the code is not functioning correctly no matching function for call to 'LiquidCrystal_I2C::LiquidCrystal_I2C(int, int, int, int, int, int, int, int)' always they show this message
Great project. Thank you. I have tested with simple single switch on X4Y1 (row 4, column 1) to use set time function only presently. I am wondering as the A,B,C,D not used on the keypad, may I use a 3x4 keypad without connecting that column? Again, great project.
Hello, I can't remember if this code contains a set time function at the beginning with fixed values, but if it is upload the code the first time with correct date/time and then reupload the code without that line. The line is probably mentionned in the code.
Hai. Can you help me? What if i want to make some alarm clock. And the keypad is use to set the clock at certain time. Let say, i enter on the keypad 0730. And then if the time matches, from the arduino there is output to the buzzer. Can you help me?
Hello, the key inputs are read as "char" but in order to do some maths manipulations we need to convert them to "int". 0 as char = 48 as int. Check this ASCIIchart to know more www.arduino.cc/en/Reference/ASCIIchart
Hello, in the link bellow the video you'll find the article about the project in my website, then bellow the wiring you'll find links to download libraries needed and the code (those links direct you to google drive where you can find the files). Otherwise here's the link to the file in Drive ( drive.google.com/file/d/1rqX5Xb24vn3zj5mSVZl5hlZLIxJ1apcX/ )
@@SurtrTech It's because he can't decompress a .RAR file. Who uses .RAR files anymore? They are obsolete. Why not just make the .ino file available uncompressed?
@@chuckhole I'm uploading them as .ino in new videos, those are just the old ones, and for the libraries the .RAR is very common, so it's better to have Winrar
Hello Friend.
as I put the day of the week. because I liked it very much.
Day of the week has its own variable too "dayofweek", it displays numbers, you can change it to days names if you want
the code is not functioning correctly
no matching function for call to 'LiquidCrystal_I2C::LiquidCrystal_I2C(int, int, int, int, int, int, int, int)'
always they show this message
thank you very much
I have one question. How can i read string from my entered time from keypad and set that time to start my servo spinning???

Yes you can do, you need to adjust the keypad declaration... and change the buttons to '*' or '#'... check on 4x3 keypad examples to help you.
@@SurtrTech Thank you for the reply. Will try.😊
Thanks for this video! It was be so useful for me
Can I use the same library for ESP32?
Will it work without errors?

hello @sutrtech Could you help me? my Rtc1302 is not storing time. When reboot, it goes to default time. thank you

@@SurtrTech i tried but still not holding time.
@@shahidmuneer6010 Did you check if the battery is working well or depleted?
Yes i have tried with new one also...I am using CR2030
How about with RTC DS1307, plz ._.

if the time match, the buzzer will make sound.
Hello, I already have the code and wiring for this, I will do a video about it as soon as possible stay tuned.
Hi I tried to do this, check the new video about it ua-cam.com/video/62tHrqMM55w/v-deo.html
Hi. How could i contact you? i really need your help. ive sent also a pm in your fb page
Hey I didn' understand What is it -48 ??
for example:
i1=(c1-48)*10;
i2=c2-48;
int N_hour=i1+i2;
Hello, the key inputs are read as "char" but in order to do some maths manipulations we need to convert them to "int".
0 as char = 48 as int.

@@SurtrTech Thank you bro it worked for me.
Johnny Johnny.... Ahhhhhh, so this is how u became a keyboard warrior 😂🤣🙏
Can solve pls
what can i do if i dont have the backpack???
Sorry I don't understand your question? "backpack"?
thx for the help ^_^
Pleace code..
hello can I get the codes for this project please
The link below the video you'll find wiring, libraries and code.
Why date and clock not display like
0/0/2000
0:0:0 like but i done setup but still this
Check the wiring and soldered pins, also if you could add a resistor between DAT and its pin, 1k 2.2k 220Ohm can do it
cant" download that code
