...If you don’t have components like sensors, Leds..., then this program will simulate the components for you. You need a real Arduino board for testing your programs with your computer.
You can drag and drop the components in a worksheet and you can draw everything you want around it. It is also possible to load a background into the worksheet. You can also combine simulated inputs/outputs from the pc and real Arduino IO, now you have made a little HMI (Human Machine Interface).
It's also possible to simulate through TCP WiFi-Ethernet connection.
