🔒 Closed DS3231 - Code that repeat for given no. of X days? Arduino Project

[AEZAKMI_12]

Good Day mga paps, medyo baguhan lang ako sa arduino, lalo na sa DS3231 RTC Module kaya di ko rin alam kung pano gagawin

Gusto ko gumawa ng loop kung saan iseset ng users kung ilang days nila gusto mag repeat. Let say nag input si user ng "3", edi mag rerepeat dapat ng 3 days yun.

Basically gagawa ako ng Pet Feeder kung saan yung users pwedeng
A. Set the time WITHIN the day when they want to feed it ONCE
B. Set the no. of days they want to repeat the process of feeding at certain time(the time will be specified within the code, so the user will only set the no. of days).

Bali sa part na to ako nahihirapan, di ko alam kung pano gagawin. Baka alam nyo kung pano, patulong naman

void setFeedingDate(){
 //No code yet. Sad emoji
}

Eto yung full code ko

#include <Servo.h>
#include <LiquidCrystal_I2C.h>
#include <Keypad.h>

const byte ROWS = 4; // Four rows
const byte COLS = 4; // Three columns

// Define the Keymap
char keys[ROWS][COLS] = {
  {'1', '2', '3', 'A'},
  {'4', '5', '6', 'B'},
  {'7', '8', '9', 'C'},
  {'*', '0', '#', 'D'}
};


byte rowPins[ROWS] = { 2, 3, 4, 5 };// Connect keypad ROW0, ROW1, ROW2 and ROW3 to these Arduino pins.
byte colPins[COLS] = { 6, 7, 8, 9 };// Connect keypad COL0, COL1 and COL2 to these Arduino pins.

//  Create the Keypad
Keypad kpd = Keypad( makeKeymap(keys), rowPins, colPins, ROWS, COLS );
