First we connected the EKG-EMG-Shield to an Arduino UNO R3 uploading a modified version of the example code. Afterwards we fixed two of the cables at Tobias’ wrists, the odd one at his ankle. Established serial data-stream to Processing and coded a simple graphical representation. This is what we got so far.
Of course we lack the beautiful shape of the classic ECG Curve. Actually we got shiploads of noise here due to dry skin contact. But somewhere down in this dotty forest apparently we find a repetitive pattern. And we are pretty sure that its interval appears synchronous to Tobias’ pulse.
