Arduino va ultratovush
sensori yordamida masofani o’lchash.
Ultratovush sensori jismoniy miqdorlarni (tovushni) elektr miqdorlariga va aksincha aylantirish uchun ishlaydigan
sensordir. Ushbu sensorning ishlash usuli tovush to'lqinini aks ettirish printsipiga asoslanadi, shuning uchun u ma'lum
bir chastotali ob'ektning mavjudligini (masofasini) izohlash uchun ishlatilishi mumkin.
Arduino - bu Wiring platformasidan olingan, turli sohalarda elektronikadan foydalanishni osonlashtirish uchun
mo'ljallangan ochiq manbali bitta platali mikro kontroller. Uskuna Atmel AVR protsessoriga ega va dasturiy ta'minot
o'z dasturlash tiliga ega.
Sensor HC-SR04parallaks tomonidan ishlab chiqarilgan PING ultratovush sensorining arzon versiyasidir. Farqi
ishlatiladigan pinlarda yotadi. HC-SR04 4 ta pindan, parallaks tomonidan yaratilgan PING esa 3 ta pindan foydalanadi.
HC-SR04 sensorida tetik va chiqish pinlari alohida joylashtirilgan. Ayni paytda, agar siz Parallax-dan PING-dan
foydalansangiz, tetik va chiqish pinlari sukut bo'yicha bitta qatorga o'rnatiladi. Amalga oshirishda sezilarli farq yo'q.
Sensor belgilarining diapazoni Parallax tomonidan ishlab chiqarilgan PINGdan uzoqroqdir, bunda Parllax tomonidan
ishlab chiqarilgan PING faqat maksimal 350 sm diapazonga ega bo'lsa, HC-SR04 sensori maksimal 400-500 sm
diapazonga ega bo'lsa.
Spetsifikatsiya:
Aniqlash diapazoni: 2 sm dan 400-500 sm gacha.
Eng yaxshi aniqlash burchagi 15 daraja.
5V doimiy ish kuchlanishi.
1 sm ruxsat.
Ultratovush chastotasi 40 kHz.
To'g'ridan-to'g'ri mikrokontrollerning oyog'iga ulanishi mumkin.

Akmaljon Kuchkarov, [14.01.2022 21:24]
Radar inglizcha qisqartmasi hisoblanadi Radio Detection and Ranging, bu radio aniqlash va masofani bildiradi)
elektromagnit to'lqin tizimi bo'lib, samolyotlar, turli motorli transport vositalari va ob-havo ma'lumotlari (yomg'ir)
kabi ob'ektlarni aniqlash, masofalarni o'lchash va xaritalarini yaratish uchun foydalidir.
Radar tomonidan chiqariladigan to'lqin uzunliklari millimetrdan metrgacha o'zgaradi. Muayyan ob'ektdan chiqarilgan
va aks ettirilgan radioto'lqinlar/signallar radar tomonidan ushlanadi. Aks ettirilgan signalni tahlil qilish orqali aks
ettirilgan signalning joylashishini aniqlash va aks ettirilgan signalni keyingi tahlil qilish orqali uning turini ham aniqlash
mumkin. Qabul qilingan signal nisbatan zaif/kichik bo'lsa-da, radio signali radar qabul qiluvchisi tomonidan
aniqlanishi va kuchaytirilishi mumkin.
Ultrasonik sensorfizik miqdorlarni (tovushni) elektr kattaliklariga va aksincha aylantirish vazifasini bajaradigan sensor.
Ushbu sensorning ishlash usuli tovush to'lqinini aks ettirish printsipiga asoslanadi, shuning uchun u ma'lum bir
chastotali ob'ektning mavjudligini (masofasini) izohlash uchun ishlatilishi mumkin.

mo'ljallangan ochiq manbali bitta platali mikro kontroller. Uskuna Atm** AVR protsessoriga ega va dasturiy ta'minot
o'z dasturlash tiliga ega.
Sensor HC-SR04parallaks tomonidan ishlab chiqarilgan PING ultratovush sensorining arzon versiyasidir. Farqi
ishlatiladigan pinlarda yotadi. HC-SR04 4 ta pindan, parallaks tomonidan yaratilgan PING esa 3 ta pindan foydalanadi.
HC-SR04 sensorida tetik va chiqish pinlari alohida joylashtirilgan. Ayni paytda, agar siz Parallax-dan PING-dan
foydalansangiz, tetik va chiqish pinlari sukut bo'yicha bitta qatorga o'rnatiladi. Amalga oshirishda sezilarli farq yo'q.
Sensor belgilarining diapazoni Parallax tomonidan ishlab chiqarilgan PINGdan uzoqroqdir, bunda Parllax tomonidan
ishlab chiqarilgan PING faqat maksimal 350 sm diapazonga ega bo'lsa, HC-SR04 sensori maksimal 400-500 sm
diapazonga ega bo'lsa.

Buzzer va Arduino yordamida Jingle Bell
musiqasi.
Arduino bu elektron to'plam yoki ochiq manba elektron plata bo'lib, uning asosiy komponenti AVR tipidagi
mikrokontroller chipidir.
Mikrokontroller - bu kompyuter yordamida dasturlash mumkin bo'lgan chip yoki IC (integral sxema). Dasturni
mikrokontrollerga o'rnatishdan maqsad elektron sxema kirishni o'qishi, kirishni qayta ishlash va keyin kerakli
chiqishni ishlab chiqarishdir.
Quyida Arduino yordamida bir qator Jingle Bell musiqalari keltirilgan:
Komponentlar ro'yxati:
1 dona arduino
1 dona Buzzer
1 dona qarshilik 220 Ohm
Dastur kodi:
int buzzerPin = 8;
int tempo = 200;
char notes[] = "eeeeeeegcde fffffeeeeddedg";
int duration[] = {1, 1, 2, 1, 1, 2, 1, 1, 1, 1, 2, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 2, 2};
void playTheShit(char note, int duration) {
char notesName[] = { 'c', 'd', 'e', 'f', 'g' };
int tones[] = { 261, 293, 329, 349, 392 };
for (int i = 0; i < sizeof(tones); i++) {
// char massividan olingan eslatmani notesName massiviga bog'lash
if (note == notesName[i]) {
// Eslatmalar nomini ohanglarga bog'lang
tone(buzzerPin, tones[i], duration);
}
}
}
void setup() {
pinMode(buzzerPin, OUTPUT);
}
void loop() {
// "Eslatmalar" dan har bir belgini skanerlang
for (int i = 0; i < sizeof(notes)-1; i++) {
if (notes[i] == ' ') {
// Agar bo'sh joy topilsa, u dam oladi
delay(duration[i] * tempo);
} else {
playTheShit(notes[i], duration[i] * tempo);
}
// Eslatmalar orasidagi pauza
delay((tempo*2)*duration[i]);
}
}
Arduino yordamida raqamli Ohm o'lchagich.
Ushbu ohm-metr elektr qarshiligidan (R) o'tadigan elektr toki miqdorini o'lchash uchun galvanometrdan foydalanadi,
keyinchalik u ohmga sozlanadi. Ohm o'lchagichning asl dizayni elektr tokiga bardosh beradigan kichik batareyani
ta'minladi.
Arduino - bu Wiring platformasidan olingan, turli sohalarda elektronikadan foydalanishni osonlashtirish uchun
mo'ljallangan ochiq manbali bitta platali mikro kontroller. Uskuna Atmel AVR protsessoriga ega va dasturiy ta'minot
o'z dasturlash tiliga ega.
Arduino yordamida ohm o'lchagich sxemasi:
Komponentlar ro'yxati:
1 dona arduino
1 dona LCD belgisi
1 dona potansiyometr
1 dona qarshilik 1K
Dastur kodi:
// kutubxona kodini kiriting:
#include
const int sensorPin = A0; // Voutni sezadigan analog kirish pin
int sensorValue = 0; // sensorPin standart qiymati
float Vin = 5; // Kirish kuchlanishi
float Vout = 0; // Vout standart qiymati
float Rref = 1000; // Rezistorning ohmdagi qiymati (siz bu qiymatni kiloohm yoki megaohmda berishingiz mumkin -
sinovdan o'tgan rezistorning qarshiligi bir xil birliklarda beriladi)
float R;
// kutubxonani interfeys pinlari raqamlari bilan ishga tushiring
LiquidCrystal lcd(12, 11, 5, 4, 3, 2);
void setup() {
// LCD displeyda ustunlar va qatorlar sonini o'rnating:
lcd.begin(16, 2);
// LCD displeyga xabarni chop eting.
}
void loop() {
sensorValue = analogRead(sensorPin);
Vout = (Vin * sensorValue) / 1023; // Voutni voltga aylantiring
R = Rref * (1 / ((Vin / Vout)-1)); // qarshilikni hisoblash formulasi
lcd.print("Digital OhmMeter");
lcd.setCursor(0,1);
if(R < 15000){
lcd.print(R);
lcd.print(" Ohms");
} else lcd.print("By : Ritik");
lcd.home();
delay(1000);
lcd.clear();
