2 - Laboratoriya mashg’uloti nomi:
Yorug’lik diodi. Arduino yordamida yorug’lik diodini o’chirib yoqish.
Topshiriq: 20 - variant
Led pin 8; On time 300; Off time 1500:
Ulanish sxemasi

Dastur kodi:

void setup()
{
pinMode(8, OUTPUT);
}
void loop()
{
digitalWrite(8, HIGH); delay(300); digitalWrite(8, LOW); delay(1500);
}
XULOSA
Men bu laboratoriya ishini bajarib ARDUINO, led lampochka, resistor haqida bir qancha bilimlarga ega bo’ldim. Arduino yordamida yorug’lik diodini o’chirib yoqishni o’rgandim va bir qancha nazariy savollarga javob topdim.
3 - LABORATORIYA MASHG‘ULOTI NOMI:
Tugma (Knopka). Yorug‘lik diodini yoqish misolida tugmaning bosilishiga ishlov berish. Titrashga qarshi kurashish.
20 – variant
Led pin 8; button pin 5:
ULANISH SXEMASI

DASTUR KODI

}else{
digitalWrite(8, LOW);
}
}
XULOSA
Men bu laboratoriya ishini bajarib Arduino yordamida yorug’lik diodini tugma yordamida o’chirib yoqishni o’rgandim va bir qancha nazariy savollarga javob topdim.
4 - LABORATORIYA MASHG‘ULOTI NOMI:
Potensiometr. Arduino orqali yorug‘lik diodini yorug‘lik darajasini o‘zgartirishini namoyish etish.
