Lab 6

The document contains two Arduino programs for controlling 10 LEDs. The first program makes the LEDs blink sequentially from the 1st to the 10th and back, while the second program fades the LEDs in and out by adjusting their brightness. Both programs utilize loops and delay functions to achieve the desired LED effects.

1: Program to make 10 LEDs blink from 1st to 10th and vice


versa
#define LED_COUNT 10

int ledPins[] = {2, 3, 4, 5, 6, 7, 8, 9, 10, 11};

void setup() {

for (int i = 0; i < LED_COUNT; i++) {

pinMode(ledPins[i], OUTPUT);

void loop() {

// Blink from 1st to 10th LED

for (int i = 0; i < LED_COUNT; i++) {

digitalWrite(ledPins[i], HIGH);

delay(100);

digitalWrite(ledPins[i], LOW);

// Blink from 10th to 1st LED

for (int i = LED_COUNT - 1; i >= 0; i--) {

digitalWrite(ledPins[i], HIGH);

delay(100);

digitalWrite(ledPins[i], LOW);

4.2: Program to fade 10 LEDs:


#define LED_COUNT 10

int ledPins[] = {2, 3, 4, 5, 6, 7, 8, 9, 10, 11};

void setup() {

for (int i = 0; i < LED_COUNT; i++) {

pinMode(ledPins[i], OUTPUT);

void loop() {

// Fade in

for (int brightness = 0; brightness <= 255; brightness++) {

for (int i = 0; i < LED_COUNT; i++) {

analogWrite(ledPins[i], brightness);

delay(10);

// Fade out

for (int brightness = 255; brightness >= 0; brightness--) {

for (int i = 0; i < LED_COUNT; i++) {

analogWrite(ledPins[i], brightness);

delay(10);
