hello,
I would like to make a circuit that will light an LED or use a speaker to indicate the beats of a heart. The is a circuit I attached taken from the internet and slightly changed so it could flash an LED.
Basically it reflects IR light of the skin and reflects it to the phototransistor
Would this circuit work, light the LED with the beat of a heart?
thanks,
George L.
