LED Flasher Circuit
- Function of the circuit:

When all of the wires are correct, the LED flashes on and off.

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

__Circuit Board__ - A place where circuits are built. __Integrated Circuit (555)__ - A tiny circuit in a plastic package with external pins. __LED__ - A light emitting diode which emits colored light (green in this circuit). __Capacitor__ - Capacitors store an electric charge and block the continuous current. In this circuit, the capacitor was 10 UF. __3 Resistors__ - Resistors resist the current to protect the LED from blowing out. There were three resistors in this circuit. R1 was 4.7K and its color combination was yellow-violet-red. R2 was 10K and its color combination was brown-black-orange. R3 was 1K and its color combination was brown-black-red. __3 white wires__ - Wires provide a pathway for electricity to flow. __1 red wires__ - Wires provide a pathway for electricity to flow.

- Explanation of difficulties encountered while creating the circuit:

It was hard to maneuver the wires to get them around the others into the correct holes. When doing so, some of the wires got pulled out. Also, it was hard to match the number to the letter because being exact is neccesary.

=555 Black Box Circuit=

- Function of the circuit:

When all of the wires are correct, the buzzer buzzes.

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

__Circuit Board__ - A place where circuits are built. __Integrated Circuit (555)__ - A tiny circuit in a plastic package with external pins. __3 resistors__ - Resistors resist the current, causing less electrical power throughout the circuit. Three resistors were used. R1 was 10K and its color combination was brown-black-orange. R2 was 1K and its color combination was brown-black-red. R3 was 100K and its color combination was brown-black-brown. __Capacitor__ - Capacitors store an electric charge and block continuous current. The capacitor used in this circuit was 0.1 UF. __3 white wires__ - Wires provide a pathway for electricity to flow. __4 blue wires__ - Wires provide a pathway for electricity to flow. __4 red wires__ - Wires provide a pathway for electricity to flow.

- Explanation of difficulties encountered while creating the circuit:

The main difficulty was putting the wires into the springs, but even so, the circuit was created on the first try. Also, putting the capacitor in was confusing, as it was not known if it was directional.

= = =Set-Reset Latch=

- Function of the circuit:

When all of the wires are correct, both of the LEDs light up.

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

__Circuit Board__ - A place where circuits are built. __Integrated Circuit (4001)__ - A tiny circuit in a plastic package with external pins. __4 resistors__ - Resistors resist the current, causing less electrical power throughout the circuit. There were four resistors used. R1 and R2 were 10K and their color combination was brown-black-orange. R3 and R4 were 1K and their color combination was brown-black-red. __2 LEDs__ - A light emitting diode which emits colored light (green and red in this circuit). __9 white wires__ - Wires provide a pathway for electricity to flow. __2 red wires__ - Wires provide a pathway for electricity to flow. __1 blue wire__ - Wires provide a pathway for electricity to flow.

- Explanation of difficulties encountered while creating the circuit:

The green LED did not work on the first try, but when it was flipped around it lit up. Therefore, the positive and negative sides must have been mixed up. Even so, the red LED never did begin to work.
