We use PC’s serial port to interface microcontroller. The hardware also has a 64K EEPROM chip AT24C64. This EEPROM is used to store the timings and messages to be displayed. Hardware also contains a real time clock DS1307 to maintain track of time. Both these ICs are interfaced with microcontroller using I2C interface. The keypad is used to set/reset parameters directly. A 4x4 keypad is attached using Row Column configuration. A 16x2 Character LCD display is attached in byte mode to port 1 of microcontroller
