

7 --->IO5

8 --->IO18

Now just connect your ESP32 and upload the code using Arduino

Code is there for Download !!! Just upload it to esp32

First turn ON Bluetooth and pair the esp32 with name "Rhee ControlSmart101" and then DOWNLOAD the app using the link from google PlayStore

Link: https://play.google.com/store/apps/details?id=com....

click on search button Choose the device and press connect button

Now try switching on and off device3 if Led on esp32 lights up (may vary on some esp32) it means its working and so should other pins work

And Now u have made your own System to Control AC mains Appliances
