Hello comunity of Arduino-

One question: where can download one simulator/emulator breadboard for micro contoller Ardiuino leonardo?

Hola comunidad de Arduino-

Una pregunta: ¿donde puedo descargar un simulador/emulador de breadboard/protoboard que funcione para micro controlador Leonado?

In general with microcontrollers (as arguably with PCs), it makes far more sense to build-and-test step by step in a modular fashion, using the Serial Monitor to issue diagnostics.

In other words, you use the software itself as the debugger and the hardware as your emulator. This is particularly true as time-critical sections are likely to use hardware that you cannot emulate anyway (such as of course, the USB interface).
