This is a demo of heartbeat detection from hand EKG with the help of BioAmp EXG Pill, Arduino Nano, and HeartBeatDetection.ino code.

This is a demo of heartbeat detection from chest ECG with the help of BioAmp EXG Pill, Arduino Nano, and HeartBeatDetection.ino code.

Arduino sketch for controlling a servo motor with EMG has been added.

Arduino sketch to show EMG potential on an LED Bar graph has been added.

An envelope detector is a sophisticated algorithm that takes a (relatively) high-frequency amplitude modulated signal as input and provides an output, which is the demodulated envelope of the original signal. To use the EMG signal sampled by the ADC in a useful manner we need to detect an envelope of the signal recorded. A standalone Arduino code EMGEnvelop.ino has been added to the EXG repository which can be used for things like an LED bar graph of EMG potential and Servo control.

A development-board independent EMG Filter Arduino code has been added to the BioAmp EXG Pill Github repository. The frequency response plot of the band-pass filter implemented and image of recorded EMG is attached below.

Different BioPotential signals (ECG, EMG, EOG, and EEG) contain information in different frequency bands and require a minimum sampling rate to not lose any valuable data.

FixedSampling Arduino code allows you to set a fixed sampling rate for your Arduino-compatible board's ADC input. Fixed sampling also helps in applying digital filters onto the signal recorded as you are required to have a fixed sampling rate for that.
