Water Level Indicator using BC548 Transistor (Mini Project)

Wow.. tats Gr8 bro.. By Doing this Project u might learnt how the transistor works nu...

Yes bro. Nice learning experience.dont forget to post about robotics.

@Srini : I tried this mini project and it worked.. and one more problem in implementing the project.... Next month i have Mini Project Exhibition in my EEE department and i was about to do this Water Level Indicator Project, but my professor said that i can modify the existing circuit by connecting IC to automatically Switch On the Electric Motor by connecting a tripper when the water in the tank becomes empty and instead of connecting the Buzzer, he said to Switch Off the Electric Motor... It is interesting and does not need a person to monitor the Lights and switch off motor when buzzer sounds and it also switches on when the tank becomes empty.... @Srini : I request you to post the circuit diagram for the above idea... Also other members can discuss about the updation of this mini project.... 
Thank you....
