Kosakola ya VL53L0X ya mosika na Arduino

Na boyekoli oyo, tokotalela ndenge ya kosalela VL53L0X laser distance meter na Arduino. Esengeli oyo esaleli ekeseni na ndenge ya komeka bopemi na nzela ya laser, oyo esalaka ekeseni mpo na misala ndenge na ndenge lokola robotiki mpe automatisation. Na suka ya boyekoli oyo, okozala na esaleli oyo ekoki komeka bopemi mpe kolakisa yango na serial monitor.

Mpo na proje oyo, tokosalela bibliothèque ya Adafruit VL53L0X, oyo esalaka ekeseni na ndenge ya kosangisa na senseur. Bibliothèque oyo epesaka misala oyo esengeli mpo na kobanda senseur, kotanga bomekelo, mpe koyamba ba erreurs oyo ekoki kobima. Okoki kotala vidéo mpo na bokambi ya visual na mise en place (na vidéo na 02:15).

Hardware Explication

Ba composants ya liboso ya proje oyo ezali na VL53L0X laser distance meter mpe carte Arduino. VL53L0X ezali senseur ya temps de vol oyo esalelaka laser mpo na komeka bopemi kino na mètres 2 na précision ya likolo. Esalaka na nzela ya protocole I2C, oyo esalaka ekeseni na communication na Arduino.

Carte Arduino ezali lokola microcontrôleur oyo esalaka na ba données oyo ewuti na VL53L0X. Esengaka na senseur mpe ezwaka bomekelo ya bopemi, oyo ekoki kolakisa to kosalela na ba applications mosusu. Câblage ya malamu ezali moko ya makambo ya ntina mingi mpo na kozwa bomekelo ya solo.

Détails ya Datasheet

• Kokamba ete senseur ezali na courant ya malamu (2.6 V kino 3.5 V).
• Kobatela ba adresse I2C ya malamu mpo na kokima ba conflits.
• Kobatela senseur ya peto mpo na bomekelo ya bopemi ya solo.
• Kosalela ba résistances ya pull-up na ba lignes I2C soki esengeli.
• Kokima mwinda ya moi na senseur mpo na kozwa ba résultats ya malamu.

Instructions ya Câblage

Mpo na kosangisa senseur VL53L0X na Arduino, sangisa pin VCC ya senseur na pin 5V na Arduino. Pin GND esengeli kosangisa na terre (GND) ya Arduino. Mpo na communication I2C, sangisa pin SDA ya VL53L0X na pin A4 na Arduino, mpe sangisa pin SCL na pin A5. Soki ozali kosalela modèle mosusu ya Arduino, tala ba assignations ya pin SDA mpe SCL mpo na carte yango.

Na ndakisa, na Arduino Mega, okosangisa SDA na pin 20 mpe SCL na pin 21. Komeka ete ba connexions nyonso ezali ya makasi mpo na kokima ba problèmes ya communication. Soki senseur eyanoli te, tala lisusu câblage mpe komeka ete Arduino ezali na courant ya malamu.

Ba Exemples ya Code & Explication

Na nse, oyo ezali mwa ndambo ya fonction setup oyo ebandisaka senseur 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);
  }
}

Code oyo ebandisaka communication ya série mpe emekaka kobanda senseur VL53L0X. Soki senseur elongwe te, ekokoma message ya erreur mpe ekosukisa programme.

Na sima, oyo ezali mwa ndambo ya fonction loop oyo etangaka bomekelo ya bopemi:

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);
}

Bloc oyo etangaka mbala na mbala bomekelo ya bopemi na senseur mpe elakisaka yango na serial monitor. Soki bomekelo ezali na libanda ya étendue, elakisaka yango na ndenge ya malamu.

Démonstration / Nini Okomona

Ntango okosalela programme, okomona bomekelo ya bopemi elakisami na serial monitor. Ba lectures esengeli kobongwana na mbala na mbala na 100 millisecondes. Soki senseur ezali kolakisa na objet, ekolakisa bopemi na millimètres. Soki objet ezali na libanda ya étendue, ekolakisa yango mpe. Komeka senseur na kati ya étendue na yango mpo na ba résultats ya malamu (na vidéo na 10:00).
