1.Arduino kontroller to‘plamining tarkibini va imkoniyatlarini o‘rganish.
Kompyuterga Arduino IDE ni o‘rnatish.
2. Yorug‘lik diodi. Arduino yordamida yorug‘lik diodini o‘chirib yoqish.
const int LED=9; // 9 (D9) yorug’lik diodini ulash uchun oyoqcha nomeri
void setup()
{
// Yorug’lik diodi ulanadigan oyoqchani chiqish (OUTPUT) deb o’zgartiramiz
pinMode(LED,OUTPUT);
}
voidloop()
{
// oyoqchaga (HIGH) mantiqiy 1 berib yorug’lik diodini yoqamiz
digitalWrite(LED,HIGH);
//sukut1 sek (1000 ms)
delay(1000);
// oyoqchaga (LOW) mantiqiy 0 berib yorug’lik diodini o’chiramiz
digitalWrite(LED,LOW);
// sukut 1 sek (1000 ms)
delay(1000);
}
3.Tugma (Knopka). Yorug‘lik diodini yoqish misolida tugmaning bosilishiga ishlov berish. Titrashga qarshi kurashish.
#define LED_PIN 8
#define BUTTON_PIN 7
byte lastButtonState = LOW;
byte ledState = LOW;
unsigned long debounceDuration = 50; // millis
unsigned long lastTimeButtonStateChanged = 0;
void setup() {
pinMode(LED_PIN, OUTPUT);
pinMode(BUTTON_PIN, INPUT);
}
void loop() {
if (millis() - lastTimeButtonStateChanged > debounceDuration) {
byte buttonState = digitalRead(BUTTON_PIN);
if (buttonState != lastButtonState) {
lastTimeButtonStateChanged = millis();
lastButtonState = buttonState;
if (buttonState == LOW) {
ledState = (ledState == HIGH) ? LOW: HIGH;
digitalWrite(LED_PIN, ledState);
}
}
}
}
4. Potensiometr. Arduino orqali yorug‘lik diodini yorug‘lik darajasini o‘zgartirishini namoyish etish.
#include "Servo.h" // include the servo library
Servo servo; // declare a servo variable of type "servo"
void setup () {
servo. attach (10); // bind servo to port 10
pinMode (A1, INPUT ); // connect a potentiometer to input A1
}
void loop () {
int val = analogRead (A1); // read data from port A1
val = map (val, 0, 1023, 0, 180); // translate val into a new range
servo. write (val); // pass values for the servo
}
5.Potensiometrni xarakatlantirish orqali yonayotgan yorug‘lik diodining sonini o‘zgartirish(Arduinoda).
#define PIN_LED 11
#define PIN_POT A0
void setup()
{
// The pin to which the LED is connected is defined as an output
pinMode(PIN_LED, OUTPUT);
// Variable Resistor Pin Is Input
pinMode(PIN_POT, INPUT);
}
void loop(){
// Define 2 variables of type int
int rotat, brightn;
// Reading the voltage from the variable resistor into the rotat variable:
// the microcontroller will output numbers from 0 to 1023
// proportional to the rotation position of the shaft
rotat = analogRead(PIN_POT);
// Convert value to brightness. To do this, we divide rotat by 4, which, taking into account rounding, will give us a number from 0 to 255. It is this number that we will feed to the PWM output, with which you can control the brightness.
brightn=rotat/4;
// Write PWM brightness value to LED
analogWrite(PIN_LED, brightn);
}
