The selfmade sensor with the IR Emitter and Detector is very sensitive for any motion and movements of the finger being measured. So I tried out a EKG Sensor which displayed a higher resolution of the heartbeat on processing. There are 3 electrodes patches placed on the skin: One on the right wrist for the reference, one on right elbow for the negative alligator clip and one on the left elbow for the positive clip. | The selfmade sensor with the IR Emitter and Detector is very sensitive for any motion and movements of the finger being measured.

The EKG Sensor is connected with the Arduino to Ground, 5V and Analog Input A0. The heartbeat is displayed with Processing. | ||
