The GY-521 breakout exposes four pins:

Pro tip: Add two 4.7k pull-up resistors on SCL and SDA lines to 3.3V in the schematic – this mimics real hardware.

The true power of the UPD library lies in automation. You can drive the simulation using a Debug Stimulus file or external script. For example:

This allows you to test a Kalman filter or PID controller for a self-balancing robot without any hardware.

The objective is to simulate the GY-521 MPU6050 module using the Proteus ISIS software and demonstrate its use in a simple project.

If you already have an older MPU6050 model for Proteus 7/8, an “update” might involve:

As of Proteus 8.x / 9.x (latest official releases):

Follow this step-by-step guide to integrate the library. Note: Ensure you have administrator rights and a legitimate copy of Proteus (8.9 or higher recommended).
