Hello,
I just purchased the EMG unit and I am having a slight problem. For my project all I need is the the emg to work as a standalone unit. No micro processor of any kind. My connections to the emg pcb is as follows.
I connected my power source to the power connector using the default of 3.3vdc and ground. The power led does come on. I connected my dvm to Analog A0 and the other grnd pin on the power connector. Connected the electrodes to my muscle and ref to my elbow. I did not see a change in voltage. Did I do something wrong in the connection.
I think your multimeter will find it difficult to display anything. Rather connect an oscilloscope to the analog output.
