Amfani da VL53L0X Laser Distance Meter tare da Arduino

A cikin wannan darasa, za mu bincika yadda za a yi amfani da ma'aunin laser na VL53L0X tare da Arduino. Wannan na'urar tana ba ku damar auna nesa daidai ta amfani da laser, yana mai da shi manufa ga aikace-aikace daban-daban kamar mutum-mutumi da sarrafa kansa. A ƙarshen wannan koyarwar, za ku sami saitin aiki wanda zai iya auna nesa kuma ya nuna su a cikin mai saka idanu.

Don aikinmu, za mu yi amfani da ɗakin karatu na Adafruit VL53L0X, wanda ke sauƙaƙa tsarin hulɗa tare da firikwensin. Wannan ɗakin karatu yana ba da ayyukan da ake buƙata don fara firikwensin, karanta ma'auni, da kuma kula da duk wani kuskuren da zai iya tasowa. Kuna iya komawa zuwa bidiyon don jagorar gani akan saiti (a cikin bidiyo a 02:15).

Hardware ya bayyana

Manyan abubuwan da ke cikin wannan aikin sun haɗa da mita mai nisa na laser VL53L0X da allon Arduino. VL53L0X firikwensin lokaci ne wanda ke amfani da laser don auna nesa har zuwa mita 2 tare da babban daidaito. Yana aiki ta hanyar yarjejeniyar I2C, yana ba da damar sadarwa mai sauƙi tare da Arduino.

Kwamitin Arduino yana aiki a matsayin microcontroller wanda ke sarrafa bayanai daga VL53L0X. Yana aika umarni zuwa firikwensin kuma yana karɓar ma'aunin nesa, wanda za'a iya nunawa ko amfani dashi a wasu aikace-aikace. Ingantaccen wiring yana da mahimmanci don tabbatar da ingantaccen karatu daga firikwensin.

Bayanan Bayanai

• Tabbatar cewa firikwensin yana da ƙarfi daidai (2.6 V zuwa 3.5 V).
• Kula da saitunan adireshin I2C daidai don kauce wa rikice-rikice.
• Ajiye firikwensin a tsabta don ma'aunin nesa daidai.
• Yi amfani da masu tsattsauran ra'ayi a kan layi na I2C idan ya cancanta.
• Guji hasken rana kai tsaye a kan firikwensin don karatu mai aminci.

Umarnin Wiring

Don haɗa firikwensin VL53L0X zuwa Arduino, haɗa fil ɗin VCC na firikwensin zuwa fil 5V akan Arduino. Dole ne a haɗa fil ɗin GND zuwa ƙasa (GND) na Arduino. Don sadarwa ta I2C, haɗa fil SDA na VL53L0X zuwa fil ɗin A4 akan Arduino, kuma haɗa fil ɗin SCL zuwa fil ɗin A5. Idan kuna amfani da samfurin Arduino daban-daban, koma zuwa takamaiman SDA da SCL pin assignments don wannan hukumar.

Alal misali, a kan Arduino Mega, zaku haɗa SDA zuwa fil 20 da SCL zuwa fil 21. Tabbatar cewa duk hanyoyin sadarwa suna da aminci don kauce wa matsalolin sadarwa. Idan firikwensin bai amsa ba, duba wiring sau biyu kuma tabbatar da cewa Arduino yana da ƙarfi yadda ya kamata.

Misalai na Code & Walkthrough

Da ke ƙasa akwai snippet daga aikin saitin wanda ke ƙaddamar da firikwensin VL53L0X:

void setup() {
  Serial.begin(9600);
  while (! Serial) {
    delay(1);
  }
  Serial.println("Robojax Test");
  if (!lox.begin()) {
    Serial.println(F("Failed to boot VL53L0X"));
    while(1);
  }
}

Wannan lambar tana farawa da sadarwa ta serial kuma tana ƙoƙari don fara firikwensin VL53L0X. Idan firikwensin ya kasa kunnawa, zai buga saƙon kuskure kuma ya dakatar da shirin.

Na gaba, a nan ne snippet daga aikin madauki wanda ke karanta ma'aunin nesa:

void loop() {
  VL53L0X_RangingMeasurementData_t measure;
  lox.rangingTest(&measure, false);
  if (measure.RangeStatus != 4) {
    Serial.print("Distance (mm): "); Serial.println(measure.RangeMilliMeter);
  } else {
    Serial.println(" out of range ");
  }
  delay(100);
}

Wannan toshe yana ci gaba da karanta ma'aunin nesa daga firikwensin kuma ya buga shi zuwa mai saka idanu. Idan ma'aunin ya fita daga kewayon, yana nuna wannan daidai gwargwado.

Zanga-zangar / Abin da za a yi tsammani

Lokacin da kake gudanar da shirin, ya kamata ka ga ma'aunin nesa da aka nuna a cikin serial monitor. Ya kamata a sabunta karatun kowane milliseconds 100. Idan firikwensin yana nuna wani abu, zai nuna nesa a milimita. Idan abu ya fita daga kewayon, zai nuna hakan ma. Tabbatar gwada firikwensin a cikin kewayon da aka ƙayyade don sakamako mafi kyau (a cikin bidiyo a 10:00).
