Arduino Breathing Monitor

The video tutorial introduces an Arduino-based breathing monitor that uses conductive rubber sensors to measure chest and belly breathing. It demonstrates how different breathing patterns light up LEDs, with shallow chest breaths lighting green LEDs and deeper belly breaths lighting blue LEDs. The video concludes with the benefits of belly breathing, such as reduced blood pressure and improved relaxation, as noted by the Cleveland Clinic.

What materials are mentioned as being used to create the sensors for the breathing monitor?

How do the LEDs indicate the type of breathing being performed?
