hi guys..
Im doing project on water level indicator, I have designed water level sensor using transistor BC547.(circuit is attached)
The LED glows when probes touches the water. the output of the sensor is given to microcontroller.
I need some 5v to drive the port pins. but sensor output is below 3 volts. what can i do to get 5v and if I can amplify it, please provide the amplifier circuit.
