good evening all, i have an issue with my alarm clock arduino...... i have built a project with an alarm clock with arduino ..... i am using ds1307 with arduino and an 1602 display ...... and also a buzzer what i encounter is tha the clock is working and i get an alarm at 10 minutes but not at 1…

Sorry your question does not give me enough information. Can you post your schematic and try to explain to an old timer what you are asking?

[image] spectrum1982gr: if (alarm==15) { for (int i=1;i<=10;i++) { for (int g=1;g<=30;g++) { digitalWrite(buzzer,HIGH); delay(1); digitalWrite(buzzer,HIGH); delay(1); } } } Should the second digitalWrite be LOW? Also in 18?

[image] spectrum1982gr: lcd.print(alarm); Do you see the lcd print for 10, 15, and 18?

yes i will ... i need some time to draw it ty

yes it should be low ...... i will try it now ty in advance

i see the 10 minutes only alarm not the other ..... looks like if statement for 15 and 18 minutes is not working ty

[image] spectrum1982gr: i see the 10 minutes only alarm The delay(1000) coupled with incrementing alarm when seconds is exactly 59 makes me think you are missing some increments. Try printing the value of alarm and see if it does ever get to 15 and 18. Also I don't see where you reset alarm …

good evening..... i dont reset alarm to zero because i dont need it too...... i use the alarm to count only to infinitive minutes...... i use it only to see the time and i manually close power to reset it for example if i use it to count time for some reason i manually power it off also..... ano…

[image] alto777: Try printing the value of alarm and see if it does ever get to 15 and 18. Did you ever do this? if i change rtc.second to 60 then i never get inside the if statement to increase the alarm variable i dont know why thats why i changed it to 59 I believe that the seconds r…
