This is sooo cool!
On and off just with a single click!
Earlier in my +2, I had made a sound intensity-controlled LED switch wherein the intensity/volume of the sound will decide how dim/bright will the LEDs light up.
How easy will it be for me if I start making this project?

Post the details here. We could make a guess about how much effort you will need.
Easy or hard is merely relative.
Besides unless you take the first step the journey will never begin.
Start by asking questions here. It will be a perfect exercise for everyone following this thread.
