Wire the Arduino Uno and MAX30100 as shown above.
Note: ProgramData is a hidden folder. You may need to enable "Show hidden files" in Windows. Paste the files into this folder.
.LIB and .IDX files are placed inside the correct path ( DATA\LIBRARY or ProgramData ). Proteus was restarted after the library paste. max30100 proteus library download fix
Even with the library installed, simulation often fails, typically showing an I2C failure or an "initializing pulse oximeter failed" error in the virtual terminal. Fix 1: Properly Configure I2C Pins (Pull-up Resistors) operates on I2Ccap I squared cap C
Proteus does not automatically detect files in the "Downloads" folder. You must manually move them: [ Arduino Uno ] [ Pull-Up Resistors ]
Copy the downloaded MAX30100Library.LIB and MAX30100Library.IDX files.
How to Fix MAX30100 Proteus Library Download and Simulation Errors You may need to enable "Show hidden files" in Windows
There is no official, fully functional MAX30100 simulation model for Proteus (as of 2025–2026). Proteus lacks an I2C optical sensor model that mimics real-time PPG signals.
The Virtual Terminal should now display simulated heart rate (BPM) and SpO2 percentages without throwing any simulation log errors.
