I have followed the instructions on DEF robots website for uploading the code for the bluno beetle and the EMG sensor from oy motion. I have uploaded the code into a new sketch in the IDE and uploaded it to the board and I get no results. When I try to verify the sketch it says emgfilters.h is not included. Can someone please help put the code in the right order for me. I am trying to have the emg sensor show a display on a waveform what the voltage is.
The emg code is below
