Engine + Sensors

[12laure]

Hello,
In my project, I want to get on the serial monitor of the arduino IDE the data of two sensors (BMP280 and Sharp IR ) and in addition to make a servomotor turn.
The problem is that the motor turns correctly but I receive the data only once and not every second. I don't see where the error is in my program.

#include <Wire.h>
#include <SPI.h>
#include <Adafruit_BMP280.h>
#include <Servo.h>

#define BMP_SCK (13)
#define BMP_MISO (12)
#define BMP_MOSI (11)
#define BMP_CS (10)

Servo myservo;
int pos = 0;

int Capteur_distance = A0;

Adafruit_BMP280 bmp; // I2C

void setup() {
myservo.attach(9);

Serial.begin(9600);
Serial.println(F("BMP280 test"));

//if (!bmp.begin(BMP280_ADDRESS_ALT, BMP280_CHIPID)) {
if (!bmp.begin()) {
Serial.println(F("Could not find a valid BMP280 sensor, check wiring or "
"try a different address!"));
while (1) delay(10);
}

bmp.setSampling(Adafruit_BMP280::MODE_NORMAL,
Adafruit_BMP280::SAMPLING_X2,
Adafruit_BMP280::SAMPLING_X16,
Adafruit_BMP280::FILTER_X16,
Adafruit_BMP280::STANDBY_MS_500);
}

void loop() {

float volts = analogRead(Capteur_distance) * 0.0048828125;
int distance = 5 * pow (volts, -1);

Serial.print (distance);
Serial.print(",");

Serial.print(bmp.readTemperature());
Serial.print(",");

Serial.print(bmp.readPressure());
Serial.print(",");

Serial.print(bmp.readAltitude(1013.25)); /* Adjusted to local forecast! */
Serial.println();

delay(1000);

for (pos = 0; pos <= 90; pos += 1) {
// in steps of 1 degree
myservo.write(pos);
delay(200);
}

for (pos = 90; pos >= 0; pos -= 1) {
myservo.write(pos);
delay(200);
}
}

Thanks for your advice.

for (pos = 0; pos <= 90; pos += 1) {
// in steps of 1 degree
myservo.write(pos);
delay(200);
}

but I receive the data only once and not every second.

That for loop (and the other one) block execution for 18 seconds, each. So, yeah, getting data every second will be problematic.

Maybe investigate millis() non-blocking timing.
