The function of our project is a light control system The lights can be controlled at two different frequencies or speeds and on two different patterns There is a simple user interface consisting of two switches and two push button switches The user can choose to run the lights slowly or quickly by flipping a switch The user can also choose one of two different modes in which the lights will run by flipping another switch The system uses 4 volts of electricity and therefore can be left running for a long time with the much power consumption For the sake of simplicity all work project uses only two different color lights but more colors can be implemented The idea is to use a small number of chips to produce a large output Our project uses five D flip-flops as well as four XOR gates With two 555 timers the flip-flops can be used as counters at two different speeds The output of each flip-flop is connected to four LEDs that produces a running effect when turned on Our project is for decoration purposes When power is provided the light control system begins to work on its own From here the use can select the speed at which he or she wants the lights to operate as well as select the pattern of choice If at any time they user wishes to check for burnt lights he or she can press the ALL ON button and all the lights will come on Using the switch labeled SPEED CONTROL the user can select at which rate the lights should move Using the PATTERN switch the user can select the pattern of choice If at any time the user feels the lights are not running as they should he or she can reset the lights using the RESET button Using both combinational and sequential logic we have put together
