A pulse sensor made with a phototransistor, and a bright LED.
The phototransistor was connected to the SEN input, and its resistance was plotted against time.
A bright light source was aimed at it with a finger placed between the two, such that the light
has to pass through the finger to get to the phototransistor.
The body's pulse causes the opacity
of the finger to change, and this is reflected in the amount of light received by the sensor.
