Name of Circuit
- Function of the circuit: - Components used in the circuit (listing with basic definitions): - Explanation of difficulties encountered while creating the circuit: - Multimedia (Images, Interviews, Videos- make sure to title and number them)

LED Flasher
- Function of the circuit: Causes the breadboard to emit a tone.

- Components used in the circuit (listing with basic definitions): Wires- A string of metal that is insulated with plastic. They also conduct and carry electricity. Resistor- A device that resists the flow of electricity Capacitor- A device that stores electricity in between two conductors in an electric field. Integrated circuit- A microscopic electronic circuit that can consist of millions of diodes, transistors, and other devices. LED- A p-n diode where electricity moves from p to n in order to emit light.

- Explanation of difficulties encountered while creating the circuit: Some of the difficulties that were encountered were the exact placing of the wires in the Breadboard and putting the devices in the right direction. The holes of the breadboard are small, so it was hard to connect the wires into the exact hole. Determining where the cathode and anode of a device is placed in the right direction was also a major difficulty.

555 "Black Box"
- Function of the circuit: Causes the black box to emit a tone

- Components used in the circuit (listing with basic definitions): Wires- A string of metal that is insulated with plastic. They also conduct and carry electricity.. Resistor- A device that resists the flow of electricity Capacitor- A device that stores electricity in between two conductors in an electric field. Integrated circuit- A microscopic electronic circuit that can consist of millions of diodes, transistors, and other devices. Speaker- A device that converts electric signals into sound. Buzzer- A signaling device that emits a tone when a button is pressed or a preset time is lapsed.

- Explanation of difficulties encountered while creating the circuit: Building this circuit had some difficulties. One of them was choosing the correct pieces, especially the resistors. Another difficulty was plugging the wires in. Sometimes, the wires were barely long enough so we had to bend the wires to the limit.

4001 Quad NOR Gate
- Function of the circuit: Causes the breadboard to emit a tone that can be controlled by a photoresistor.

- Components used in the circuit (listing with basic definitions): Capacitor- A device that stores electricity in between two conductors in an electric field. Integrated circuit- A microscopic electronic circuit that can consist of millions of diodes, transistors, and other devices. Wires- A string of metal that is insulated with plastic. They also conduct and carry electricity. Photoresistor- A device that sense light and darkness. Speaker- A device that converts electric signals into sound.

- Explanation of difficulties encountered while creating the circuit: The main difficulty that was encountered was the direction of the integrated circuit. It took a while to remember the importance of the direction. The other difficulty is pushing the wires into the holes of the breadboard.
