??Counting pulses
The multi-function shield library has support for counting pulses (up to 500Hz) applied to an input pin of the Arduino. The counting of pulses is managed in the background using interrupts, which allows your application to focus on performing its main task. After uploading this sketch, repeatedly press button 1 to generate the pulses and see a reading of the press rate on the digit display.

/* This application requires a heart beat sensor similar to the one shown in the image below, which uses infrared light to detect pulses in a finger or ear lobe. When normalized, the sensor outputs an analogue signal of 2.5 volts, which rises and drops every time the blood flow changes due to a heart beat. The application works by counting every time the signal rises above 3 volts, then drops below 2.5 volts, and measures time between pulses to calculate the beats per minute. The beeper is sounded every time a heart beat is detected. The sensor output will need to be connected to Arduino pin A5 exposed on the multi-function shield.After powering on the Arduino, gently but firmly place the index finger on the sensor and wait for the display to start blinking. This indicates the sensor has normalized, after which the shield display will show the beats per minute, and the beeper will sound. If the display remains at 0 and doesn’t blink after several seconds, remove the finger, wait for a while and try again. Ensure the finger is placed with consistent pressure.Possible modification for this application is to have an LED light synchronised with each heart beat.*/
