Using Green LED?? #18

I’d like to use the green LED (also counts) since that is more effective for use on wrists to detect heart beat. How do I use this library or modify it?

Hi, did you solve this problem?

Unfortunately this product is designed for fingertip readings only and consequently it does not utilize the green LED. This is because the Bio-Sensor Hub (MAX32664) is configured with "Firmware Version A" which is configured for IR and RED LED input. However this product uses the MAX30101 which we DO have as a separate product that has its own Arduino Library which allows you to address the green LED specifically.

Good luck!

The product link seems to be broken, would it work with this sparkfun product instead which uses a MAX30101 sensor? In the readme it says the library should work with this, but just wanted to double check.

That's the one!
