how to control videos from 3 ultrasonic sensors from arduino

edited August 2015 in Arduino

HI ! I'm working with 4 ultrasonic sensor, that plays 2 videos and 2 sounds, the problem is that at some point the computer restart the videos, and sounds. I can`t figure out where is the problem, i already chek the sensor and they work find, so, mabye is a problem of comunication betwen arduino and processing? mabye arduino reset?

anyIdeas? help! the openinng of this art instaattion is this friday!

    #include <NewPing.h>
    #define SONAR_NUM     4 // Number or sensors.
    #define MAX_DISTANCE 200 // Maximum distance (in cm) to ping.
    #define PING_INTERVAL 633 // Milliseconds between sensor pings (29ms is about the min to avoid cross-sensor echo).
    unsigned long pingTimer[SONAR_NUM]; // Holds the times when the next ping should happen for each sensor.
    byte cm[SONAR_NUM];         // Where the ping distances are stored.
    uint8_t currentSensor = 0;          // Keeps track of which sensor is active.
    NewPing sonar[SONAR_NUM] = {     // Sensor object array.
      NewPing(11, 12, MAX_DISTANCE), // Each sensor's trigger pin, echo pin, and max distance to ping.
      NewPing(10, 9, MAX_DISTANCE),
      NewPing(8, 7, MAX_DISTANCE),
      NewPing(14, 15, MAX_DISTANCE)

    };
    void setup() {
      Serial.begin(9600);
      pingTimer[0] = millis() + 75;           // First ping starts at 75ms, gives time for the Arduino to chill before starting.
      for (uint8_t i = 1; i < SONAR_NUM; i++) // Set the starting time for each sensor.
        pingTimer[i] = pingTimer[i - 1] + PING_INTERVAL;
    }
    void loop() {
      for (uint8_t i = 0; i < SONAR_NUM; i++) { // Loop through all the sensors.
        if (millis() >= pingTimer[i]) {         // Is it this sensor's time to ping?
          pingTimer[i] += PING_INTERVAL * SONAR_NUM;  // Set next time this sensor will be pinged.
          if (i == 0 && currentSensor == SONAR_NUM - 1) oneSensorCycle(); // Sensor ping cycle complete, do something with the results.
          sonar[currentSensor].timer_stop();          // Make sure previous timer is canceled before starting a new ping (insurance).
          currentSensor = i;                          // Sensor being accessed.
          cm[currentSensor] = 0;                      // Make distance zero in case there's no ping echo for this sensor.
          sonar[currentSensor].ping_timer(echoCheck); // Do the ping (processing continues, interrupt will call echoCheck to look for echo).
        }
      }
      // The rest of your code would go here.
    }
    void echoCheck() { // If ping received, set the sensor distance to array.
      if (sonar[currentSensor].check_timer())
        cm[currentSensor] = sonar[currentSensor].ping_result / US_ROUNDTRIP_CM;
    }
     void oneSensorCycle() { // Sensor ping cycle complete, do something with the results.
        Serial.write(cm, SONAR_NUM);
    };

    I think first you have to train with the processing examples that are examples of Arduino...Arduino-->file-->example-->communication--> graph (or another)

  • ChrisirChrisir

    use

    if(1st sensor on}

    else if (2nd sensor on)

    else if (3rd sensor on)

    show your code

    ;-)

    It's good idea chrisir! so I guest the right question will be, How do I declare the 3 sensor from arduino in processing?

  • ChrisirChrisir

    look at the examples please

    Well i get close troghout a code , but now i have the problem that i cant get two sensors activate a video, and one just a sound, looks like the check is too fast and oscilates all the time and start over, any ideas?

    You'll get a better response if you format your code. Here's how:
