3. THE SYSTEM
Smart stopwatch for recording athletic training
3

4. Problem
For athletes at competitive level it's hard to
record the time of their training sessions in an
easy way, especially when they're alone.
4

5. Solution
Digital system to record automatically athletic
training time using Android interface.

6. Why Chronosmart?
Chronosmart is born from a real demand of
CONI association in Latina:
▷ Help athletes training alone, without
losing the precision of results monitoring.
▷ Not carry bulky, wired recording tools.
▷ Keep track of past results.

8. How it works
Last
Microcontroller sends
the time recorded to the
Android app, which
manages the data
received and store them
to the db, after user’s
confirmation.
First
Position the proximity
sensors in the starting
and ending points of the
track.
Second
Athlete runs, the system
records, automatically
detecting departure and
arrival.

10. 10
Nucleo F401RE + Arduino IDE

11. Initialization
11
#include <f401reMap.h> // Nucleo board mapping for
Arduino IDE
[...]
[...]
// Proximity sensor initialization
pinMode(triggerPort, OUTPUT);
pinMode(echoPort, INPUT);
[...]
[...]
// Proximity sensor in action (monitoring)
digitalWrite( triggerPort, LOW );
digitalWrite( triggerPort, HIGH );
delayMicroseconds( 10 );
digitalWrite( triggerPort, LOW );
long RTT = pulseIn(echoPort, HIGH ); // Round Trip Time
detected by the sensor
[...]

12. Starting point
When the runner starts the sensors detects no
more and the chronometer is initialized.
12

13. Timing
13
[...]
// Chronometer in action
baseTime = millis();
[...]
[...]
// Proximity sensor in action (monitoring)
digitalWrite( triggerPort, LOW );
digitalWrite( triggerPort, HIGH );
delayMicroseconds( 10 );
digitalWrite( triggerPort, LOW );
long RTT = pulseIn(echoPort, HIGH ); // Round Trip Time
detected by the sensor
[...]

14. Ending point
When the runner arrives at the goal line the
sensors detects and the chronometer is stopped.
14
finalTime = millis();
computedTime = finalTime - baseTime;
computedTimeSec = computedTime/1000;
