Scenario 1 Turn on a light when either one of two switches (I1, I2) is toggled on (construct an OR Gate). Turn on a second light when both switches (Same inputs I1, I2) are toggled on (construct an AND Gate). Turn on a third light when both switches (Same inputs I1, I2) are toggled off (construct a NOR Gate). Turn on a fourth light when either switch (Same inputs I1, I2) is toggled off (construct a NAND Gate). Print a copy of the program showing the construction of the four gate configurations. Also, submit a truth table for the four input configurations. Then modify your program so, only one light turns on at a time as you toggle the four truth table states.

Scenario 1
Turn on a light when either one of two switches (I1, I2) is toggled on (construct an OR Gate). Turn on a second light when both switches (Same inputs I1, I2) are toggled on (construct an AND Gate). Turn on a third light when both switches (Same inputs I1, I2) are toggled off (construct a NOR Gate). Turn on a fourth light when either switch (Same inputs I1, I2) is toggled off (construct a NAND Gate). Print a copy of the program showing the construction of the four gate configurations. Also, submit a truth table for the four input configurations.
Then modify your program so, only one light turns on at a time as you toggle the four truth table states.
Scenario 2
Construct a seal-in circuit using a stop-and-start pushbutton and an internal coil to seal in. Turn on a light for 10 seconds when the start button is pushed then turn it off automatically or when the stop button is pushed.
Scenario 3
Program a blinking light sequence using 2 on-delay timers. The light should turn on for 2 seconds and off for two seconds. Program a second blinking light sequence using a timer on delay and a timer off delay.
