In this exercise, I learned how to use a single throw switch to turn on the LED as well as using a double throw switch located at the top of the picture. Here, when both switches are giving the same output, the LED will like up. However if the switches are feeding opposite power signals, the LED will shut off. This simulation is a lot like how some hallway lights work where there are two switches at the ends of a hallway.
From this exercise, the same principle applies, but this time, a relay is used. The relay works by switching the ground and positive signals to oscillate between two points of a circuit board. To demonstrate, the button on the left is left alone which indicates that the ground is going to the relay and thus completing the circuit for the green LED. And the red indicates that there is an incomplete circuity and thus no light will show.
After hitting the switch tho, we can clearly see that the positive signal is transferred to the relay completing the circuit for the red bulb, and sending power to the relay to the green which makes it an incomplete circuit.
