Show HN: Going Contactless with EMG Sensor and Arduino

The armband consists of an EMG sensor, wireless signal transmitter and power source. It will be worn by the user on his arm where we obtain the signals generated by the biceps/triceps. We set a threshold value for the signal. Once the arm proceeds to perform a certain action that will cause the electric signals generated by the muscles to exceed the threshold limit. This will in turn cause the EMG sensor to send a response action function which may be auditory or visually. Finally, the user will be prompted to avoid any involuntary action that might be harmful.
