1. Provide Power Connections:
   • Connect 3V3:P1 to ATmega328P:VCC (Pin 7 for power) to supply the MPU-6050 with 3.3V.
   • Connect GND to ATmega328P:GND (Pin 8 or 22 for ground).
2. Connect the I2C Lines:
   • Connect SCL:P1 (Serial Clock) to ATmega328P:PC5 (Pin 28, SCL for I2C communication).
   • Connect SDA:P1 (Serial Data) to ATmega328P:PC4 (Pin 27, SDA for I2C communication).
3. Setup Pull-up Resistors for I2C Lines:
   • The MPU-6050 reference design should already include pull-up resistors for the SCL and SDA lines (R1 and R2). Ensure they are correctly connected to ensure stable I2C communication.
4. Additional Connections:
   • If you intend to use the interrupt feature of the MPU-6050, INT:P1 should be connected to an appropriate external interrupt pin on the ATmega328P, like PD2 (Pin 4, INT0).

• Gather Components: Ensure you have the MPU-6050 module, an ATmega microcontroller (e.g., ATmega328P), a breadboard, jumper wires, pull-up resistors (if not using Arduino which has built-in), and a power source.
• Circuit Connections:
  • Connect the MPU-6050's VCC to the ATmega328P's 3.3V output to power the sensor. If your ATmega system operates at 5V, use a voltage regulator to provide 3.3V to the MPU-6050.
  • Connect the GND of the MPU-6050 to the GND of the ATmega328P.
  • Connect SDA and SCL of the MPU-6050 to the ATmega328P's SDA (PC4) and SCL (PC5) pins, respectively.
  • Attach pull-up resistors (e.g., 4.7kΩ) between SDA, SCL lines, and the 3.3V power line if they're not already implemented in your system.
  • If using MPU-6050's interrupt features, connect the INT pin to one of the external interrupt pins on the ATmega (e.g., PD2 for INT0).

• Set up Development Environment: Install the necessary software for coding and uploading firmware to your ATmega chip. This could be the Arduino IDE if you're using an Arduino bootloader or AVR-GCC for raw C programming.
• Code Writing:
  • Initialize I2C communication in your microcontroller's firmware.
  • Write functions to read from and write to the MPU-6050's registers.
  • Implement algorithms to interpret the accelerometer and gyroscope data, such as converting raw data to understandable units (e.g., g's for acceleration, degrees per second for rotation).
• Library Usage: Optionally, for Arduino, leverage existing libraries like "Wire.h" for I2C communication and "MPU6050.h" (if available) to simplify interactions with the sensor.

• Initial Test: Upload the firmware to the ATmega and power up the circuit. Check for basic signs of life (LEDs, serial output).
• Functionality Test: Run a simple program that outputs MPU-6050 data to a serial monitor. Observe if the accelerometer and gyroscope readings change with the sensor's orientation and movement.
• Debugging: If the data does not appear or seems incorrect, double-check your connections, review your code for logical errors, and ensure correct I2C addresses and register values are used.
• Iterate: Modify your firmware and hardware setup based on test results until your project meets the desired functional requirements.

• Circuit Board Design: Once satisfied with the breadboard prototype, design a PCB to create a more robust and permanent version of your project.
• Software Optimization: Optimize your code for efficiency, memory usage, and reliability. Include additional features or user interfaces as needed.
• Documentation: Document your project design, code, and usage instructions for future reference or to share with others.

1. ATmega Microcontroller:
   • Search for "ATmega328P" in the component library. If this specific model isn't available, look for an equivalent ATmega microcontroller that meets your project's needs.
   • Add the microcontroller to your schematic.
2. Power Supply:
   • You will need a 3.3V power supply for the MPU-6050. If your ATmega microcontroller operates at 5V and you don't have a direct 3.3V supply, search for a "3.3V regulator" component and add it to your schematic for voltage regulation.
3. Pull-up Resistors for I2C:
   • Typically, 4.7kΩ resistors are used as pull-up resistors on the SDA and SCL lines for I2C communication. Add two resistors with a value of 4.7kΩ (you might find it as "4.7k ohm resistor") to your schematic.
4. Connections to ATmega:
   • Since we are considering an ATmega328P (or a similar pinout microcontroller), you'll find the I2C pins labeled as SDA (PC4) and SCL (PC5). These would be connected to the respective SDA and SCL pins of the MPU-6050.
   • Don't forget to connect VCC (to 3.3V), GND, and if you're using interrupts, the external interrupt pin on the ATmega to the MPU-6050's INT pin.
5. Additional Components:
   • For more complete circuitry, consider adding decoupling capacitors near the power supply pins of both the MPU-6050 and the ATmega microcontroller. A value like 0.1μF is commonly used for this purpose. Add two 0.1μF capacitors to your schematic.

• Open your project in Flux.ai.
• On the left pane, you'll find a component library. Use the search bar to find each component I mentioned above.
• Click on a component to select it, and then click again on your schematic where you want to place it.
• Wire the components together by dragging from pin to pin. This includes all power, ground, and signal connections I outlined.
• Utilize the properties panel to adjust component values as necessary, like changing resistor values to 4.7kΩ.
