Lab 0 - A Simple Circuit to Light an LED

In this lab, you will pair with another student in the class to build a simple circuit to light a light emitting diode (LED) in response to  pressing and releasing a push button switch. To complete this lab, you will need the following materials in the following quantities:

Materials:

1X Breadboard for circuit prototyping

1X 9V battery

1X 9V battery snap connector

1X LED (color of your choice)

1X Push button

1X Current limiting resistor

Objectives:

1. Draw a circuit diagram for a circuit in which pressing and holding the push button will light the LED indefinitely (ie. the LED component does not burn out).
2. Construct and test the circuit from 1. When it is working demonstrate the functionality for the professor or a ninja.
3. Draw a circuit diagram for a circuit in which the LED is continuously lit when the button is not pressed and pressing and holding the push button will turn the LED off.
4. Construct and test the circuit from 3. Once again, demonstrate the functional circuit for the professor or a ninja.
