I really love Qt, so one of the first things I wanted to do is to get my Qt application running on raspberry Pi.

Thank you !
Thank you for the fast feedback i uplouded the code, but i have some problems
So in the link bellow i have two pictures, the upper is when i have my finger on it and the second is when the sensor dont have anythink on...
I'm not sure if I updated the code in the article. But there was one glitch regarding pulse width and LED current. And the waveform more or less looked like the one you have screenshotted.
It has been fixed on the github:...
Great explanation and work on the heart beat monitor sensor,
