LED and Potentiometer Using Arduino

Control the blinking rate of the light-emitting diode(LED) by using a potentiometer. So, what is a potentiometer? 

The potentiometer is an instrument, it has three terminal variable resistors. It manually controls the flow of electric current. Two terminal is connected to the resistive element and the third is connected to the adjustment wiper. which means that the rotation of the of the wiper may determine the output voltage.

Potentiometer

Required.
1 x LED color as you like.
Arduino board
Wire,
Breadboard
Potentiometer
Resistor 330Ω

1. Connect to the breadboard

Connect According to the diagram as I have shown you. In the above figure, the black wire is connected to the GND pin and the red wire is connected to the 5V pin above the GND pin in the Arduino board. Connect LED as shown here. Now place your potentiometer on the breadboard, as shown in the diagram. the potentiometer has 3 terminal. The first terminal (blue & black wire) is connected to the negative terminal, the last terminal (orange & red wire) is connected to the 5v. The green wire is taken from the middle terminal to A0 (analog) in the Arduino board.  

2. Open Arduino IDE software 

 Type the code: 

int sensorPin = 0;

int ledPin = 13;

void setup()

{

  pinMode(ledPin, OUTPUT);

}

void loop()

{

int sensorValue;

  sensorValue = analogRead(sensorPin );

  digitalWrite(ledPin , HIGH);                                   

  delay(sensorValue);                                                  

  digitalWrite(ledPin, LOW);                                 

  delay(sensorValue);                                                  

}

3. Verify and Upload code to Arduino Board

Once the code is Verified and uploaded to your Arduino Board, then you notice rapid blink of LED for one second. Do not worry, it is an indication that your code is successfully uploaded.

DONE

Start to rotate the mover of the potentiometer in order to get the result.

if it is not working let me know down in the comment.

Blinking Of LED Using Arduino

As we know that light-emitting diode(LED) is a semiconductor device that produces light from electricity. They can produce many different colors. so in this experiment, we are going to blink LED.

Required.
1 x LED color as you like.
Arduino board
Wire,
Breadboard
Resistor 330Ω

Please make sure the connection, because it has a positive and negative terminal  Negative terminal will always connect to ground (GND) and the positive terminal will always connect to the required pin (13,12,9....) as shown. 

1. Connect to the breadboard

Connect According to the diagram as I have shown you. In the above figure, the black wire is connected to GND and the red wire is connected to the 5V above the GND pin in the Arduino board. Place the LED as shown in the figure, the negative terminal is connected with one end of the resistor and the second end of the resistor is connected to the negative terminal(fig). We place a resistor in order to avoid damage for LED if more current flows. The green wire is connected to pin 12, once the circuit is complete. Connect your Arduino board to your computer with the help of USB cable.

2. Open Arduino IDE software 

 Type the code: 

void setup()

{

  pinMode(12, OUTPUT);

}

void loop()

{

  digitalWrite(12, HIGH);                                   //Turn on The LED

  delay(1000);                                                   // Wait for One second

  digitalWrite(12, LOW);                                   // Turn off the LED
  delay(1000);                                                   // Wait for One second

}

 

Verify your code before uploading to the board. just by clicking on the tick button

once you receive this message, then you are good to go.

3. Upload code to Arduino Board

Once your code is ready, plug your Arduino board to your computer and click on the upload button.

DONE

your code is uploaded to your board. as you see LED start blinking with Delay of one second. you can change the delay time and play with it.

How to memorize this code? 

Connect two or more LED with different color and plug into the board. please make sure the negative and positive terminal. once you connect, then add the code. Remember the pin where you plug starting from 13 to 2. do not connect in pin 1 and pin 0.

if it is not working let me know down in the comment. 

GOOD LUCK

Do you wants learn Arduino Quick and Easy?

Introduction.

Learning Arduino never been so difficult, using Arduino a person can make an awesome project for school and universities. Arduino is an open-source platform, which means anyone can modify and rewrite, which is publicly available.

Types of Arduino

There are different types of Arduino available in the market, you can choose base on your projects.

1.     Arduino Uno

2.     Arduino Mega

3.     Arduino Nano

4.     Arduino LilyPad

5.     Arduino Leonardo

Buying Arduino Board

There are several places to buy the Arduino board, like Amazon, eBay, zero ohms, and many more. Based on your location you can check nearby Store. It is recommended to buy Starter kits with Arduino Uno R3. In the starter kits, there is various type of sensors, male-female wires, LCD display, Breadboard are available.

Getting Start with Arduino Projects

Connect your board with the computer using the USB cable provided in the kit, once you connect you will notice the LED (Light Emitting Diode) is start blinking. The bilking of the LED is the default program is set on the board. We will override this program by using Software.
