I am new to electronics and I see the I.C 555 timer everywhere. What is it and why is it so famous. I found it's price to be only 15 cents in an indian store ( 6 rupees). So cheap. but so famous. Where can I find more info about it. What is it used for. What projects can I do with it? ---Thaks in advance. :) P.S: Please point to any youtube vids that explain I.C 555 timer.
