Microcontroller › 8051 › 8051 alarm clock
Hi I’m building an alarm clock for my desk using the 8051 and ds12887 or just an 8051. I saw some samples and codes, but I want to have more than one alarm on different outputs, so I can have different sound for each alarm. For example one in the morning for a break, the second one at noon for lunch and the third one in the afternoon for a break. Plus a count down to activate a buzzer every 72 hours or 120 Monday trough Friday. I will really appreciate any suggestion. Thanks in advance
just checkout these links

and for count down you can use the counter mode of timer of 8051
Thanks a lot for you references and uggestions.
But I’m a beginner in microcontroller and programming and I need more detail.
For example if I use the code for the digital alarm clock and thermometer, and I’m going to add more than one alarm to the default code what do I need to do?
Do I need to use different addresses for example pin 8(P1.7) is the output of the alarm, but if I want to have alarm1 with an output at pin 8(1.7), alarm2 pin 7(1.6), and alarm3 pin6 (1.5). do I need to copy the same code for an alarm and update to each alarm’s output.
Thank in advance for your time and effort.
