Because the MAX32600 mbed board is not compatible with the Bluetooth HC-05, the HC-05 is suitable for Arduino Uno, and the Arduino Uno is smaller and easier to wear. Thus, I focus on plan B in the second semester 2. The microprocessor was changed to Arduino Uno. The aim of this week is testing the MAX30102 optical sensor on the Arduino Uno R3. 

Hardware requirements:

1.     MAX30102 optical sensor

2.     Arduino Uno board

3.     HC-05

Software requirements:

1.     Arduino 1.8-3

2.     The initial code was downloaded from the website (https://github.com/).

Connection requirements:

MAX30102 sensor	Arduino Uno
SDA	SDA
SCL	SCL
INT	10
VIN	3.3V
GND	GND

First of all, the code import in Arduino 1.8-3 platform, adjust the serial port to Arduino Uno and match development board model is Arduino Uno R3. Finally, compile the program, the results can be seen in figure 1.

Figure 1: the results from Arduino.

Conclusion

Bluetooth matching is the highlight of this project, so in order to achieve this function; you can just give up the MAX32600 mbed board and choose the more suitable Arduino Uno board.
