My house display for 2017 Christmas. The outside lights and living room window lights are controlled by an Allen Bradley SLC5/04 PLC. The door wreath is controlled by a Siemens S2-200 PLC, with the power to it controlled by the living room SLC5/04. Most of the light strings have been cut into 10 bulb sections to run on 24 volts DC provided by separate power supplies. The flickering candles in the kitchen window are 4 volt bulbs wired to a TTL transistor logic card, and each of the 7 is controlled with it's own subroutine. TO get 4 volts I have a 5 volt power supply run through a potentiometer

My 2017 Halloween display for a house I just bought this year. The living room and porch lights are controlled by an Allen Bradley SLC5/04 PLC, which is controlled by a SLC5/05 PLC that controls many home and security functions. The kitchen window is controlled by a SLC5/03 PLC. All PLC's are controlled by a computer and a Windows tablet running AdvancedHMI applications. The start & stop times and days can be changed, along with enabling and timing of specific items.
