Simulate this arduino uno circuit to proteus 8.

program:

// Interactive LED Flowing Lights, LEDs light up one by one in turn. Adjust the potentiometer,

// and you will find the time interval of LED lighting up changes. int ledNum = 8; //the number of the led you attach byte ledPin[] = { 2, 3, 4, 5, 6, 7, 8, 9}; // Create array for LED pins int ledDelay; // delay between changes int direction = 1; int currentLED = 0; unsigned long changeTime; int potPin = 0; // select the input pin for the potentiometer

void setup() { for (int x = 0; x

void loop()

{ ledDelay = analogRead(potPin); // read the value from the pot if ((millis() - changeTime) > ledDelay) { // if it has been ledDelay ms since last change

changeLED(); changeTime = millis(); } }

void changeLED() { for (int x=0; x Experiment 3: Interactive LED Flowing Lights In this experiment, you will learn how to change the interval of LED flashing by adjusting the potentiometer.
