EX - NO.09 Led Blink and Led Pattern: Arduino Button

This document describes a circuit that uses an Arduino Uno to control 7 LEDs and display different blinking patterns when a button is pressed. The circuit connects 7 LEDs, a button, and resistors to the Arduino. When the button is pressed, the Arduino cycles through pre-programmed patterns that turn on/off each LED individually or in combinations to produce the patterns. The Arduino code uses variables to track the pattern number and control each LED pin.
