My explorations with the heart pulse sensor lead me to creating a low-fidelity prototype of e-cards!
I wanted to explore data transferring between both the Arduino IDE software and Processing using the pulse sensor. The idea of using pulse sensory data to create an intimate and personal interaction sparked my interest in how I could create this sweet savoury like project/prototype.
I sketched out what I wanted to do step by step on paper. First, I was going to setup and play around with the pulse sensor in Arduino to see how it worked and how the examples provided in the playground sensor library was tracking my heart rate. I followed the instructions from the pulse sensor’s website to help me set up.
I was able to successfully set up the pulse sensor and started playing around with the example sketches in the Arduino IDE.
This setup and serial data is from the PulseSensor_BPM code in the pulse playground library. I made a new file called Heart Beat and added the syntax line “Serial.write(myBPM)” to send the data over to processing.
I then sent this data over to a processing sketch, opened the port and placed the incoming data in an ellipse’s properties to manipulate its shape.
I later applied this manipulation to an image:
My incoming BPM would cause the image to appear on the screen every time the sensor read my heart beat. I later had some fun and thought this would be a cute valentine e-card.
For future works I’d like to take this sort of concept online so long distant lovers could send over in-real time e-cards of their partner’s heart beats. This could also be implemented in webcam calls or on common online canvases.
