Circuit Documentation

Summary

The circuit in question is designed to interface various sensors and modules with an Arduino UNO microcontroller. The sensors and modules include an MPU6050 accelerometer and gyroscope, a GPS NEO 6M module, a MAX30100 pulse oximeter, an HC-05 Bluetooth module, and a PH Meter. The Arduino UNO serves as the central processing unit, collecting data from the sensors, processing it, and communicating with external devices via Bluetooth. The circuit is powered by a 5V supply, which is distributed to all components that require power.

Documented Code

Arduino UNO Code (sketch.ino)

void setup() {
  // put your setup code here, to run once:

}

void loop() {
  // put your main code here, to run repeatedly:

}

Note: The provided code is a template and does not include any functionality. It needs to be populated with the setup and loop code to initialize the components and handle the data acquisition and communication.

Additional Notes

• The MAX30100 scl and sda pins are not connected according to the net list provided. These should be connected to the Arduino's I2C pins if communication with the sensor is required.
• The documentation.txt file is empty and thus not included in this document.
