How this Smart Bell works ?
Here we use a single channel RELAY , an ARDINO NODE 8266 , VEETEX electric bell .
For the power supply we have a DC power supplier and also a AC power supplier.
We can operate this bell through our smart phone ( any web browser) .
The backend programing of this bell is done in C language , html , CSS , Jawa . To control it through our devices
We can replace this smart bell through our OLD STYLE bell .
