hi
I TRY to write the code.
there is functional.
but it can be improved.
I am interested in any help.
thank

hi
Exactly, it is necessary to delete the function clock.
. but I do not know the language C for arduino .
I sorryhi
I not understand
if switch on, the clock is open
for go to the contdown, you must push on button DET.
your select the time of countdown with button Hours and minute
and if you want to lauch the countdown, you must push on button DET again.I search to make …
if switch on , the clock is not open but the countdown is open
your select the time of countdown with button Hours and minute
and if you want to lauch the countdown, you must push on button DETit’s possible ?
didierhi michael
I thinkIF contdown =00:00 then digitalWrite(A1, HIGH)
or
IF contdown =00:00 then digitalWrite(A1,low)
but where I put this code ?hi michael,
I do not know the langag of programming C
How to recuperer the value comptdown=00:00
didierHI
I wish to connect a siren and a revolving light. (8 in 12v with 1A).
They will be commanded when the countdown arrives at 00.00.Can you say to yourself the line of code to get back the value of the countdown which arrives in 00:00
thank you
didier
