You can adjust -// the number of sensors in your project by changing SONAR_NUM and the number of NewPing objects in the -// "sonar" array. You also need to change the pins for each sensor for the NewPing objects. Each sensor -// is pinged at 33ms intervals. So, one cycle of all sensors takes 495ms (33 * 15 = 495ms). The results -// are sent to the "oneSensorCycle" function which currently just displays the distance data. Your project -// would normally process the sensor results in this function (for example, decide if a robot needs to -// turn and call the turn function). Keep in mind this example is event-driven. Your complete sketch needs -// to be written so there's no "delay" commands and the loop() cycles at faster than a 33ms rate. If other -// processes take longer than 33ms, you'll need to increase PING_INTERVAL so it doesn't get behind. -// --------------------------------------------------------------------------- -#include <NewPing.h> - -#define SONAR_NUM 15 // Number of sensors. -#define MAX_DISTANCE 200 // Maximum distance (in cm) to ping. -#define PING_INTERVAL 33 // 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. -unsigned int 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(41, 42, MAX_DISTANCE), // Each sensor's trigger pin, echo pin, and max distance to ping. - NewPing(43, 44, MAX_DISTANCE), - NewPing(45, 20, MAX_DISTANCE), - NewPing(21, 22, MAX_DISTANCE), - NewPing(23, 24, MAX_DISTANCE), - NewPing(25, 26, MAX_DISTANCE), - NewPing(27, 28, MAX_DISTANCE), - NewPing(29, 30, MAX_DISTANCE), - NewPing(31, 32, MAX_DISTANCE), - NewPing(34, 33, MAX_DISTANCE), - NewPing(35, 36, MAX_DISTANCE), - NewPing(37, 38, MAX_DISTANCE), - NewPing(39, 40, MAX_DISTANCE), - NewPing(50, 51, MAX_DISTANCE), - NewPing(52, 53, MAX_DISTANCE) -}; - -void setup() { - Serial.begin(115200); - 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). - } - } - // Other code that *DOESN'T* analyze ping results can 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. - // The following code would be replaced with your code that does something with the ping results. - for (uint8_t i = 0; i < SONAR_NUM; i++) { - Serial.print(i); - Serial.print("="); - Serial.print(cm[i]); - Serial.print("cm "); - } - Serial.println(); -}
