Mode on Filtering Techniques Explored: Low-pass filter: A lowpass filter is one which attenuates the high frequency components of a spectrum while ‘passing’ the low frequencies within a specified ...

Just when you thought you’d seen an Arduino do everything, [birdyberth] built an Arduino powered Electrocardiogram (ECG or EKG). Electrocardiography is a non invasive method of studying the heart. For ...

We used ECG sensor which is self-made. Depending on Arduino input voltage (0V ~ 5V) -> End of the sensor circuit, there is a inverting amplifier which changes the range of output voltage of sensor.
