Hy, This is one of my favourite projects because it is easy to make and needs a very few things. Mind it that I have not Invented it. Just made it by the help of other websites. As the current from the electrodes flow to each other through water and earth is provided the transistor gets charged and turns the led or the buzzer or whatever you have attached. I hope you like it.                                                                                                                                                  

Step 1: Supplies

Transistor BC 547   (2)
Led                          (2)
LDR                         (2)
Jumper Wires
Resistors :- 1k, 470 KR
Buzzer                    (Optional)
great job trying do one too <br>
Nice job! <br> <br>A schematic of the circuit would be informative for anyone that wants to duplicate your project, or expand on it.
Thanks. I would definitely put up a video after my exams.
very good circuit dude.i'm 13 now and i also started when i was about 11 years old.once you understand how components work,you'll start to get really interested.as for learning more about electronics i recommend-make:electronics,electronics for dummies,electronics demystified etc. <br>oh and are you from india? <br>
Nice work! I'd love to see you incorporate this into a vase or something so you know when your water level is getting too low. Maybe bamboo or something that can sit immersed in water for long periods of time.
