Hi everyone,
PLease can anyone take a look on pic and tell me if i'am acquiring ECG signal ??

Hi meth12,
What type of signals are you expecting to see? Do you have any errors or specific issues with your hardware or software? This forum is for assisting with errors/issues you are running into or brainstorming for how to implement something. Can you give more details on what you are trying to do?

Hi ,
well, am excpecting to see EEG signal .... this is a new test can you verify for me please ??
PS: am using 3 electrode, an external amplifier board hooked to to A0,GND and 5V of arduino.

Do you have an oscilloscope to verify that the signal is correct? What kind of amplitudes are you expecting with this signal?

Hi ,
no i dont have an oscilloscope, and i'am expecting to see some picks while blinking my eyes, or while relaxing ...

I am not familiar with EEG/ECG signals but from your last image it looks like your signal is clipping at 5V a little. What is the voltage range you are using on your device?

i have two batteries with 9v. i think it is may be due to pin 5v of arduino ?? what do you think ..?

In order for me to get a better understanding of what is happening could you attach a screenshot of your code?
