Hi, complete beginner here, I am trying to create a sunrise alarm based off this tutorial:
However, I would like to set 2 alarm times instead of one. How would I modify the app and the code in order to do so?
Code:
/*
Sjors Platjouw
Arduino ITTT
Sunrise Alarm clock with LCD Display and Bluetooth app
*/
#include <Wire.h> //De library voor I2C
#include <RTClib.h> //De library voor de klok
#include <LiquidCrystal_I2C.h> //De library voor het I2C scherm
LiquidCrystal_I2C lcd(0x27, 2, 1, 0, 4, 5, 6, 7, 3, POSITIVE);
#include <DS3231.h> //Include the clock library
// Changable Vars
int fadeTime = 1; // How long the light will fade to max
int setHour = 02; // Set hours to wake (military time)
int setMin = 49; // Set minute to wake
int uled = 9; // Set pinout with PWM
// Set up Vars
RTC_DS1307 RTC; //Definieer de klok als DS1307
DS3231 rtc(SDA, SCL);
Time t;
void start();
void start()
{
// Fix for SB LED
analogWrite(uled, 1);
delay((fadeTime * 60000)/50); // fade timers
analogWrite(uled, 2);
delay((fadeTime * 60000)/50);
analogWrite(uled, 3);
delay((fadeTime * 60000)/50);
analogWrite(uled, 4);
delay((fadeTime * 60000)/50);
analogWrite(uled, 4);
delay((fadeTime * 60000)/50);
analogWrite(uled, 5);
delay((fadeTime * 60000)/50);
// Fade script for the LED
for (int i = 6 ; i <= 255; i++)
{
analogWrite(uled, i);
delay(((fadeTime * 60000)/306));
// Serial.print(" mil sec ");
// Serial.print(((fadeTime * 60000)/306));
// Serial.print(" PWM " );
// Serial.print(i);
}
delay(20000); // Stay Bright
analogWrite(uled, 0); // Turn off
}
void setup()
{
Wire.begin();
pinMode(uled, OUTPUT); // Set pinmode
Serial.begin(9600); // Match to serial monitor
RTC.begin();
rtc.begin();
lcd.backlight();
lcd.begin(16, 2);
// uncomment these lines to set time, then reupload again without them.
// rtc.setDOW(THURSDAY); // Set Day-of-Week to SUNDAY
// rtc.setTime(02, 10, 0); // Set the time to 12:00:00 (24hr format)
// rtc.setDate(17, 1, 2019); // Set the date to January 1st, 2014
}
void loop()
{
String input = "";
while(Serial.available())
{
input += (char)Serial.read();
delay(5);
}
DateTime now = RTC.now();
lcd.setCursor(13,0); // Set text at 3,1 on display
char dateBuffer[12]; // Set databuffer
t = rtc.getTime(); // Make a time class called 't'
// Send Day-of-Week
// Serial.print(rtc.getDOWStr());
lcd.print(rtc.getDOWStr());
// Send date
// Serial.print(rtc.getDateStr());
lcd.setCursor(0,2);
lcd.print(rtc.getDateStr());
//sprintf(dateBuffer,"%02u-%02u-%02u ",now.day(),now.month(),now.year());
// Send time
// Serial.println(rtc.getTimeStr());
lcd.setCursor(0,0);
lcd.print(rtc.getTimeStr());
delay(1000); //Wacht 1 seconde (1000 milliseconden)
lcd.setCursor(3,0);
String firstHalf = getValue(input, ':', 0); // check first input untill ":"
String secondHalf = getValue(input, ':', 1); // check second input after ":"
// use this code if you're not using the bluetooth module
// //if (t.hour == setHour && t.min == setMin) // Check if it's time to wake up!
// {
// start();
// }
// check first 2 digits inputs, then check second 2 digits of input
if (t.hour == firstHalf.toInt() && t.min == secondHalf.toInt())
{
start();
}
}
// logic to seperate strings
String getValue(String data, char separator, int index)
{
int found = 0;
int strIndex[] = { 0, -1 };
int maxIndex = data.length() - 1;
for (int i = 0; i <= maxIndex && found <= index; i++) {
if (data.charAt(i) == separator || i == maxIndex) {
found++;
strIndex[0] = strIndex[1] + 1;
strIndex[1] = (i == maxIndex) ? i+1 : i;
}
}
return found > index ? data.substring(strIndex[0], strIndex[1]) : "";
}
