Business card design and mockup
Today I just want to show you a quick tip about designing a business card mockup so you can easily show it to your customer about the way it look in real life and they can feel that it is modern and like it. I used Adobe Photoshop to do this so I would recommended you to use Adobe Photoshop any version from CS2 up to CC.
For this tutorial section I used Adobe Photoshop CS5 so it works nice and fast enough for my computer.
So get in to the tutorial now:

Arduino Chapter 1 - LED fade
How it work
This example will guide you to make a fade on LED using Arduino IDE. As the previous lesson you saw how you can bright an LED up and turn it back off and now I am going to show you about you can make it fade ON and fade OFF.
Requirements
- Arduino board
- Breadboard
- hook-up wires
- LED 3v
- 220 Ohms or 250 Ohms resister
Code
int led = 9; // the PWM pin the LED is attached to
int brightness = 0; // how bright the LED is
int fadeAmount = 5; // how many points to fade the LED by
// the setup routine runs once when you press reset:
void setup() {
// declare pin 9 to be an output:
pinMode(led, OUTPUT);
}
// the loop routine runs over and over again forever:
void loop() {
// set the brightness of pin 9:
analogWrite(led, brightness);
// change the brightness for next time through the loop:
brightness = brightness + fadeAmount;
// reverse the direction of the fading at the ends of the fade:
if (brightness == 0 || brightness == 255) {
fadeAmount = -fadeAmount ;
}
// wait for 30 milliseconds to see the dimming effect
delay(30);
}

Photoresistor
How it works
This sensor can be called light-dependent resistor, LDR, or photocell is a light-controlled variable resistor. The resistance of a photoresistor decreases with increasing incident light intensity.

Circuit:
Reflective Optical Sensor TCTR5000
How it works
This sensor is reflective with infrared light and it contained emitter and phototransistor in a leaded package. This sensor will send the signal HIGH(1024) when it sees light color or reflection and it will produce down to LOW(0) when it sees darkest. So we can use that range for many different tasks depending on the project.

Arduino Chapter 1 - language structure - setup() and loop()
In Arduino they use their programming language which is using OOP but they have customize some keywords or namespaces.
Today I am going to show you about the base structure of Arduino such as Setup() and Loop()
Example
int btnPin = 3;
void setup()
{
Serial.begin(9600);
pinMode(btnPin, INPUT);
}
void loop()
{
// ...
}
Note
Serial.begin() //used to tell the processing speed be tween Arduino and computer
pinMode(pin,status) //used to assign status to a pin
Example
void loop()
{
if (digitalRead(buttonPin) == HIGH)
Serial.write('HIGH');
else
Serial.write('LOW');
delay(1000);
}
Note
digitalRead() //used to read digital signal from a pin
Serial.write() //used to show the information back to the computer through Arduino
Today I am going to show you about the base structure of Arduino such as Setup() and Loop()
setup()This function is called when a sketch starts. Use it to initialize variables, pin modes, start using libraries, etc. The setup function will only run once, after each powerup or reset of the Arduino board.
Example
int btnPin = 3;
void setup()
{
Serial.begin(9600);
pinMode(btnPin, INPUT);
}
void loop()
{
// ...
}
Note
Serial.begin() //used to tell the processing speed be tween Arduino and computer
pinMode(pin,status) //used to assign status to a pin
loop()This function is used to loop the action repeatedly again and again.
Example
void loop()
{
if (digitalRead(buttonPin) == HIGH)
Serial.write('HIGH');
else
Serial.write('LOW');
delay(1000);
}
Note
digitalRead() //used to read digital signal from a pin
Serial.write() //used to show the information back to the computer through Arduino

Vongchann Electronic Arduino with OLED Display Screen
Wooo. OLED.
Do you know what is OLED stand for? it stands for Organic Light Emitting Diots. Today I am gonna show you how this thing will work with Arduino and You will also see that what can OLED do or show on its screen.
I am using 128x64 pixels OLED so it is quite small but it works well.This article just want to show you about how I test it, if you want to see more about the tutorial of the process and how you can work with it step by step, then just calm down and follow or subscribe my channel.
Before you can start working with this OLED and Arduino the main thing you have to know is the serial and ID of it as the OLED that I am using is U8GLIB_SSD1306_128X64 u8g(U8G_I2C_OPT_NONE|U8G_I2C_OPT_DEV_0);
Now. let's see my video about using Arduino with OLED Display Screen
Vongchann Electronic - Arduino with HC SR04 Sensor test
Today I have another sensor called HC SR04. This sensor used to tell the distance between object that is right in front of it. This sensor has two special parts that we should never forget such as:
Trigger: is the part which send out the sound to hit any object in front of itAccording to these two parts this sensor can help use to find the distance between object that is in front of it.
Echo: is the part which wait for the sound to come back and calculate the waiting time
In fact, Want to see how it works? Watch the video below then you will see it.
Vongchann Electronic - Arduino And Remote Control Test
Now it is time for you guys to see my experiment with Arduino and other electronic component and now I choose IR Receiver to make a remote control with LEDs.
When I press the button on the remote control it will tell the LED which I assigned to turn on then I press another button it do the same way and I can also turn them off with the remote control as well. The interesting thing about this experiment is I will change various of remote control so you can see that we can use Arduino to manage and control those components.Check my video below you will see how it works.
Vongchann Electronic - Electronic Circuit
After we have known and understand how Ohm Law works; now I would like to bring you guys back to see about electronic circuit which we have already learned at high school.
In this article I just want you guys to see the differences between two electronic circuit such as Serial and Parallel.
Serial: The circuit will focus on the voltage of each electronic component and they will continue adding the voltage of all the components to the circuit.See my video you will see and understand more about these two types to circuit:
Parallel: The circuit will focus on the current that flow a long; it doesn't care about huge voltage but it cares about the current that it would be able to handle the electronic components.
Vongchann Electronic - Ohm Law
I want to have a bit of review about Ohm Law before we jump in to the lesson about electronic, it is really useful in physic theory that Ohm Law is used to describe about the potential difference (voltage) across an ideal conductor is proportional to the current through it. The constant of proportionality is called the "resistance", R.Ohm's Law is given by:
V = I R where V is the potential difference between two points which include a resistance R.As this is the matter for all learners I would like you guys to see my video about Ohm Law as shown below:
