LED BLINKING using arduino

LED BLINKING USING ARDUINO MEGA

This is a series of simple projects aimed at getting started with Arduino. This will cover most of the important peripherals of the Arduino starting from simple Digital I/Os to ADC and communication interfaces etc.

In the first set of projects the following are included. They are basically about the Digital I/Os and ADC on the arduino.

1.LED BLINKING
2.LED ON using push button
3.AC BULB ON using push button
4.Running LED'S
5.Running LED'S when button pressed
6.LED ON/OFF using two buttons
7.LED BLINK with adjustable delays
8.POTENTIOMETER as ADC input display serial monitor
9.LDR light controller
10.LED ON/OFF USING PIR SENSOR
11.Temperature controller

In this experiment we are going to see

LED BLINKING:

Turns on an LED on for one second, then off for one second, repeatedly.

Most Arduinos have an on-board LED you can control. On the Uno and
Leonardo, it is attached to digital pin 13. If you're unsure what
pin the on-board LED is connected to on your Arduino model,
