Arduino Tutorial #25 How to make Arduino Alarm Clock.

[@julianemalobago]

hi, what type of jumper wires did you use? m to m, f to f, or m to f? i need your reply, ASAP please.

[@ahmadhaziq3514]

thank you for your work ..now i have some idea for my pill box reminder :)

[@Lolaneer]

I'm having a problem where set time and date don't work when I run the code. The LCD screen stays at 00:00:00 for time and 00.00.2000 for the date even when i change it on the rtc.setTime and rtc.setDate lines.

[@RoboticaDIY]

first uncomment the lines (if it is comment out), set the time & upload the code and again comment out those line (which i showed in video) then again upload the code.

[@Israeliyanuoluwaadebisi]

Hi, pls i need an alarm system that can set up to 5 alarms only, nothing added just for alarm purposes.

[@mdafroz4190]

Can we make multiple alarm in code plz tell me

[@jeonheejinie]

how can I add a stop button for the alarm buzzer to stop? it keeps going until a minute passes by...

[@mscookie2112]

Hi! Did you use only F/F and M/M jumper wires or you used the hybrid ones as well? (I mean the F/M ones)

[@chaos5224]

I downloaded the library for the DS1302 and liquidcrystal_I2C, but i got error says that there is no matching for call to ‘liquidcrystal_I2C::begin()’

[@thisislolipop1177]

Thx I used ur idea for my test, helped me a lot

[@billystonecliffe7762]

nice, i think i'm going to replace the speaker with a water pump tho, to make sure i get up

[@ArmenMikaelian-e7i]

Did you ever end up doing this because I have a project for school and need to build a water alarm clock.

[@RahulJain-rj6jw]

You are the best , your code is so simple and easy to understand. It really helped me a lot. Thank you man.

[@RoboticaDIY]

Glad to hear that!

[@julianemalobago]

how did you do the coding? mine is not working.

[@electronicspassionchannel6622]

Which lines of code save the alarm status on ?

[@rushabhchauhan]

can i increase the alarm tone time?. mean,now it is just ringing 1min. i want increas it

[@MrBobWareham]

Thank you for sharing your clock I want to make one but don't want to use the I2C backpack on the display so can I just connect the display to the Arduino please as I don't have that part, thank you for your time Bob in the UK

[@RoboticaDIY]

Hi Bob, I wrote code for you (without I2C alarm clock) (But didn't tested on hardware), let me know it is working for you or not. for connection LCD to Arduino you can see roboticadiy.com/how-to-make-counter-using-motion-detection-sensor-pir-with-lcd/

Thank you, Bob

Please try to slow down the arranging part

We are mere beginners

[@RoboticaDIY]

@@ksraahul5430 Thanks for your valuable feedback. I was thinking, not to waste my audience time by useless clips. but you are right it is bit fast.

[@YouTube_stole_my_handle]

You can change playback speed to slower

[@eldormazhidov2877]

what kind of libraries i need?

[@samimra3297]

Hello sir i have a problem in code the Time t; has error
no matching function for call to 'Time::Time()

[@nisayumlu7814]

please add the I2C library. thank you

[@mamatata8096]

hey bro can i make when i press button it trun alarm off i tried but it just wont turn off

[@chaos5224]

Hey
Can i take a look at your code if it is alright with you.

[@reanews1]

Hi. Thank you for your work. How to make an alarm clock ring every day?

[@RoboticaDIY]

Hi. it will ring every day on exact same time...

[@walteradiaton5326]

Got a problem about the code it says that 'class DS1302' has no member named 'WriteProtect', how can i fix this?

[@jgaming0523]

What about using ds1307 instead of ds1302?

[@RoboticaDIY]

Yes, you can use ds1307. library and ds1307 connection will be changed.

[@msaeedanwar9495]

Is more then 5 alarm can be set on this.

[@RoboticaDIY]

you can set any number of alarms.

[@msaeedanwar9495]

Thanks

[@amberlevesque999]

Hi, would this code and schematic work with the DS3231 if I included the library for it instead of the library for the DS1307? Thanks in advance!

[@RoboticaDIY]

yes it would work. but do changes according to DS3231 code.

[@theelanfrost8249]

Thanks for your work! Its running properly :) one thing, how to change 24hrs format to 12hrs format? :)

[@RoboticaDIY]

to convert 24hr to 12 hr format. you just have to minus 12 from hour, if you dont understand this, i will make a video on this soon :) ...

[@theelanfrost8249]

Robotica DIY thank yo for your response :) appreciated and I'm looking forward to your next vid.

[@theelanfrost8249]

well, what I mean is the format of rtc.setTime (12, 59, 00) 24hrs right? how to convert it to 12hrs. :) so it will show like this 12:59:59 ... 01:00:00, it always show like this 12:59:59....13:00:00

[@RoboticaDIY]

yes i understood what you are asking.. just minus 12 from hour. there is some flaws which we have to solve with coding. i will make video on that within this week.

[@RoboticaDIY]

@TheeLan Frost I am busy right now so i couldnt make video but i am sending code for you. it works fine i have tested it.

hi i tried this connection but it seems the only sound is operating well. My LCD does not show anything and i rechecked it a lot but it is just blank.
what can i do with this problem?

Same as mine does it mean it must have a specific model lcd?
