Hi Govindraj,
I would suggest you to try helping forum members with their technical queries rather than demotivating them.
Hi Gavi,
Please post the kind of current sensor which you are using. Most of the sensors can be directly connected to the analog pins, but there could be exceptions.
Never drive a load directly using the microcontroller output pin. Use a driver circuit according to the load. You can make a driver circuit using a simple transistor or there are driver ICs available like lm2004.
