Light Up Music Box

For this project we had to write a program to light up LED lights. We used jumper wires, resistors, an Arduino board, a breadboard, LED light bulbs, a cable cord, and our computers to write the program. We wired the breadboard to the Arduino. We put the jumper wires in the right holes for negative and positive and put the cord in the computer, . went into the Arduino IDE wrote the program, uploaded it and it lit the LEDs. I learned about negative and positive, the positive is longer then the negative. I learned that ground it very important because the light will not connect to the wires to light up. I am proud of myself doing this and not getting hurt. I would have done nothing differently if I had to do it again. I like this project because I knew what all the wires were for and how to light my LED.

For this project we made a LED light up that had 3 LEDs in one. We used 3 resistors, 4 wires that were in front of the 3 resistors so they can get power from the Arduino board to the breadboard. Lastly the cable from the Arduino board to the computer. There are 3 legs on the LED that connect to the resistors and they connect to the wires that connect to the pins on the Arduino board. There is one more leg from the LED which was the the longest leg that connects to ground. Then we used the cable to the computer and ran the code we created in the app, Arduino IDE, to show the colors Red, Green, and Blue. After we got the primary colors Red, Green, and Blue, we made the secondary colors which are Red and Green which makes Yellow. Green and Blue which makes Cyan. Blue and Red which makes Magenta. We used analogWrite and not digitalWrite because analogWrite lets you choose the color between 0 to 255, but digitalWrite only will let you do HIGH and LOW. I learned the primary colors of light and the secondary colors of light and that they are not the same as the pigment primary colors. I was proud of myself making the LED light up colors without having just a single color LED. I was excited about this activity because we could see the primary colors and secondary colors of light for the first time.

For this project I created music by using 1. a buzzer, 2. Three wires, 3. a USB cable, 4. a breadboard, 5. an Arduino board, and 6. the Arduino IDE app. 1 used the app to write the code for the song to be created. Our song I made was the first three notes of Three Blind Mice played twice. My goal was to make a song that I like. I used variables to indicate the frequency for the notes and the length of quarter notes. A variable is a container that holds value one at a time it can hold numbers, text, whole number, and maybe your name. What I learned is that there are resistors in the buzzer that I used for this project. I also learned that the frequencies of notes are different. I am proud of making music without a real instruments.

For this project I made a music box with an LED light show. I wanted to make my own song because I had a tune in my head for this project. It is called Random Clouds. At first I used a buzzer that gave sound, and to get the notes for my song I used a website called Piano Player to figure out the frequency of my notes. First what I did when I had to program my song was I figured out what notes I wanted to use and then found their frequency. Then I wrote my program in the Arduino IDE. I used 5 LEDs, 5 wires to coordinate the colors with the LEDs. Then 2 extra wires that connected to the power and ground on the Arduino. I also used resistors that I cut short to make them easier to deal with, I chose rainbow for my LED colors because it made it easier to coordinate with the song. After the program was finished, I wired the Arduino Board. I decorated my board with cotton balls because it looked like clouds and a googley eye to represent that God is watching us all. I was happy to make the project because it was like making a light show. I learned that it is harder to make a song than it looks because each note has a lot of code. I was proud of the song I wrote. :p

Afterwards I added a button. This helped because when you plug it in the music won't start without you pushing the button (very helpful). The video you see does not show the button because I did it after we made the video, SORRY FAM !!!! Also the button was harder because it is a INPUT and not a OUTPUT it sends information to the Arduino and you have to check for that in the code. My problems was that the resistor was not connecting with the wires under the breadboard.
