The ESP32 library for Proteus is an essential third-party add-on that allows engineers and hobbyists to simulate IoT designs before building physical hardware. While Proteus does not include ESP32 in its native library, manual installation enables the simulation of GPIO, UART, I2C, and SPI peripherals. Key Features of the ESP32 Proteus Library

Download the Library: Obtain the library files (typically .LIB and .IDX) from sources like The Engineering Projects or GitHub.

• ESP32.IDX
• ESP32.LIB

#include <WiFi.h>
3. PlatformIO with Sloeber (Debugging only)

Not a schematic simulator but allows step-by-step code debugging.
No virtual circuit.
