Different Task Using Arduino UNO

Objective:

To learn Arduino board and programming for LED blinking using Arduino.

Introduction:

1. Arduino UNO

The Arduino Uno is an open source microcontroller board based on the Microchip ATmega328P and developed by Arduino.cc. It has 14 digital input/output pins ,6 analog input/output pins, and is programmable with the Arduino IDE (Integrated Development Environment). It contains everything needed to support the microcontroller ; simply connect it to a computer with a USB cable or power it with a AC-to-DC adapter or battery to get started..

2.LED( Light-Emitting-Diode):

A Light Emitting Diode (LED) is a semiconductor light source that emits light when current flow through it.

Task 01 : LED Blink Using Arduino Uno

Task to blink a LED for time interval of 1 second.

Equipment’s :

• LED(1)

• Arduino Uno(1)

• Resistor 220 ohm(1)

• Jumper Wires

• Bread Board(1)

Software Used :

• Arduino IDE
• Tinker CAD

connection For Arduino:

Connect the long leg of the LED (the positive leg, called Anode) to the resistor and other end of the resister to the digital pin of Arduino . Connect the short leg of the LED (the negative leg ,called Cathode) to the GND.

Sketch For Arduino:

int led =7;
void setup() {
pinMode(7, OUTPUT);
}

void loop()

{
digitalWrite(7, HIGH);
delay(1000);
digitalWrite(7, LOW);
delay(1000);
}

Algorithm:

1. Set the pin to HIGH(5v),this will turn the LED on.
2. wait for 1000 millisecond .
3. Set the pin to LOW (0v),cutting the power of LED and turning it off.
4. Wait for 1000 millisecond and then repeat again.

Application:

Blinking LED light can be used in,

• Traffic Signal Lights
• Home Decoration
• vehicles Indicators
