Hi All,
I am in DESPERATE need of some advice here. I am working on a project for my basic electronics design class. Here is what I need to do...
Design a heartrate counter that
-uses 2 electrodes as the signal source, removes high frequency noise
- counts pulses for 15 seconds every minute
- displays the per minute heart rate for 45 seconds on a three-digit digital display
- reset the count every 60 seconds and restart the counter
So far, I've got a heart rate pulse going into the counter for 15 seconds every minute. For the other 45 seconds of the minute, nothing feeds into the counter. (This was done using filters, a comparator, a
15 second astable multivibrator, 2 bit counter, nor gate, and an and gate)So right now I need to figure out how to:
- reset the counter every 60 seconds
- connect the counter up to a three-digit digital display
I would be SO GREATFUL if someone could help me out with the counter reset and display portion of this-
Thanks! Rachel
