555 Useless Machine

Almost every project that I made in my life use arduino or just atmegas, but on last electronic lesson in my school I found small integrated circuit called 555. I have heard about it before but I was thinking that microcontrollers are better. I read something about 555 in the internet and I found that this is the most popular integreted circuit in the world! And I have never used it :( I thought that it can be nice to make something completely without any programing and just with basic electronic components. I started to think what can I do with 555, but couldn’t find anything intresting. Than I talked with my friend about useless machines and I thought that I can make useless machine with 555, servo, some resistors and switch. And it will be very simple and I don’t need microcontroller to make it! I order some 555 on the internet and thought that I can test my design in some simulator. In school we are using electrosym but it’s very old and I don’t like it. But I read about circuits.io and I thought I will try it, after testing everything I can say that this program is pretty good to start with, it’s simple to use and very intuitive. Additionaly it looks soooo good like every autodesk’s program :)”
