Electroencephalograph Recording with Ten-Twenty Electrode System Based on Arduino Mega 2560

Improved Technology until now started to help many aspects of human works, including medical facilities. One of them is Electroencephalography (EEG) which records electrical activities of the brain. This technology is used to diagnose any brain disease that makes an abnormality at EEG signal recording. EEG usually has non-invasive methods, where electrodes placed on the scalp that easy and reusable. This technology itself has been started in 1924 by Hans Berger. This paper discusses the basic construction of EEG, focused on simulation, device construction, and results from devices. It will further mention how Arduino Mega 2560 record analog signals, circuit diagrams that will be used, and final results that showed and processed on SCILAB application. The final result would use Ten-Twenty Electrode System which can be compared with any result from any different recording and be displayed in SCILAB with graph form that has been filtered with Fast Fourier Transform (FFT) results.
