LED Flasher Circuit
- Function of the circuit:

The function of the circuit was to make the LED light up and flash. Also, if a few wires were moved around the circuit could serve as a noise-maker as well.

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

Some components were the LED, red wires, white wires, resistor 1, resistor 2, resistor 3, the 555 IC, and the breadboard.
 * An LED is a light emitting diode, basically tiny lightbulbs that fit in electrical circuits
 * A breadboard is a device that is usually used to build electronic circuits, located in the center of the circuit board.
 * A wire is a string of metal that is used to carry electricity from one place to another, and the different wires are recognizable by the color of rubber over them, thus making the wires "white" or "blue" or "red."
 * A 555 IC is commonly called the Timer IC. It is an integrated chip that includes 25 transistors, 2 diodes, and 16 resistors. There are different pieces that look like this, so you have to look at the small writing to determine which one it is.
 * A resistor is an electrical component that conflicts with electrical current, as explained by Ohms law.

- Explanation of difficulties encountered while creating the circuit:
 * The 555 IC had to be the right piece, because if the similar pices were used, the whole circuit will be messed up.
 * The holes in the breadboard are so small that it is hard to place the components in the correct place.
 * If there was one problem the circuit would not work, therefore it took a few days to complete a circuit.
 * If a component is in the wrong place or placed upside down, in some cases it might become hot.
 * Troubleshooting took a while.
 * Sometimes the batteries might not work and it would take a while to find out that the problem was the batteries.

555 "Black Box" Circuit
- Function of the circuit:

The function of the 555 "Black Box" circuit was to make the buzzer make noise.

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

Some components were the 555 IC, the breadboard, white wires, red wires, blue wires, resistor 1, resistor 2, resistor 3,, and the capacitor.
 * A 555 IC is commonly called the Timer IC. It is an integrated chip that includes 25 transistors, 2 diodes, and 16 resistors.
 * A breadboard is a device that is usually used to build electronic circuits.
 * A wire is a string of metal that is used to carry electricity from one place to another.
 * A resistor is an electrical component that conflicts with electrical current because of Ohms law.
 * A capacitor is a electronic device that stores electricity in electric fields between conductors.

- Explanation of difficulties encountered while creating the circuit:

Everything correct except the 555 was upside down. This caused a problem because the whole circuit wouldn't work if one thing was placed incorrectly. A few wires were misplaced, and this also caused problems with the final outcome of our circuit.

The Incredible Music Machine
- Function of the circuit:

The function of the music machine is to make sounds.

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

The components used were red wires, blue wires, white wires, C1, C2, R2, R3, R4, and the 555

- Explanation of difficulties encountered while creating the circuit:

Some difficulties encountered were having all the wires and other components in the exact place or it won't work. One must double check the wiring if the circuit doesn't work.
