I'm new to Arduino. I do not know how to program. I need help (a lot) to make the Arduino send a bar graph of the IBI (in reality, the inverse, BPM) to a 2x16 LCD in real time. The goal is to get biofeedback from the device and increase one's HRV.
Up to now I have been able to obtain the graph that they show in pulsesensor.com, both in IDE and Processing. I just want to go further.
