: The path varies by Proteus version and installation:
Double-click the Arduino board in Proteus and paste this path into the field. Troubleshooting Checklist
So here’s the —the one that actually works.
Proteus requires two distinct types of files to simulate any component:
Open your project, click the 'P' button, and search for "MAX30100". The sensor should now appear. 3. Common MAX30100 Proteus Simulation Fixes
📍
The MAX30100 module needs specific connections in Proteus to simulate I2C properly: Connect to 3.3V3.3 cap V (Do not use as it can damage the simulation model). GND: Connect to Common Ground. SCL: Connect to Arduino A5 (I2C Clock). SDA: Connect to Arduino A4 (I2C Data).
Alternatively, if you are looking for alternatives, I can tell you about: The sensor (better performance). Using a Virtual Terminal in Proteus to debug I²C data. The best Arduino code for testing the simulation.
Restart your Proteus software to refresh the component library.
The MAX30100 communicates via the I2C protocol. Because Proteus struggles with floating pins on simulated I2C buses, applying specific hardware fixes within your schematic is mandatory.
What or behavior do you see when starting the simulation?
