IF statement with multiple conditions for Oled

[souvikroyc]

Need help with multiple if statement.

#include <Wire.h>
#include <Adafruit_GFX.h>
#include <Adafruit_SSD1306.h>
#include <DS3231.h>

DS3231  rtc(SDA, SCL);
Time t;

void setup() {
  Serial.begin(115200);

  display.begin(SSD1306_SWITCHCAPVCC, 0x3C);
  display.setTextSize(1);
  display.setTextColor(WHITE);
  display.display();
  display.clearDisplay();

  rtc.begin();
  // The following lines can be uncommented to set the date and time
  //After uploading comment back and upload to make static values to that it does not changed after every bootup.
  // rtc.setDOW(WEDNESDAY);     // Set Day-of-Week to SUNDAY
 // rtc.setTime(3, 25, 55);     // Set the time to 12:00:00 (24hr format)
  // rtc.setDate(11, 10, 2021);   // Set the date to January 1st, 2014 (DD,MM,YYYY)

//*************************End of void Setup************************

void loop() {
  Serial.println(rtc.getTimeStr());

  if (t.hour >= 8 && t.hour <= 9) {
    Serial.println ("SUNRISE");
    display.setCursor(80, 20);
    display.print("SUNRISE" );
  }

  else if (t.hour >= 21 && t.hour <= 6) {
    Serial.println ("MOONLIGHT");
    display.setCursor(80, 20);
    display.print("MOONLIGHT" );
  }

  else  {
    Serial.println ("OFF");
    display.setCursor(80, 20);
    display.print(" OFF");
  }
  display.display();
  display.clearDisplay();

}


//*************************End of void loop************************

Do you have a question?

[souvikroyc]

yes display is not printing the status during given period of time. seems like something stuck in void loop. the program is not progressing with if and else if statements.

[wildbill]

Your display showing nothing doesn't seem surprising:

  display.display();
  display.clearDisplay();

Send stuff and immediately clear it?

[souvikroyc]

yes exactly.. it shld verify the time given in If statement from RTC whenever it passes through.
