First you'll need these components for the project. Which are :
3.BC 547 BJT-2 pieces
5. 9V battery
7.470 ohm Register-2 piece
8.220 ohm register-2 piece
Step 1: Circuit Diagrams
In the first picture I've shown you the BC547 BJT's pin configuration . And in the 2nd picture diagram is for Water Level indicator . There will be another pin from battery's positive terminal . If you don't understand click here to ask me on facebook .
Step 2: Circuit Diagram and All the Stuffs
Just follow the instruction of that video . It'll be very easy for you to get this project done .
