I have knowledge in web and mobile programming.
I have a huge interest in learning Arduino and integrating my creations on the board with web and mobile systems.
My question is:
Is it worth messing with Arduino?
And if, for example, in Arduino I create something associated with my residence (lights, temperature ...), will the Arduino I bought be used for just that?
If I want to do another (new) project, for another purpose, do I need another Arduino?
