It ' s difficult living in a world where people turn bi and charge their phones . I don ' t know how I ' ve survived this long . <| sep |> The stadium isn ' t a fucking car . <| sep |> Oh damn , I need to pick up the kids from soccer training . <| sep |> Looks like uTheBoomBoy beat me to one of my main points . The other is , the Arduinos genuine or not are a development or prototyping product . You shouldn ' t really be using a full blown Arduino in a commercial product . Heck , for personal projects it ' s a good idea to use the Arduino boards for just the development cycle . Once it ' s time to do the final product or end project , instead of using , say an Arduino Uno you use an Atmel 328 p chip and something like a DIP socketetc wired up and programmed ready to be put in situ . A lot smaller footprint and a lot cheaper than leaving the development board in your LED light fixture or whatever . The Pi Zero is also not technically a microcontroller . It is a SBC , a singleboard computer . The Pi Zero typically runs Linux , and programs , whereas the Arduino is a programmable microcontroller . The Arduino is also a realtime system , the Zero is not .
