LED Pattern 3 with ATmega16

3314

In this project, we will learn How to generate different patterns in a 1×8 LED array with AVR ATmega16 microcontroller. First, we will connect the 8 LEDs with 8 pins of any port of the ATmega16 microcontroller. Then, we will generate the below pattern in the 1×8 LED array. The pattern is shown in below diagram:

0	1	2	3	4	5	6	7	LED Position
x	x	x	x	x	x	x	x	Initial State of LEDs
*	x	x	x	x	x	x	x	2nd State of LEDs
*	*	x	x	x	x	x	x	3rd State of LEDs
*	*	*	x	x	x	x	x	4th State of LEDs
*	*	*	*	x	x	x	x	5th State of LEDs
*	*	*	*	*	x	x	x	6th State of LEDs
*	*	*	*	*	*	x	x	7th State of LEDs
*	*	*	*	*	*	*	x	8th State of LEDs
*	*	*	*	*	*	*	*	Final State of LEDs

In the above diagram, * means LED is on and x means LED is off. The time interval between each state is 500ms and the above pattern continues forever.
