SparkFun Bio Sensor Arduino Library
If you're using the RedBoard Qwiic and have never connected a CH340 device to your computer before, you may need to install drivers for the USB-to-serial converter. Check out our section on How to Install CH340 Drivers for help with the installation
We've written an Arduino library to make it even easier to get started with the SparkFun Pulse Oximeter and Heart Rate Monitor. The library will give you the full functionality of the sensor and provides example code to get the most our of your project. You can obtain these libraries through the Arduino Library Manager by searching SparkFun Bio Sensor Arduino Library. The second option is to download the ZIP file below from its GitHub repository to manually install it.
