 Basically, LEDs are just tiny light bulbs that fit easily into an electrical circuit. But unlike incandescent bulbs, they don't have filaments that burn out, they use less electricity, and they don't get especially hot. They're illuminated solely by the movement of electrons in a semiconductor material, and they last just as long as a standard transistor. The life span of an LED surpasses the short life of an incandescent bulb by thousands of hours. Because of these advantages, tiny LEDs are one of the most popular technologies used to light LCD TVs.

-=====PROJECT 4=====
+=====THE SHY PI=====
 ====DESCRIPTION====
+Basically my fso1 was a distance sensor with a buzzer and light system. As you get closer the buzzer gets higher pitched If distance>30cm the green light was on and the buzzer was off. If distance<30cm the yellow light turned on and the green light turned off. If distance<10cm the red light turned on and the yellow light turned off. However this is a very shy pi so whenever something gets too close the pi gets scared and turns off.

-=====PROJECT 5=====
+=====Stopwatch=====
 ====DESCRIPTION====
+It uses the last configuration of the breadboard for fso1 except with 2 buttons added. These buttons are used as a 'reset' and 'pause' button for the stopwatch. It iterates a counter every clock cycle to count its lowest value of time which is by far the least efficient way to accomplish the functionality of a stopwatch. The stopwatch only displays hours and minutes with seconds displayed on the six LEDs in binary from 0-59. This is not useful.
 ====DEMONSTRATION====
+Starting the stopwatch is as easy as pressing the 'start/stop' button, on the left. This initially starts the LEDs counting up to 1 minute in the least helpful way. You can also reset the counter without stopping it if you want, but it doesn't matter anyway because displaying to a screen slows the program down so much that one second is like 150% longer.

-=====PROJECT 7=====
+=====4-Digit 7-Segment LED Timer=====
 ====DESCRIPTION====
+This circuit uses the 4 digit LED display and the clock coding feature to serve as an active counter that begins at 0 and counts up to 9999. This timer is different because I have added a button that when pressed will halt the counting at the current number. Then, when the button is pressed again, the counting will resume at the same number, until the button is pressed again the process will repeat.

-=====PROJECT 8=====
+=====Thrust Vector Control (TVC) Mount=====
 ====DESCRIPTION====
+In this project, I used the Adafruit Gy-521 and two Servos. These electronics were used for the goal of making sure that a model rocket is properly orientated during its flight and guaranteeing a nominal trajectory for it.
-====DEMONSTRATION====
+The GY-521 is an accelerometer/gyroscope that will detect a change in the orientation of the craft as it is flying and will send a signal to the Arduino that the orientation of the craft is off. This will then send a signal to the servos that the orientation is off and needs to be fixed. Determining how much of a correction needs to be made is determined by a Proportional Integral Derivative (PID). A device that will automatically apply an accurate and responsive correction to a control function. This basically determines how fast/ intensely the servo responds to an error in the orientation of the device.
