Open the Arduino IDE. Install the standard and I2Cdev libraries via the Library Manager. Write a basic script to initialize the sensor and stream raw accelerometer (X, Y, Z) and gyroscope values to the serial port. Go to File > Preferences in the Arduino IDE and check the compilation warning box for "show verbose output". Click Verify/Compile . Locate the compiled .hex file path in the console window at the bottom of the screen. 3. Load the Hex File into Proteus
Confirm the device address matches your code. The standard address is 0x68 , but if the AD0 pin is held high in your simulation model, the address changes to 0x69 . Simulation runs too slowly: High-frequency I2Ccap I squared cap C Mpu6050 Proteus Library
The simulation model in Proteus mirrors the physical pinout of the chip.
#include // MPU6050 I2C address (0x68 is default when AD0 pin is LOW) const int MPU_addr = 0x68; int16_t AcX, AcY, AcZ, Tmp, GyX, GyY, GyZ; void setup() Wire.begin(); Wire.beginTransmission(MPU_addr); Wire.write(0x6B); // PWR_MGMT_1 register Wire.write(0); // Set to zero to wake up the MPU-6050 Wire.endTransmission(true); Serial.begin(9600); void loop() GyroX: "); Serial.print(GyX); Serial.print(" Use code with caution.

Place an block and the MPU6050 block into your Proteus workspace. Connect SCL to analog pin A5 and SDA to analog pin A4. Add pull-up resistors (typically 4.7kΩ) to both the SCL and SDA lines, connecting them to the +5V source to ensure clean I2C signal transmission. Finally, place a Virtual Terminal tool from the instruments menu and wire its RX pin to the Arduino's TX pin (Pin 1) to view numeric outputs. 2. Write and Compile the Firmware Go to File > Preferences in the Arduino

Proteus includes basic sensors (e.g., LM35 temperature sensor, LDR) but lacks advanced MEMS sensors like the MPU6050. Without a library, you cannot:
