Error when combining two simple sketches - range sensors and photocells

Projects Programming

Here is what I've been attempting. It will read both the range sensors and the photocells, but I get 5 readouts of photocells for every one read of range sensors.

Here's the code

#include <NewPing.h>

#define SONAR_NUM     6 // Number or sensors.
#define MAX_DISTANCE 200 // Maximum distance (in cm) to ping.
#define PING_INTERVAL 20 // 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(2, 3, MAX_DISTANCE), // Each sensor's trigger pin, echo pin, and max distance to ping.
  NewPing(4, 5, MAX_DISTANCE),
  NewPing(6, 7, MAX_DISTANCE),
  NewPing(8, 9, MAX_DISTANCE),
  NewPing(10, 11, MAX_DISTANCE),
  NewPing(12, 13, 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).
    }
  }
  
 //Photocells
 
int p1read = analogRead (A0);
int p2read = analogRead (A1);
int p3read = analogRead (A2);
int p4read = analogRead (A3);
int p5read = analogRead (A4);
int p6read = analogRead (A5);
   
Serial.print ("photo ");
Serial.print (p1read);
Serial.write(32);
Serial.print (p2read);
Serial.write(32);
Serial.print (p3read);
Serial.write(32);
Serial.print (p4read);
Serial.write(32);
Serial.print (p5read);
Serial.write(32);
Serial.print (p6read);
Serial.println("");
delay (20);
}


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.
  for (uint8_t i = 0; i < SONAR_NUM; i++) {
    Serial.print(i);
    Serial.print("=");
    Serial.print(cm[i]);
    Serial.print("cm ");
  }
  Serial.println();
}

I'm thinking it has to do with this timing, but I can't seem to get this to control my Serial.prints on the analog sensors

void oneSensorCycle() { // Sensor ping cycle complete, do something with the results.
  for (uint8_t i = 0; i < SONAR_NUM; i++) {
    Serial.print(i);
    Serial.print("=");
    Serial.print(cm[i]);
    Serial.print("cm ");
  }
