User-Control LED

My first Adruino Project- (Complete Beginner).

In this the user can control the following through the serial monitor :

• the number of cycles the LED blinks.
• the number of times the LED blinks in each cycle.
• each "blinking" time as well as each "not-blinking" time in each cycle.

Requirements

• an arduino.
• an adruino IDE installed on the computer.
• an USB to connect the arduino to the computer.

Description

The code is made to work on the LED connected to pin 13 (Digital I/O pin) of the arduino.

If anybody desires to use an external LED then follow the following:

• connect the LED in series with a suitable resistor(usually 330ohms) on a bread-board.
• the power to the LED can be supplied from the arduino - connect the positive terminal of the LED to any Digital I/O pin on the arduino (except pin 0 and 1 which are TX and RX pins) and the negative terminal to any one of GND(ground) pin on the arduino.
• Changes to be made in the code - change the value of x from 13 to whichever pin you have chosen.

Additional feature that can be added

the brightness of the LED in each blink can also be made user-dependent

• add an additional array variable in the code.
• ask the user to enter the brightness of each blink from the serial monitor and store it in the array added.
• use analogWrite instead of digitalWrite
• connect the positive terminal of the LED to an analog pin (~PWM) and change the value of x respectively.
