hello !!
i'm quite new to electronics . i've got to use light sensors for a robot. can anybody please help me out in telling something about sensors . if possible please give the suggestable websites for gaining knowledge about it

 

Try going to the homepage of this website and click on the "links". There are three very interesting links that you can explore. The first of these will take you to a website that contains a number of interesting circuits. Among the list is a light sensing circuit.

Good Luck
