On this day we worked with switches and relays. The relay is given power to the center pin and it switches the internal mechanism to continue the circuit.
The top picture shows the LED off because the switches are set so that the current is being interrupted by the lack of connectivity by the switch on the right.
The LED is now light because the switches are completing the circuit and allowing the flow of power to go through the power supply to the first switch to the second switch then to the resistor and to the LED that is grounded back to the power supply.
The red LED is on but if we want the green LED to turn on we need to power the relay through the moddle pin to make the seesaw like mechanism of the relay to switch from powering the red LED powering the green LED. This is done by pressing the push button that allows the power to continue to the center pin of the relay.
Here you see my gigantic finger pressing the push button that is allowing the circuit to be completed and powers the green LED.
