Tutorial - AD8232 Heart Rate Monitor Hookup Guide
about 5 years ago
I was having the same problem. I did two things.
1) Make sure that your analog in matches the code on the Arduino sketch. If it is hooked up correctly, you then can use a program like coolterm to monitor the serial port and start collecting data. Make sure that you are getting data that makes sense (you can copy then paste the coolterm data into excel and plot, it should look like an EKG).
2) I was using Processing 3 and getting the same error. I downloaded Processing 2.2.1 (https://processing.org/download/?processing) and that seemed to fix the problem
No public wish lists :(
