Problem 7 Segments Display - Solved.

Projects General Guidance

I use RTC3231 and a temperature sensor DS18B20 and display-TM1637
I don't know how to do this - First, show the time on the display. Then show the temperature.
Please help me if possible. Thanks.

#include <OneWire.h>
#include <DallasTemperature.h>
#include <TM1637Display.h>
#include "RTClib.h"
#define ONE_WIRE_BUS 1 //Digital Pin to connect the DS18B20 Sensor

OneWire oneWire(ONE_WIRE_BUS);
DallasTemperature sensors(&oneWire);
DeviceAddress sensor1;

TM1637Display display(9,8);

const uint8_t DEGREES[] = {
0x0, 0x0,
SEG_A | SEG_B | SEG_G | SEG_F,    // Degree Symbol
SEG_A | SEG_F | SEG_E | SEG_D,    // C
};

unsigned int temperature = 0;
byte PreviousValue = 0;
RTC_DS3231 rtc;

void setup()
{
sensors.begin();


if (!sensors.getAddress(sensor1, 0))
{
 Serial.println("Sensor not found!");
}
// Check if RTC is connected correctly:
if (! rtc.begin()) {
 Serial.println("Couldn't find RTC");
 while (1);
}
// Check if the RTC lost power and if so, set the time:
if (rtc.lostPower()) {
 Serial.println("RTC lost power, lets set the time!");
 // The following line sets the RTC to the date & time this sketch was compiled:
 // rtc.adjust(DateTime(F(__DATE__), F(__TIME__)));
 // This line sets the RTC with an explicit date & time, for example to set
 // January 21, 2014 at 3am you would call:
 //rtc.adjust(DateTime(2014, 1, 21, 3, 0, 0));
}
// Set the display brightness (0-7):
display.setBrightness(5);
// Clear the display:
display.clear();

}

void loop()
{
sensors.requestTemperatures();
int tempC = sensors.getTempC(sensor1);
if (tempC != PreviousValue)
 PreviousValue = tempC;
DateTime now = rtc.now();
int displaytime = (now.hour() * 100) + now.minute();

display.showNumberDecEx(displaytime, 0b11100000, true);
delay(1000);
display.showNumberDec(displaytime, true);
delay(2000);
display.setSegments(DEGREES); //Display the Variable value
display.showNumberDec(tempC, false, 2, 0);
delay(1000);

}

The problem is solved.
It showed only the hour. The temperature did not appear on the display. But all is well. I changed
#define ONE_WIRE_BUS 1 to
#define ONE_WIRE_BUS 4
Thank you all for your help.

It depends on what it is doing and what it is supposed to do.

Here are some tips on how to properly post your code, and more. Start with that.

Why would you connect a one wire bus to the serial port on pin 1? :astonished:

5

Please describe what the code actually does and how that differs from what you want it to do.
