To play with 220V , we should be a little careful and need to take all precautions with testers to check to 220v supply.
This experiment we need to have Raspberry Pi ( already we have) and Relay Board which actually drive the switch and break the ciruit based on the 7th Pin voltage in GPIO pin.
Programs which we are gointo use same the Pyhon program we used to blink the LED from Flask python webpage
Only difference we used the Raspberry Pi GPIO pins 5v(2nd pin),Ground(6th pin), 7th pin to drive the relay a shown in the pictures.
