Simple & Easy Arduino Alarm Clock with DS1302 

Nice project dude! we'll try to do this project in our school and hope it works. More power to your channel!

A very useful video, short, clear, and most importantly useful, I downloaded the code, uploaded it to the Arduino and everything works, only in my case the LSD initialization looked like this: “lcd.init();” instead of "lcd.begin();" and I used Arduino Uno, thank you.

Hello , can used ds 1307? Or Need any changes in the code. You can make the reloj with rtc ds3231 in my country is very hard found the rtc 1302.

Nice one you are talented

Napakahusay Naman po Good job

thank you very much, it is very good project for beginner

Hello from 2024, I will like to know assuming I connect my Arduino through a Bluetooth module. How can I dynamically set the time instead of having it pre programmed. Thanks

I've included the I2C library u recommended in your previous video. I even deleted existing other I2C libraries. But still getting that library i2c.begin error. Plz help me

nice tutorial and project

May I know how to get the current date & time? When compile, by default it's showing 1st Jan 2000 instead of current one

what an awesome.content my homies

Thank you so much, very helful.

Nice making 👍 good job bro

Hi, I did everything you did but the lcd only display boxes on the top row and nothing on the bottom row. What should I do to fix this?

Nice lods keep safe gdbless

Galing naman po.

Good job

Beautiful project!!! But how do i activate alarm for only 3 seconds without me having to stop it using the button

We're almost done doing this clock but we have a problem. In our lcd, it shows 3:85:85 PM 45,2165 SAT What do you think is the problem? Please help us

Nice. Thank you so much 🙂

help me ,it is error exit status 1 no matching function for call to 'LiquidCrystal_I2C::begin()'

Hello, ive already connected the wires and uploded the codes, but my LCD still doesnt show anything just the buzzer that rings momentarily, pls help

same card same connections but have no matching function for call to 'LiquidCrystal_I2C::begin()' error. ı try all versions but not working

I double checked all my connections i am using arduino uno but lcd wont display text even if i adjust potentiometer... i even tested the lcd 1602a i2c individually and it does display an output.

thanks bro...

Wow, cool!

Hello, this project is excellent. I have a question I would like the alarm to sound every day without setting it daily, can help me

Hello, I am making an alarm clock that triggers a motor upon ringing. Any ideas on how to integrate a motor into this system?

i used ds3231 rtc module.when i upload the code the initial time didnt came as it as current time.i tried rtc sample code but buzzer didnt ring

Our buzzer doesn't work when its alarming. What do you think is the problem? please help us 🙏🙏

no matching function for call to LiquidCrystal_2C:begin()' however I did download the right library.

Hi why does our buzzer doesn't work when alarming? What do you think is the problem? Plss help us. Thank you.

@JR-ECT i am using a arduino uno can you tell me where to connect the jumper wire to the breadboard. Please let me know thank you.

diagnostics says 'virtuabotixRTC.h' file not found, after compilation, it says fatal error, and No such file or directory, can you help me?

i am geting only boxes on screen plz tell me how to fix it

Hi, i have a question, if you set up an alarm , will it be off after when it rings, or it will be repeated the next day? I need the answer asap, so if you have the answer please let me know, thanks in advance

Is there a way to integrate other melody instead of the buzzing sounds on the alarm clock? like a song melody for example? Anyways, great project bro keep it up!

hello JR-ECT I just opened the arduino code and when I press verify it says no matching function for call to "liquidcrystal_i2c::begin()" and what should i do? sorry my english is a bit bad

I set the time but it doesn't show up on the lcd display and the time doesn't move.

hello, can u make a video using arduino uno and please upload the codes. thank you

Will it work of you use a different RTC module?

Hello I use arduino uno and as I read everything should work fine but when i put everything together and upload the code the display shows only the squares like yours does in the video when you upload the code, but on mine the time never shows up. I hope maybe you could help please?

Does it save the time you set even after you unplug or lost of power supply?

I instead tried to mount a arduino uno on to the breadboard but it didn't work any suggestions please

Just wanna ask is the code same for arduino nano and arduino uno because I will need to change the nano to uno cause I don't have nano

sir how may i change the code to stop the alarm from deactivating once rung. I would like the alarm to ring everyday at the said time without the need to set it everyday

hi, can use ds3231 intead of ds1302 rtc?

pwede po ba i set yung repeat ng alarm? like tutunog ulit yung alarm every day or every monday-wednesday lang?

Hello! Did you use the Arduino Nano v3.0 CH340G microcontroller? Thank you

Hello, the lcd display doesn't seem to display any text after I uploaded the code to the arduino. Everything seems to work except there is no text on the lcd monitor.

.hellow po.. ang galing paturo po..

great project...congratulations...can I add about 50 events with different days and times???how do I do that??

Hi, can you help me about the LCD?

Hi , i have a question is this code will start well if i use i2c clock model?!????

Pls also put the link of website from where did you find all the libraries

Hello, I have a question. How to change 12h to 24h. Thank for response.

After uploading the codes, Lcd shows 12:00:00 AM 0/2000 What do you think is the problem? Please help us, this is for our project 🙏🙏🙏

I make this project for my sister birthday🙂. Then I change default time and date to current time and date, but they not update.😔 How can I fix that?🙄😕

Hey there My LCD just shows black boxes despite downloading the correct libraries and codes. Also I am doing this project wth Arduino UNO. Any suggestions?

My LCD only shows the white boxes, any idea why this is? Thank you!

Excellent Can you share the code

Thanks; Does it work with DS3231?

Can't add library file.. please help

Hi, thanks for sharing this with us. Please, can you help us to make a project?

is it possible to add more slots instead of just only 5 slots?

Paano Po kapag ds1307 rtc module Po

If i will make a timer, how source code, please...🙏🙏

buzzer it doesn't work with arduino why ?

Could you help me.How do I find your library?

Hello, i have successfully work it out !!! I was so happy, nice project too. But i wanted to test it on LCD without i2c, i changed the codes ( the libraries , void setup begin part, and backlight) and also changed the pins connection - RS = 12, en = 11, D4 = 5, d5 = 4, D6 = 3, D7 = 2 (LCD pins to Arduino Pins). The outcome is the LCD shows the alarm mode straight away and when i press the set button, the mode changes then goes back to alarm mode rapidly, the buzzer is ringing all the time as well. Do you know what's wrong with it?

Hello sir, can I ask why the code doesn't run? It says no file or directory. How can I fix it?

how about the cuckoo clock.. can you teach me ?

Please share the code

hello, if we're using a battery, what type of battery do you suggest? we can't find any answers on google, this is our last hope😭 thank you for making this vidd♥️♥️

Great project, but I can't download the code. Can you publish it as text or something like that? Thanks a lot! Bye!

can we use battery to power this circuit? if we can use, what kind of battery and where we will put it? pls reply 🙏

Code need my pls

Where is virtuabotics library

Not open this aurdino program

Please give me correct code

i can't find the file 'virtuabotixRTC.h' on internet ? (file, not only the text)

it used to work for you, now it doesn't ERROR lcd.init(); // initialize the lcd I wrote 16.2 there and it still doesn't work, it's broken Your program doesn't work anymore mate

Awesome video dude! I tried to execute your code but I get a message of warning: invalid conversion from 'int*' to 'int' [-fpermissive] EEPROM.write(addrActive, 0); can you help me with this? Thank you so much

the third button is not working, why?

ERROR lcd.init(); // initialize the lcd

Hello, can you please upload virtuabotixRTC.h library
