Goals of Project
• 24 fully programmable outputs
• Up to 256 switch points
• The switch points are stored in flash memory, so there's no need for a backup battery
• The time is kept in sync with where don’t have to bother changing settings
• When daylight saving time is applied.
• Has an internal clock to bridge periods when no signal is available

Work Done
• The Design of remote is done using remote controller. The choice is made to select the RC5 Coding.
• The design circuit diagram was designed to control 24 devices as shown .
• The concept of RTC (Real time Clock ) to remotely program.
• The security options are created to lock from the station.

Algorithm
• Step 1 To switch ON the Cooling fans that are located at four positions. In the morning all the four fans must be ON they can be remotely programmed.
• Step 2 To switch ON the lights that are located at six positions. In the morning all the lights must be OFF they can be remotely programmed. (Save power)
• Step 3 To switch ON the tower red light that is located at top position of station. In the night must be ON they can be remotely programmed. Indicate Obstruction to Aircraft)
• Step 4 The status of devices can be seen using on an LCD and the locking facility for security can be done.
