How It Works

The Smart Inclinometer & Multi-Purpose Measurement Device operates as an integrated embedded system built around the Arduino Pro Micro microcontroller. At its core, the device coordinates multiple sensor inputs and visual outputs primarily through the I2C communication protocol. The MPU6050 sensor combines a 3-axis gyroscope and a 3-axis accelerometer, allowing the microcontroller to calculate precise spatial orientation, tilt angles, and acceleration data in real-time. This spatial data can be processed to emulate an inclinometer, compass, or protractor. Additionally, the MAX30100 sensor utilizes pulse oximetry and heart-rate monitoring technology via optical sensors to capture biometric data. Once the Arduino Pro Micro processes the raw data streams from both the inertial measurement unit and the biometric sensor, it formats the output information and renders it onto a compact SSD1306 OLED display. Power is supplied reliably via a compatible 3.3V to 5V battery setup, ensuring the entire assembly remains portable while maintaining the correct logic and operational voltage levels required by the sensitive integrated circuits.

Why Build This

Frequently Asked Questions

Can I use an Arduino Uno instead of the Arduino Pro Micro?

While the project data specifies the Arduino Pro Micro for its compact form factor, an Arduino Uno shares the same core ATmega architecture and can be used for prototyping, though the physical assembly will be much larger and less portable.

Why is proper voltage regulation important for this circuit?

Components like the MAX30100 sensor and the SSD1306 OLED display are sensitive to overvoltage conditions; ensuring a stable 3.3V to 5V supply prevents permanent hardware damage.

How do multiple I2C sensors connect to the microcontroller simultaneously?

The MPU6050, MAX30100, and SSD1306 all share the same I2C data (SDA) and clock (SCL) lines, relying on unique hardware addresses built into each sensor chip to communicate independently with the Arduino.
