555 timer stands out as the go-to IC for most of the DIY needs and hacks. I have been using the 555 timer for quite some time and boy, it is so powerful.

But, I would like to share with the community on how to transform the 555 timer from generating mere square waves of required frequency, to generating frequency sweeps.( I call it the 'Sweep Mode' )
