Ku Rakibidda Maktabadaha Loo Baahan Yahay

Sharaxaadda Koodhka

// Deji ciwaanka LCD-ga ilaa 0x27 oo loogu talagalay shaashad 16 xaraf iyo 2 saf
LiquidCrystal_I2C lcd(0x27, displayChars, displayRows);

#define TRIGGER_PIN  12  // Biinka Arduino ee ku xiran biinka trigger-ka ee dareeraha ultrasonic-ka.
#define ECHO_PIN     11  // Biinka Arduino ee ku xiran biinka echo-ga ee dareeraha ultrasonic-ka.
#define MAX_DISTANCE 190 // Masaafada ugu badan ee aan rabno inaan ping-ga u dirno (sentimitir).

• Ciwaanka LCD (0x27): Kani waa ciwaanka I2C ee module-ka LCD-gaaga. Inta badan module-yada waxay isticmaalaan 0x27, laakiin qaar ayaa laga yaabaa inay isticmaalaan 0x3F. Haddii shaashaddaadu ayan waxba muujin, waxaa laga yaabaa inaad u baahato inaad ku shubto sketch-ka iskaanka I2C si aad u hesho ciwaanka saxda ah oo aad cusboonaysiiso qiimahan. (fiidiyowga 08:11)
• TRIGGER_PIN iyo ECHO_PIN: Kuwani waxay qeexayaan biinanka dhijitaalka ah ee Arduino ee ku xiran biinanka Trig iyo Echo ee dareeraha ultrasonic-ka. Haddii aad isticmaasho biinano kala duwan, beddel qeexitaannadan.
• MAX_DISTANCE: Tani waxay dejisaa masaafada ugu badan ee sentimitir ee dareeruhu cabbiri doono. HC-SR04 wuxuu cabbiri karaa ilaa 400-500cm, laakiin dejinta qiime hoose waxay wanaajin kartaa saxnaanta iyo isku halaynta akhrinta, gaar ahaan masaafo gaaban.

1. Waxay isticmaashaa shaqada sonar.ping_cm() si ay u cabbirto masaafada oo ugu kaydiso doorsoome distance.
2. Waxay nadiifisaa LCD-ga oo daabacdaa qoraalka "Robojax.com" ee safka koowaad.
3. Kadibna waxay dhigtaa cursor-ka safka labaad oo daabacdaa "Distance: ".
4. Ugu dambeyntii, waxay u dhaqaaqdaa cursor-ka booska 10 ee safka labaad si ay u daabacdo qiimaha distance ee la cabbiray oo ay ku xigto "cm".

delay(200) ee dhamaadka loop-ka ayaa xakameeya inta jeer ee sensor-ku qaado akhrin cusub oo uu cusboonaysiiyo shaashadda.

Muuujinta Koodhka

Marka koodhka lagu shubo Arduino-gaaga, LCD-ga wuxuu iftiimin doonaa oo bilaabi doonaa inuu muujiyo masaafada. Waxaad tijaabin kartaa qaabaynta adigoo gacantaada ama shay ku dhaqaajinaya sensor-ka ultrasonic-ka ee u dhow ama ka fog. Nambarka shaashadda waa inuu ku cusboonaysiimaan waqti-qaar, isagoo muujinaya masaafada sentimitir. (fiidiyowga 38:07)
