How PinBench simulates it
- An ATmega328P emulation runs the sketch you compiled, with timers, interrupts and
Serial. - Its pins drive the analog circuit solver, so what a pin can do depends on what is wired to it. The 5V and 3.3V pins are supplies there too, so a divider or sensor powered from them reads what it would on a desk.
- I²C runs on A4 (SDA) and A5 (SCL), as on the real board.
