Arduino

Pressing the buttons causes the LED to light up, holding down the buttons causes the LED to stay lit up until released.

In the original code, the photoresistor senses a decrease in light, the code then causes the LED to recieve more power, making it brighter as the room gets darker.

In the modified code,  the LED turns completely dark in the prescence of light and fully lights up in the prescence of shade.

The temperature sensor detects the temperature of the room and relays that information to the computer through the Arduino board. When a temperature below 72.1 degrees is detected, the Arduino board powers the LED for one second.

The servo motor moves the servo hrons through a series of spinning gears housed in the blue, plastic box. The code intructs the servo to rotate with several variables accounting for its speed and rotation.

The piezo speaker works by rapidly vibrating a material at different frequencies to produce different tones. The original code plays Rick Astley's "Never Gonna Give You Up", but the code I modified plays a new sequence of notes.

The DC Motor works by converting electrical energy into mechanical energy. The code causes the motor to accelerate from speeds 0-255. The code allows for the duration of the spin and the speeds to be changed.

The relay (black box), is an electromagnetic switch that work by creating a magnetic field, controling a switch the directs power to one of the two LEDs. The code fires the relay every second to light up one of the two LEDs.

The Integrated Circiut is a package of transistors and other electrical components that regulate the current allowing the board to power multiple LEDs at once.

The marquee pattern works by firing the corresponding LEDs on both sides of the bread board in a descending order.

The ping pong pattern works by firing the LEDs in an order and then reversing that same order, creating a "ping pong" effect.

The random LED pattern works by creating a RNG element, randomly choosing which LED to power.
