This is the biggest drawback.
Press the Play button. The LED should blink every second.
Tip: For serial, ensure Virtual Terminal’s baud rate matches your code (115200). Right-click Virtual Terminal → Edit Properties.
| Works ✅ | Won’t Simulate ❌ | |-----------------------------------|----------------------------------| | GPIO, digitalWrite, pinMode | Wi-Fi, Bluetooth | | Serial (UART) | Deep sleep current draw | | delay(), millis() | Real-time ADC accuracy | | Simple I2C/SPI (basic) | Interrupts might be buggy |
💡 Use Proteus ESP32 simulation for logic testing and teaching. For final RF or power-sensitive projects, test on real hardware.
The Proteus ESP32 library is a stopgap, not a replacement. It is excellent for validating the logic of your code and the layout of your circuit, but it fails to simulate the very thing that makes the ESP32 special: its connectivity.
Recommendation: Use Proteus to get your circuit design right and debug basic logic. Once the code logic works in Proteus, move to real hardware immediately to handle the Wi-Fi and timing aspects. esp32 library proteus
For schematic drawing: Yes. It allows you to create professional PCB layouts with an ESP32 symbol.
For code simulation: No, unless you are only toggling a few LEDs or buttons.
For IoT projects: Absolutely not. You cannot simulate Wi-Fi, MQTT, or HTTP requests.
The best practice today is to use Proteus for circuit design (power supply, sensors, connectors) and then test your ESP32 code on real hardware or use Wokwi for quick logic validation. As Labcenter continues to develop their ESP32 model, we may see full support in Proteus 9 or 10, but until then, manage your expectations.

To simulate an ESP32 in Proteus, you need to manually add external library files, as the board is not typically included in the default installation Installation Steps Download the Library
: Obtain the library ZIP file from trusted community sources like The Engineering Projects Extract the Files : Unzip the folder to find two essential files: Locate the Proteus Library Folder Common path This is the biggest drawback
C:\Program Files (x86)\Labcenter Electronics\Proteus 8 Professional\LIBRARY Alternative path
C:\ProgramData\Labcenter Electronics\Proteus 8 Professional\LIBRARY
Note: If "ProgramData" is hidden, enable "Hidden items" in Windows Explorer view settings. Paste and Restart : Copy the files into the Proteus folder. If Proteus was open, you must restart it to load the new components. Find the Component : In Proteus Schematic Capture, press to open the component picker and search for How to Run Simulation Code
To execute code on the simulated ESP32, you must link it to a compiled Compile Code
: In the Arduino IDE, verify/compile your code for the "ESP32 Dev Module". Load the File : Double-click the ESP32 component in Proteus, and in the "Program File"
field, browse for and select the compiled file from your computer's temporary build folder.
: Click the play button in the bottom-left corner to start the simulation. or help finding the compiled hex file path in the Arduino IDE? ESP32 Proteus 8 - Simple Embedded electronics projects Tip: For serial, ensure Virtual Terminal’s baud rate
While Proteus does not natively include an ESP32 model, you can add it by installing third-party library files. This allows you to create circuit diagrams, design PCBs, and simulate basic I/O logic, though specialized features like Wi-Fi and Bluetooth cannot be simulated within the software. How to Add the ESP32 Library to Proteus
To get the ESP32 module appearing in your component list, follow these steps: Download the Library Files : You will need a
file specifically for the ESP32. Reliable community sources include The Engineering Projects Locate the Proteus Library Folder Navigate to your Proteus installation directory. Common path:
C:\Program Files (x86)\Labcenter Electronics\Proteus 8 Professional\DATA\LIBRARY
Note: If you cannot see the "ProgramData" folder, enable "Hidden items" in your File Explorer view settings. Install the Files : Copy and paste both the files into that Verify in Proteus : Restart Proteus, open "Schematic Capture," press
to pick devices, and search for "ESP32." You should now see the module available for placement. Simulation & Limitations How to Add the ESP32 Library to Proteus 8
