SUMMARY

The discussion centers on finding a heart beat detector circuit that utilizes an LED display to show heart rate in a column format. Benzun suggests using a soundcard as an Analog-to-Digital Converter (A/D), referencing a specific resource that provides relevant information on ECG circuits. The provided link leads to a University of Utah project that aligns closely with the user's requirements for a standalone heart beat detection solution.

PREREQUISITES
  • Understanding of basic electronic components and circuits
  • Familiarity with Analog-to-Digital Conversion (A/D) techniques
  • Knowledge of LED display interfacing
  • Basic principles of electrocardiography (ECG)
NEXT STEPS
  • Research the implementation of soundcards as A/D converters for biomedical applications
  • Explore the design and construction of LED display circuits for real-time data visualization
  • Investigate existing ECG circuit designs and their components
  • Learn about signal isolation techniques in biomedical devices
USEFUL FOR

Electronics enthusiasts, biomedical engineers, and hobbyists interested in building heart rate monitoring devices and understanding ECG technology.

can anyone sugest me a good heart beat detector circuit. note the circuit must detect the current from the heart and LED display in a column.

I'd found this in a search to use the soundcard as an A/D and is pretty close to being right in the ballpark of your question. And since you're not connecting to a computer the isolation isn't a major issue.
