It is a Hardware CRON-LIKE Scheduler
- Scheduling of AC Sockets using a modified CRON syntax.
- Input of Schedule can be from the Removable Serially connected LCD Keypad Module or through the PC Interface via USB.
- Schedule will be stored on the PIC18F4550 EEPROM if the size fits. Others will be stored on a memory card.
- An SD Card Slot can be added using via SPI to the PIC18F4550.
