Playing with arduino without hardware

by
tinkercad

 

This is my video 3 years ago, but I think this is always a fun way to play with Arduino, you can do it everywhere, and every time you want to test something with Arduino, with tinkercad you can interact with sensors, passive component, power supply, and so on.

It is convenient if you have an idea in your mind and want to test something but you don’t have hardware around you, with simple drag and drop and also interaction with buttons etc, you can have the feel as you do with real hardware

If you are a student, or hobbyist who likes playing and programming with hardware you must try tinkercad, it is free and web-based, you only need an internet connection to play around
