on video Automatic water-pump control circuit

today in this video i have shown how to make a simple automatic water pump controller circuit. This is a very useful circuit for household water tank. It's very simple too. The two wire from the relay should be connected in series with the" off " switch of the water pump. You can use iron or steel nail at the tip of the wire which goes to the water tank. Components required for this project:- 2N2222 Transistor(or any general purpose transistor) 220 ohm resistor relay Diode1N4007
