--My Learning Dashboard--

Today during my conceptual physics class, my teacher introduced the Arduino developing kit, and we started working on it. I had a little experience of coding so it was not hard for me. Therefore, I created this Arduino project that can control the LED on the broad to spell my name using Morse code. This is the code that I wrote >>> int LED = 13; int dot = 300; int dash = dot * 3; int elemPause = dot; int charPause = dot * 3; int wordPause = dot * 7; char fName[] = "allen"; char lName[] = "lin"; void setup() {   pinMode(LED, OUTPUT); } void MorseDot() {   digitalWrite(LED, HIGH);     delay(dot); } void MorseDash() {   digitalWrite(LED, HIGH);     delay(dash); } void MorseElemPause() {   digitalWrite(LED, LOW);    delay(elemPause); } void MorseCharPause() {   digitalWrite(LED, LOW);   delay(charPause); } void MorseWordPause() {   digitalWrite(LED, LOW);     delay(wordPause); } void longP...

This beat is basically using the same chord but different rhythms that creates a rap style. It is a simple song and the melody is played with an electric guitar. Enjoy the music:)

Today when I was editing my videos for MetaScience.Lab , I realized some hot keys for Sony Vegas. Here are the followings: Shift + mouse wheel = moving horizontally Ctrl + mouse wheel = moving vertically mouse wheel = zoom in & zoom out Shift + long press = select multiple clips Ctrl + long press = copy and move selected clips I think it is pretty useful and if you want to check out the video please subscribe my channel. I offer lots of science videos, DIY tutorials, presentations, etc, on that channel. I am now trying a different way to construct my videos. Emjoy:)

I learned that the structure of android developing is like a nesting style, which looks very much like a hamburger. The most outer code line is the syntax, which are mostly closed with brackets, like: <LinearLayout> ... </LinearLayout> The second most outer code line is the type of the View group, like: <TextView .../> Then it comes the general coding section which has all the settings, like: android.text="Hello World!" android.textSize="40sp" All together will become like: <LinearLayout> <TextView     android.text="Hello World!"     android.textSize="40sp"/> </LinearLayout> Doesn't it look like a hamburger?

Today I made this rap song that has a kind of creepy, mystery, and sketchy sound. I think this is one of the coolest song I've ever made so far. It just sounds really cool. Because I really like the sound of this song, so I'm going to share with you guys about the presets I've used in this song. 1. Chord: A preset "ATM Night Terrors FG" in the  synth special plugin "Sakura". 2. Vocal: A preset "VOX Choir NUC" in the  synth special plugin "Morphine". 3. Melody: A preset "Clockwork" in the synth special plugin "Ogun". 4. Bass: A  preset  "Cube" in the  synth special plugin  "Ogun".   Like the song and follow me:)) (If you are interested in buying this song, please contact me:  a20011106a@outlook.com )

Today I went to UC Berkeley and I went to the student bookstore which has a section full of QuickStudy . So basically I bought a Spanish guide, a French Grammar guide, an Arabic guide, and a Physics guide. Here is a preview of the Arabic guide: I think the alphabet chart is very useful because it is not only an alphabet list but it lists the alphabets in different forms. In Arabic, alphabets change their forms according to their position and this chart has a full list of Isolated, Initial, Medial, and Final form, combine with the pronunciation guide besides it. It makes it a lot more simple to study and memorize the writing and the pronunciation of the alphabets.
