title: ECG processing using arduino
body: <p>We are doing a project on ECG signal extraction.We got the extraction and it is full of noise(50 hz) so we need to process the signal and we are proposed to process it via arduino board.we need to denoise it by using arduino.</p>
  
  <p>How can we do ECG processing using arduino board and which arduino board is perfectly suitable with less cost and more accuracy and that arduino should be small?</p>
