TINKERCAD is a free, amazing, and user-friendly app for 3D design, electronics, and code for both professionals and non-professionals.
Thomas LawLy, a great teacher in engineering, introduced me to Tinkercad. I was baffled by the perfection of the application; it had everything I needed for my upcoming projects. At the same time, the app also includes Arduino, an open-source electronics platform based on easy-to-use hardware and software, something I've never heard of, but that surprised me by its diversity. With both of these, things are almost exclusively limited by human imagination. Everything can be set up, from a small circuit to control the lamp or simply turn on and off a light bulb, to more complicated than to control a production chain or even a robot.
Not to mention, the coding is relatively simple, even for an amateur with little experience, because it only involves clicking and dropping on the coding system of tinkercad. Most, if not all, the types of codes you can imagine are in tinkercad's system; all you need to do is search and programming for the machine you are manufacturing.
Besides, you can completely simulate a perfect prototype based on creating a 3D model with the entire circuit inside simply in Tinkercad if you know what you are doing. Even if you don't know, there are tons of videos, articles, and even teachers ready to teach you everything you need. However, we still can not deny that getting into Tinkercad is easy, because it is an extremely versatile application, so if you are a new person, it may be a bit overwhelming, so learn. Ask slowly, and everything will become more comfortable as you become a tinker master. Good luck

Here is my simple, adjustable lamp circuit for my recent project.
