She imported the library into Proteus and opened her schematic. The virtual RC522 now sat cleanly connected to her Atmega328P, and the simulator’s console showed sensor responses that matched the datasheet examples. Aria copied her Nano firmware into the simulator and ran it. The first test tag slid across the simulated antenna, and the Proteus virtual module returned the UID—right away, every time. The CRC errors that had haunted her logs were gone. Even advanced features like anti-collision and multi-tag handling behaved as on the bench. For the first time, the gap between prototype and simulation felt bridgeable.
