  Hai,
  
  Iam doing a project on Heart beat monitor.Nothing much just a project that produces sound in a speaker from the heart beat pulse..The project is without microcontrolelrs
  
  But i wish to moddiify the project by also adding a additional counter along eith it.i.e a counter to count the no of heart beats per minute[it shud store and show values beat in a minute not more than tht]and display it in a seven segment display.
  
  Can you tell me what i am supposed to do?
  
  thanks in advance

  Can you please let me know that which sensor you are using to detect Heart Beat? Once you get pulses from that sensor then its easy to process and count the beats.

  As per my knowledge i think you can take the signal from Capacitor C8.
  and from there add the counter circuitry and for pulses in a minute i have to search. Can we use 555 Timer? try to get information on that.

  Actually i am think it becomes easy if we use Controller as just connect that pulse to interrupt pin and that makes easy to count the pulses in one minute. I am searching for other way. you too try to get some data on this.
