LED Flasher
- Function of the circuit: The function of the LED circuit was to make a LED flash.

- Components used in the circuit (listing with basic definitions): The components used in the circuit were LED, electrical wires, resistors, capacitors, and 555 integrated circuit. An LED is a light emitting diode. Electrical wires are used to connect the different components in a circuit. Resistors in a circuit are used for resisting the flow of electricity. On the other hand capacitors are used to smooth fluctuating current and used to store electrical power. The integrated circuit are microscopic electronic circuits that are used to recieve and send out data in the circuit.

- Explanation of difficulties encountered while creating the circuit: There were a few difficulties while creating the LED flasher. The major difficulty was telling which side was the anode and cathode of the LED and the capacitor. A minor problem that occured was putting the components in the right places on the breadboard.

555 "Black Box"
- Function of the circuit: The function of this circuit was to make the buzzer buzz.

- Components used in the circuit (listing with basic definitions): The components used in the circuit were electrical wires, resistors, capacitors, buzzer, and 555 integrated circuit. Electrical wires are used to connect the different components in a circuit. Resistors in a circuit are used are to resist the flow of electricity. On the other hand capacitors are used to smooth fluctuating current and to store electrical power. The integrated circuit are microscopic electronic circuits. The buzzer is an electronic device that produces high frequency sound.

- Explanation of difficulties encountered while creating the circuit: The difficulties in putting this circuit together was trying to find the right places for all the wires and components.

A Frequency Synthesizer- page 88
- Function of the circuit: The function of the Frequency Synthesizer is to make a high frequency noise.

- Components used in the circuit (listing with basic definitions): There were quite a few new components used in this circuit. The electrical wires, integrated circuits, and capacitors were used as in the previous circuits. The new components were the potentiometers, LED's (light emitting diode), and the speaker. An LED is a light emitting diode. Electrical wires are used to connect the different components in a circuit. The capacitors are used to smooth fluctuating current and used to store electrical power. The integrated circuit are microscopic electronic circuits. A potentiometer is a manually adjustable resistor. The speaker is used to make the noise be heard. A transformer is usually used to connect a speaker to the power source.

- Explanation of difficulties encountered while creating the circuit: The biggest difficulty was there was so many wires it was hard to get them in their right places because they went around and between different wires.
