Ich habe eine Schaltung aufgebaut und die Temperaturen wurden korrekt auf dem Display ausgegeben. Plötzlich zeigt er es auf keinen Arduino Nano mehr an. Habe 3 Stk getestet. Auf einem Mega funktioniert es. Hat jemand eine Idee?
Hier der Code:
#include "Arduino.h"
#include "Wire.h"
#include "OneWire.h"
#include "MicroLCD.h" //OLED
#include "DallasTemperature.h" //DS18B20
//Aussenfühler
#define DS18B20 2
OneWire ourWire(DS18B20);
DallasTemperature sensors(&ourWire);
//OLED
LCD_SSD1306 lcd; /* for SSD1306 OLED module */
//Temp+Hum Sensor
#include <SimpleDHT.h>
int pinDHT11 = 5;
SimpleDHT11 dht11;
//MQ-2 Sensor (LPG)
#include <MQ2.h>
//change this with the pin that you use
int pin = A0;
int lpg, co, smoke;
MQ2 mq2(pin);
#include <Ultrasonic.h>
Ultrasonic ultrasonic(12, 13);
void setup()
{
lcd.begin();
sensors.begin();
mq2.begin();
Serial.begin(9600);
}
void loop()
{
//Ultraschall
Serial.print("Distance in CM: ");
// Pass INC as a parameter to get the distance in inches
Serial.println(ultrasonic.distanceRead());
int Fuellstand;
Fuellstand = map (ultrasonic.distanceRead(), 5, 26, 100,0);
//DS18B20
sensors.requestTemperatures();
//DHT11
//Serial.println("=================================");
//Serial.println("Sample DHT11...");
//read without samples.
byte temperature = 0;
byte humidity = 0;
int err = SimpleDHTErrSuccess;
if ((err = dht11.read(pinDHT11, &temperature, &humidity, NULL)) != SimpleDHTErrSuccess) {
//Serial.print("Read DHT11 failed, err="); Serial.println(err);delay(10);
//Serial.print("Sample OK: ");
//Serial.print((int)temperature); Serial.print(" *C, ");
//Serial.print((int)humidity); Serial.println(" H");
return;
}
float* values= mq2.read(true); //set it false if you don't want to print the values in the Serial
//lpg = values[0];
lpg = mq2.readLPG();
//co = values[1];
