Arduino Tutorial 35- Real Time Clock using DS1302 RTC Module 

thankyou very much sir you save us from our prelim examination

I appreciate your help bro you explained so perfectly I wish I can subscribe as many times as I feel 🙏👍👍👍👍

WOW THIS WAS THE ONLY VIDEO WHICH EXPLAINED EVERYTHING **PERFECTLY** SO UNDERATED

muchas gracias, esta super bien explicado, lo entendi hasta yo que casi no entiendo el idioma, que gran contenido.

Really good tutorial, thanks

Thank you so much for your video. The analog pins that were used for the LCD, are it not possible to use them again for another module? Because I need more analog pins for my moisture modules.

You can change the date & time?

Yeah boiiiii

thank youuuuuu❤

gracias boliviano :D

you can do it with a 7 segment display PLEASE

In the video you said the DS1302 would take the time and date from the computer but my clock sometimes says "Enter year" and sometimes "Date: 165/165/21" "Time 37:65:85" + in the .zip that you put there's a picture called "keypad-circuit.jpg" and the code has the keypad library

The code doesn't match with the video. I asked chatGPT to write a code for setting up the reat time clock with the same pins as the pins this video used. Just change some codes like Serial.print to lcd.print. #include #include // Define the pin numbers #define PIN_ENA 8 #define PIN_CLK 6 #define PIN_DAT 7 // DS1302 RTC instance Ds1302 rtc(PIN_ENA, PIN_CLK, PIN_DAT); void setup() { Serial.begin(9600); // Initialize the RTC rtc.init(); // Test if clock is halted and set a date-time to start it if (rtc.isHalted()) { Serial.println("RTC is halted. Setting time..."); Ds1302::DateTime dt = { .year = 24, // Set the year to 2024 .month = Ds1302::MONTH_MAY, // Set the month to May .day = 19, // Set the day to 19 .hour = 21, // Set the hour to 21 .minute = 9, // Set the minute to 9 .second = 41, // Set the second to 41 .dow = Ds1302::DOW_SUN // Set the day of the week to Sunday }; rtc.setDateTime(&dt); } } void loop() { // Get the current time Ds1302::DateTime now; rtc.getDateTime(&now); static uint8_t last_second = 0; if (last_second != now.second) { last_second = now.second; // Print the date and time in the format "YYYY/MM/DD HH:MM:SS" Serial.print("20"); Serial.print(now.year); // 00-99 Serial.print('/'); if (now.month < 10) Serial.print('0'); Serial.print(now.month); // 01-12 Serial.print('/'); if (now.day < 10) Serial.print('0'); Serial.print(now.day); // 01-31 Serial.print(' '); if (now.hour < 10) Serial.print('0'); Serial.print(now.hour); // 00-23 Serial.print(':'); if (now.minute < 10) Serial.print('0'); Serial.print(now.minute); // 00-59 Serial.print(':'); if (now.second < 10) Serial.print('0'); Serial.println(now.second); // 00-59 } delay(100); }

How to introduce alarmes plz?

HOW MUCH IS A DS1302 RTC COST IN SRI LANKA

1307. Use. Honga ki nahi. 1302 se.

why your codes are the same in your project files?

why doesnt it show the keypad library? am i supposed to delete that one?

How do I get a Parts list??

PIN 1 》GROUND PIN 2 》POSITIVE PIN 3 》10K POT PIN 4 》A12 PIN 5 》GROUND PIN 6 》A11 PIN 11 》A5 PIN 12 》A4 PIN 13 》A3 PIN 14 》A2 PIN 15 》220Ω PIN 16 》GROUND

can you simulate proteus , please

the code says it uploaded but nothing changes on the lcd, any ideas? I am sure the com is right

which library?

sir can I ask why my time and date is wrong

Sir, what is the time format, is it in the military time?

Dear Friend: First of all, thank you very much for sharing your knowledge. Please, would there be a possibility of facilitating the program of said project? Waiting for your news, receive a cordial greeting from the Canary Islands (Spain)......

RtcDateTime currenTime = RtcDateTime(_DATE_ , _TIME_); Rtc.SetDateTime(currentTime); this is an error for me pls help :(

i used two time module...why my 1st module displays only the 0/0/2000 0:0:0 and the other module is 165/165/2165 and 37:165:85

I can’t see my time, help me pls?

My code is not working

Bro please sent this audino code

Can you share your codes, please?

Bro please this code for 2024

Bro please send this cose

clickbait

Can u pls send code
