UPDATE- Week 5

Posted by : x Friday, May 2, 2014


We are currently working on connecting all the parts of the ECG to breadboard. The circuit has been fully connected and we are seeing good results with signals. The custom designed ECG needed a lot of fine tuning with Op-Amp amplification and filtering techniques. This website http://www.kevindarrah.com/ was a big help. We also looked into other algorithms and one by http://pulsesensor.com/ works well. Combining these we were able get stable signals. Processing 2 was used to program a serial port listener which recieved data from the designed sensor and displayed a moving graph.
