This is where I will publish my projects:

Project number 1: LED Lights sequence.

What you will need: download arduino software, 

Windows

Mac OS X

Linux

Portable IDE (Windows and Linux)                                 

Once you have downloaded the matching software, buy a Arduino Uno board,

Arduino Uno Rev3 SMD 

This link above will take you to the arduino website where you can buy more materials. For this project you will need:

Arduino Uno

Bread board

Jumper wires

Led Lights

USB Cable(To compile code)
 
3 220 OHM resisters
                                         
Starting off the project, connect the ground pin(GND) to the negative rail of the breadboard. then connect all of the resistors one leg on the negative rail and the other somewhere in the middle of the bread board. Before inserting the LED’s note that the longer pin is the positive side, and the shorter pin is the negative  side of the LED. Connect the negative pin of the LED to the other side of of the 220 OHM resistors that is not connected to the GND. Do the same for all 3 LED’s.

Then use connect jumper wires to connect numbers 13(Right side LED),12(LED in the center), and 11(Left side LED) to the positive pin of the LED. code:int LED1 = 13;
int LED2 = 12;
int LED3 = 11;

CODE:
void setup() {
pinMode(LED1, OUTPUT);
pinMode(LED2, OUTPUT);
pinMode(LED3, OUTPUT);
}
void loop() {
digitalWrite(LED1, HIGH); // turn on LED1
delay(200); // wait for 200ms
digitalWrite(LED2, HIGH); // turn on LED2
delay(200); // wait for 200ms
digitalWrite(LED3, HIGH); // turn on LED3
delay(200); // wait for 200ms
digitalWrite(LED1, LOW); // turn off LED1
delay(300); // wait for 300ms
digitalWrite(LED2, LOW); // turn off LED2
delay(300); // wait for 300ms
digitalWrite(LED3, LOW); // turn off LED3
delay(300); // wait for 300ms before running program all over again
}

 

 

Project number 2: The motion detector.   

what you will need:

1- ARDUINO

2-HC-SR04 Ultrasonic Sensor

3-Buzzer

4-a few jumper wires

5- a breadboard 

For this project, i have schematics

Image result for arduino ultrasonic sensor motion detection schematics

 

 

 

 

 

 

code:

const int trigPin = 9;
const int echoPin = 10;
const int buzzer = 11;
const int ledPin = 13;

// defines variables
long duration;
int distance;
int safetyDistance;

void setup() {
pinMode(trigPin, OUTPUT); // Sets the trigPin as an Output
pinMode(echoPin, INPUT); // Sets the echoPin as an Input
pinMode(buzzer, OUTPUT);
pinMode(ledPin, OUTPUT);
Serial.begin(9600); // Starts the serial communication
}

void loop() {
// Clears the trigPin
digitalWrite(trigPin, LOW);
delayMicroseconds(2);

// Sets the trigPin on HIGH state for 10 micro seconds
digitalWrite(trigPin, HIGH);
delayMicroseconds(10);
digitalWrite(trigPin, LOW);

// Reads the echoPin, returns the sound wave travel time in microseconds
duration = pulseIn(echoPin, HIGH);

// Calculating the distance
distance= duration*0.034/2;

safetyDistance = distance;
if (safetyDistance <= 5){
digitalWrite(buzzer, HIGH);
digitalWrite(ledPin, HIGH);
}
else{
digitalWrite(buzzer, LOW);
digitalWrite(ledPin, LOW);
}

// Prints the distance on the Serial Monitor
Serial.print(“Distance: “);
Serial.println(distance);
}

alright we have a different project today. We are going to be working on a python animation that is called pong. it is a game that consist of 2 players moving a paddle and hitting the ball back and forth.
 
here are the links to download  the latest versions of python
 
 

Python 3.7.3

Python 3.4.10

Python 3.5.7

Now to start this off you have to open the python page. ( i would consider that you go back to the page were i show you the main functions of python)  then use this code.

 

# By @TokyoEdTech

wn = turtle.Screen()
wn.title("Pong")
wn.bgcolor("black")

paddle_a.shapesize(stretch_wid=5,stretch_len=1)
paddle_a.penup()
paddle_a.goto(-350, 0)

# Paddle B
paddle_b = turtle.Turtle()
paddle_b.speed(0)
paddle_b.shape("square")
paddle_b.color("white")
paddle_b.shapesize(stretch_wid=5,stretch_len=1)
paddle_b.penup()
paddle_b.goto(350, 0)

# Ball

        ball.dy *= -1
        os.system("afplay bounce.wav&")

        pen.clear()
        pen.write("Player A: {}  Player B: {}".format(score_a, score_b), align="center", font=("Courier", 24, "normal"))

        ball.goto(0, 0)
        ball.dx *= -1

    # Paddle and ball collisions
    if ball.xcor() < -340 and ball.ycor() < paddle_a.ycor() + 50 and ball.ycor() > paddle_a.ycor() - 50:
        ball.dx *= -1 
        os.system("afplay bounce.wav&")
    
    elif ball.xcor() > 340 and ball.ycor() < paddle_b.ycor() + 50 and ball.ycor() > paddle_b.ycor() - 50:
        ball.dx *= -1
        os.system("afplay bounce.wav&")

after this use the turtle module to run this exact code. you can add your own features, for example you can change the background color to a more noticeable color, like red or blue. you can also change the way the game works like you can to two points every time the ball crosses the line. Enjoy!





Alright, today were gonna do something new!
everyone has to has to have wanted to 3d print something in their life. i mean, its the coolest thing ever!

Lets cut to the chase, first you need to download the "Inventor" file(your computer has to have a LOT of storage.)


i also made some models. here is a model

Model rockets. This is a more recent project made in my engineering 7 class. the rocket consist of many parts, listed below.

igniter               solid fuel engine        engine mount           fins          launch lug          rocket body              shock cord          nose cone     parachute     shroud lines

these are the assembly steps (written by me):

Step 1: Making the body. The body is literally the rocket minus a few features. First, you have to measure the thickness of the cylinder with a plastic tube,then when you find the right roll you glue it shut. After that cover the roll with a colored paper of your choice.

Step 2: The nose cone and wings: wings, first you have to copy down the same type of shape i the book (don’t forget to leave the little hole in it) then copy it down on the more plastic like paper in a pattern and neat enough so that you can fit it 3 times. Cut this out and use the stand to glue the wings on, now your rocket can soar. Second, the nose cone attachment. Three things, the actual nose cone, a string, and a small piece of paper. First you tie two knots on the string to the nose cone. Once you have done that do 3 glued folds on the bottom of the string to the small piece of paper, then you use your gluedobber to put it inside of the cylinder. 

Step 3: paint,engine,launch lug, and parachute. I am going to try to put this all together. Paint, well that one is up to you. The engine is put inside the engine holder that keeps it in place with a hole left out so the wires can connect to it. The launch lug is tapped not to low into the wings but half the length. And the parachute you have to cut through the holes, tie string in to them (2-6 holes), then tie the parachute on to the nose cone.

Congrats, you have completed your rocket

 

and this is how the launch goes (also written by me):

A rocket consist of 10 parts (or at least in this case) like the body, the nose cone, the engine,etc.The way a rocket works is multiple parts. First, the engine is attached to alligator wires that consist of two voltages one higher than the other. The rocket is put on a pole through the launch lug to make sure the takeoff is more vertical. After that when the rocket is ready to launch one of the other sides of the alligator wires (the stronger one) is put on a coil wire, when contact made………..BOOM, your rocket has successfully left the earth’s ground.

you can reuse the engine, most recommended engine is the estes fuel engine.

 This is another project i made in my engineering class. The thing i made is a practice letter. i made this out of the material of crafting wood. I chose the letter S, which mainly uses the scroll saw but i will explain all of the machines.

Band saw: The band saw is made mainly to cut strait lines. The blade is heavy in a upward position, but if you curve to much it would break. There is a way to make curved cuts, made relief cuts first. Relief cuts are small lines made to allow the saw to make a different approach on the on the block.

Scroll saw: The scroll saw, to me is much more effective than the band saw. It can make swift, and smooth cuts to the block giving it the ability to cut curves. I used this muuch more because i made the letter S, as you would know it is really curvy.
