=__Name of Circuit: Flashing LED__=

- Function of the circuit: The function of this circuit is to make the LED flash, but not stay lighted up. To do this, you must carefully follow the directions in the book. The wires, resistors, capacitors and LED's must be placed in the correct place in order for the circuit to be succesful.

- Components used in the circuit (listing with basic definitions):

 Wires-a strand of metal, usually copper, that is encased in plastic or another insulating material and is used to carry an electric current **Integrated circuit**- a tiny complex of electronic components contained on a thin chip or wafer of semiconducting material **Resistors**-a component of an electrical circuit that has resistance and is used to control the flow of electric current **Capacitor**-an electrical component, used to store a charge temporarily, consisting of two conducting surfaces separated by a nonconductor dielectric
 * LED -** (Light Emitting Diode) It flashes if we construct our circuit correctly.

- Explanation of difficulties encountered while creating the circuit:

There were also many difficulties that we encountered while creating this circuit. One of the main difficulties that was discovered, was that the LED would light up, but not flash, In order to fix this the integrated circuit was changed. This was a very difficult task to complete because there are many small parts, and different places that the parts could go in, so it was very important to be very precise and neat.

Picture one: Breadboard with LED Flasher

Picture Two: LED This is what the Flashing LED looked like in the breadboard circuit breaker, the LED we used was green.

Picture Three: we also used resistors to create this circuit.

=**__Name of Circuit: 555 buzzer__**=

- Function of the circuit: - Components used in the circuit (listing with basic definitions):

**Integrated circuit**- a tiny complex of electronic components contained on a thin chip or wafer of semiconducting material **Resistors**-a component of an electrical circuit that has resistance and is used to control the flow of electric current **Buzzer-**an electronic device that makes a humming or buzzing sound when activated **Capacitor**-an electrical component, used to store a charge temporarily, consisting of two conducting surfaces separated by a nonconductor dielectric
 * Wires**-a strand of metal, usually copper, that is encased in plastic or another insulating material and is used to carry an electric current

- Explanation of difficulties encountered while creating the circuit: This circuit was very difficult to construct. There were many different pieces and wires in the circuit. You had to be very exact to create this circuit. If there was a wire in the wrong hole, the whole circuit might not work. We had to work slowly and carefully and go over the circuits in order for it to work.

=__Name of Circuit: 4049 Hex Inverter__=

- Function of the circuit: The function of the circuit is to show how the logic inverter works, and to make the four LED's on the top of the breadboard flash.

- Components used in the circuit (listing with basic definitions):

The components used in the circuit are:

**Integrated circuit**- An integrated circuit is a tiny complex of electronic components contained on a thin chip or wafer of semiconducting material. **Resistors**- Resistors are components of an electrical circuit that have resistance and are used to control the flow of electric current. **Capacitor**- A capacitor is an electrical component, used to store a charge temporarily. It consists of two conducting surfaces separated by a nonconductor dielectric.
 * Wires**- Wires are strands of metal, usually copper, that are encased in plastic or another insulating material. They are used to carry an electric current.
 * LED (4)-** (Light Emitting Diode) LEDs light up on the breadboard used when a button is pushed if the circuit is constructed correctly. The LEDs were red in the circuit created.

- Explanation of difficulties encountered while creating the circuit:

At first, it was not apparent that there were LEDs on the actual breadboard, and that the LEDs did not have to be actually attached to the breadboard. Once that realization was achieved, the circuit was created quickly and easily.
