same as last but with working calibration (fully flex muscle for 2 seconds and press button)

signal filter working, included calibration function. which sets a value by taking average over some time and dividing by a counter. The light blinks if the measured value is above the calibartion value.

two filters with two rectifiers. Works pretty good;

Two filters (variable Fc) and rectifier. EMG looks doable. Light wil turn on above a certain value (worked one time, but not after then);

double filter (many types possible). Sending three signals to HIDscope (original, one filter, two filter);

low-pass (fc = 5hz) and high pass (fc = 1 hz) filter in cascade working. Using A0 to read signal and sending to HIDscopen;

Working low-pass filter. only one filter in place. Takes A0 as input and sends a filterd signal to HIDscope; ;

Testing filters with one wire (DAC0_OUT) is output and (A0) is input. 21 september;
