Shield EKG-EMG Arduino

[Jose Aparecido]

I think I was putting the question in the wrong place at the site,
please check if you can help me ...

I'm trying some tests with EKG-EMG Shield for Arduino Uno, I bought the product and model you find on this link:
https://www.olimex.com/Products/Duino/Shields/SHIELD-EKG-EMG/

I put the electrodes as follows:
L on the left arm - wrist
R and D on right arm - the arm and forearm

I did do some testing with Shield EKG / EMG, but I think the system is configured for ECG, because the signal is showing "peaks" from time to time, Estou usando ElecGuru to monitor the signal.

The question is: Change something in the Shield (jampers) configuration to use as EMG?

I would like some advice, if you have any documentation that better detail the operation of the Shield ( and Electrodes), in addition to the user manual available?

As I said before I'm sorry, my English is not very good ...

Thank you in advance for any help,

thank you

I also have the same problem.

I really appreciate any help you can provide.

Hey guys,

You don't have to change anything hardware wise to switch between EKG and EMG mode.

The only thing that might require switching is the analog channel but you have to change it in the code too.

However, the code itself is much more complex and depends on the specific muscles (muscle group) you are targeting. Additionally, because of the placement of the electrodes, most of the muscles can't be recognized with just one channel (you would need at least two shields stacked).

Please check this customer project that demonstrates the EMG possibilities of the board:

About the UNO please check the following posts, note that the Arduino example available at the web page should work:
