Home Automation using Audraino uno

           Hey friends I am here to introduce the 

                  Home Automation Sytem

                                Using Audraino uno

Required items :-

1. Audraino uno https://amzn.to/3Rx021g
2. Bluthooth module HC-05https://amzn.to/3aKDc5S
3. D - type Cable https://amzn.to/3Rx021g
4. phase and Netural wire 2-3 metre https://amzn.to/3O6ELsx
5.  Male to female jumper wireshttps://amzn.to/3POUn5h
6. Relay Modle (as per you home applinces) 

1 channel relay https://amzn.to/3AUQKGE

2 channel relay  https://amzn.to/3uRGo6i

4 channel relay https://amzn.to/3uSF6rU

8 channel relay https://amzn.to/3AUQS96`

• Buy relay as per your need of applines and voltage ampere taken by applinces
