PIC24FJ64 Multifunctional Alarm Clock
I’m sure that everyone has alarm clock in their house from the simple to the elaborate, to help them get a start on the day. But you need to be there to set it. DJ Delorie has design Multifunctional Alarm Clock that has three primary features: automatic time setting on power-up, remote management and streaming MP3 music.
At the core of this alarm clock project is the PIC24FJ64, which is connected to a wide range of support circuits: an ENC28J60 Ethernet chip to connect to a local network, an mp3 decoder chip to play music streaming off the Internet, an organic LED graphical display, and a 24LC512 EEPROM for storing alarm data, fonts, and images. A photocell and seven buttons are monitored via ADC inputs, and the music volume is both monitored and overridden via a single pin used as both an ADC input and a GPIO output. Various power supplies and an ICP port complete the circuitry.
