Don’t feel like digging out the Arduino and breadboard or even the soldering iron to try out a routine? Post-material handicrafts with popular microcontroller boards such as Arduino Nano, Uno, Mega, the Raspberry Pico or even the common ESP32 modules are possible Wokwi, a simulator that also offers various peripherals such as LEDs and displays for virtual wiring. There is detailed help for all available virtual components and modules, including information on compatibility with real hardware. As is usual with cloud-based services of this type, your own projects are only saved online.
The online simulator, which can be used free of charge, comes from CodeMagic LTD from Israel. Those with Arduino experience hardly have to get used to it, the development environment works with a comfortable source code editor and supports the typical Arduino libraries; your own can also be integrated via an import.
the Wiring editor remembers Fritzing and creates easy-to-understand, clear plans; Once created, connections are always automatically re-sorted when components or modules are moved; we just missed an undo function.
