Kokoma Ntalo na Laser VL53L0X Module ya Bapɛ ya 6 mpe LCD1602-I2C mpo na Arduino

Na boyekoli oyo, tokoyekola ndenge ya komeka mosika na kati ya sensor ya laser VL53L0X mpe kotalisa bapɔtɛ na LCD1602 na interface ya I2C. Projɛ oyo epesaka yo ekelá ya komeka mosika na millimètres to centimètres, mpe ezali utile mpo na misala mingi ya Arduino. Na suka ya boyekoli oyo, okozala na système ya komeka mosika oyo ezali na fonction complète mpe pete na mise en place mpe kosalela.

Mpo na kokokisa yango, tokosalela sensor ya laser VL53L0X, oyo esalaka na Arduino na nzela ya I2C. Écran LCD1602 ekolakisa polele ndenge ya mosika oyo emekami. Mpo na polele ya code, tala vidéo na (na vidéo na 00:00).

Explication ya Hardware

Biloko ya minene na construction oyo ezali sensor ya laser VL53L0X mpe écran LCD1602. VL53L0X esalelaka laser mpo na komeka mosika na précision, mpe ezali malamu mpo na misala ndenge na ndenge, lokola robotique mpe automatisation. Esalaka na communication I2C, oyo epesaka intégration pete na Arduino.

Écran LCD1602 ezali écran ya caractères na I2C oyo ekoki kolakisa bapɔtɛ 16 na nzela mibale. Esalaka ekelá ya kolakisa données ezala pete, mpo esengaka ba pins mingi te lokola ba LCD ya kala. Elongo, biloko oyo esalaka système ya komeka mosika oyo ezali na puissance mpe pete na kosalela.

Détails ya Datasheet

• Kokamba tension ya alimentation ya malamu (2.6 V kino 3.5 V).
• Kosalela ba résistances ya pull-up na ba lignes SDA mpe SCL soki esengeli.
• Kobomba sensor mosika na ba surfaces oyo ezali kongala mpo na kokima ba lectures ya mabe.
• Kokamba adresse I2C (défaut ezali 0x29 mpo na VL53L0X).
• Kokanisa na dispersion ya chaleur soki kosalelaka na environnement ya température ya likolo.

Instructions ya Câblage

Mpo na kokamba sensor VL53L0X mpe écran LCD1602, banda na kokangisa puissance mpe terre. Kokangisa pin VCC ya VL53L0X na pin 5V na Arduino mpe pin GND na terre ya Arduino. Mpo na LCD1602, kokangisa VCC na yango na 5V moko mpe GND na terre mpe.

Na sima, kokangisa ba lignes ya communication I2C. Pin SDA ya VL53L0X esengeli kokangama na pin A4 na Arduino, mpe pin SCL esengeli kokende na A5. Pin XSHUT ekoki kokangama na D12 na Arduino, kasi ekoki mpe kotikala na connexion te. Mpo na LCD1602, kokamba ete SDA mpe SCL mpe kokangama na ba pins moko na sensor VL53L0X.

Ba Exemples ya Code mpe Explication

VL53L0X sensor;

#include 
LiquidCrystal_I2C lcd(0x27, 16, 2);

void setup() {
  Serial.begin(9600);
  Wire.begin();
  sensor.init();
  sensor.setTimeout(500);
  sensor.startContinuous();
  lcd.begin();
  lcd.backlight(); 
}

Na fonction setup, tokomisaka communication série mpe bus I2C. sensor.init() ebandisaka sensor VL53L0X, mpe lcd.begin() ebandisaka écran LCD. Backlight ya écran ezali kopelama, mpo na kotala polele.

void loop() {
  int distance = sensor.readRangeContinuousMillimeters();
  Serial.print("Distance: ");
  lcd.clear();
  lcd.print("Robojax VL53L0X");
  lcd.setCursor(0,1); 
  lcd.print("Dist.: ");
  lcd.setCursor(7,1); 
  lcd.print(distance); 
  Serial.println();
  delay(100);
}

Na kati ya boucle, tozali kotanga mosika na nzela ya sensor.readRangeContinuousMillimeters() mpe kotia yango na moniteur série. LCD ezali kozwa mise à jour na mosika oyo emekami, mpe epesaka réponse na temps réel. Retard ya millisecondes 100 ekomisaka ete ba lectures ezala trop fréquent te, mpo na kotanga pete.

Démonstration / Nini Okokanisa

Ntango ezali na puissance, système ekomataka mosika na nzela ya continu mpe kolakisa bapɔtɛ na LCD. Okoki komona ba valeurs ya mosika ebongwana ntango okomema biloko pembeni to mosika na sensor. Soki ezali na mikakatano na sensor, lokola ba erreurs ya timeout, ba messages ya malamu ekomama na moniteur série (na vidéo na 03:15).
