Introduction
For this module, you will design, build, program, and test a microcontroller-based photoelectric
heart rate monitor. This kind of heart monitor is attached to a patient finger to measure the heart
rate in beats per minute (BPM). The device you will be building is based on a non-invasive
photo transmitter/receiver pair sensor which detects small variations of blood flow in the
fingers due to the heart pumping action. After filtering and amplifying such variations, a
microcontroller-useable signal can be generated. By measuring the period or frequency
of such signal, the heart rate of the person using the sensor can be determined. There is
some information about these types of sensors in the internet. A good article with a
single power supply amplifier/filter can be found at:

You can use that article as reference for your own design.
## Deliverables
