Isticmaalka Mitirka Masaafada VL53L0X Laser oo leh Arduino

Casharkan, waxaan ku baari doonnaa sida loo isticmaalo mitirka masaafada laser-ka ee VL53L0X leh Arduino. Qalabkani wuxuu kuu ogolaanayaa inaad si sax ah u cabbirto masaafada adoo adeegsanaya laser, taas oo ka dhigaysa mid ku habboon codsiyada kala duwan sida robotics iyo otomaatiga. Dhamaadka casharkan, waxaad yeelan doontaa qalab shaqeynaya oo cabbiri kara masaafada oo ku soo bandhigi kara kormeeraha taxanaha ah.

Mashruuceena, waxaan u adeegsan doonnaa maktabadda Adafruit VL53L0X, taas oo fududeyneysa habka isdhexgalka dareemaha. Maktabaddani waxay bixisaa howlaha lagama maarmaanka u ah in la bilaabo dareeraha, loo akhriyo cabbirrada, loona maareeyo wixii khaladaad ah ee soo bixi kara. Waxaad tixraaci kartaa fiidiyowga si aad u hesho hagaha muuqaalka ah ee ku saabsan dejinta (fiidiyowga 02:15).

Hardware Sharaxay

Qaybaha ugu muhiimsan ee mashruucan waxaa ka mid ah mitirka masaafada laser-ka ee VL53L0X iyo guddiga Arduino. VL53L0X waa dareeraha waqtiga-duulimaadka oo adeegsada laser-ka si loo cabbiro masaafada ilaa 2 mitir oo leh saxnaan sare. Waxay ku shaqeysaa iyada oo loo marayo borotokoolka I2C, taas oo u oggolaanaysa isgaarsiinta fudud ee Arduino.

Guddiga Arduino wuxuu u adeegaa sidii microcontroller oo ka shaqeeya xogta VL53L0X. Waxay u dirtaa amarrada dareeraha waxayna heleysaa cabbirrada masaafada, taas oo markaa la soo bandhigi karo ama loo isticmaali karo codsiyada kale. Fiilooyinka saxda ah ayaa muhiim u ah hubinta akhriska saxda ah ee dareeraha.

Faahfaahinta Datasheet

• Hubso in dareemuhu si sax ah u shaqeeyo (2.6 V ilaa 3.5 V).
• Ilaali goobaha cinwaanka saxda ah ee I2C si looga fogaado khilaafaadka.
• Ka dhig dareemaha nadiif si aad u cabbirto masaafo sax ah.
• Isticmaal iska caabin ku habboon khadadka I2C haddii loo baahdo.
• Ka fogow qorraxda tooska ah ee dareemaha si aad u akhrisato wax lagu kalsoonaan karo.

Tilmaamaha Fiilooyinka

Si aad ugu xirto dareeraha VL53L0X Arduino, ku xir biinanka VCC ee dareeraha biinanka 5V ee Arduino. Pin GND waa in lagu xiraa dhulka (GND) ee Arduino. Isgaarsiinta I2C, ku xir biinanka SDA ee VL53L0X biinanka A4 ee Arduino, oo ku xir biinanka SCL biinanka A5. Haddii aad isticmaasho nooc ka duwan Arduino, tixraac meelaynta gaarka ah ee SDA iyo SCL ee guddigaas.

Tusaale ahaan, Arduino Mega, waxaad ku xiri lahayd SDA pin 20 iyo SCL pin 21. Hubso in dhammaan xiriirada ay yihiin kuwo ammaan ah si looga fogaado dhibaatooyinka isgaarsiinta. Haddii dareemuhu uusan ka jawaabin, laba jeer hubi fiilooyinka oo hubi in Arduino si sax ah loo shaqeeyo.

Tusaalooyinka Koodhka & Socodka

Hoos waxaa ku qoran qaybo ka mid ah shaqada dejinta ee bilowga dareeraha 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);
  }
}

Koodhkani wuxuu bilaabayaa isgaarsiinta taxanaha ah wuxuuna isku dayayaa inuu bilaabo dareeraha VL53L0X. Haddii dareemuhu ku guuldareysto inuu soo kabto, wuxuu daabaci doonaa farriin qalad ah wuxuuna joojin doonaa barnaamijka.

Marka xigta, halkan waa goos goos ka mid ah shaqada loop oo akhrinaysa cabbirka masaafada:

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);
}

Balooggani wuxuu si joogto ah u akhriyaa cabbirka masaafada ee dareeraha wuxuuna ku daabacaa kormeeraha taxanaha ah. Haddii cabirku ka baxsan yahay kala duwan, waxay muujineysaa tan si waafaqsan.

Bandhig / Maxaa laga filan karaa

Markaad maamusho barnaamijka, waa inaad aragtaa cabbirrada masaafada ee lagu muujiyey kormeeraha taxanaha ah. Akhriska waa inuu cusbooneysiiyaa 100 milliseconds kasta. Haddii dareemuhu tilmaamayo shay, waxay muujin doontaa masaafada millimitir. Haddii shaygu ka baxsan yahay kala duwan, waxay sidoo kale muujin doontaa taas. Hubso inaad tijaabiso dareemaha gudahood baaxadda la cayimay si aad u hesho natiijooyinka ugu fiican (fiidiyowga 10:00).

Waqtiga Fiidiyowga

• 00:00- Hordhac
• 02:15- Dejinta fiilooyinka
• 05:30- Sharaxaadda koodhka
• 10:00- Mudaaharaad
