Cabbidda Kaddista Laser Time-of-Flight VL53L0X Sensor-ka iyadoo la isticmaalayo Arduino

Cashiggan, waxaan ku baran doonaa sida loo cabbiro masaafada iyadoo la adeegsanayo dareemaha VL53L0X ee laser-ka ee waqtiga-duulista ee Arduino. Dareemahan wuxuu u oggolaanayaa cabbiro sax ah oo masaafo ah waxaana lagu dhex dari karaa mashaariic kala duwan, sida robotics ama nidaamyada otomaatiga. Marka aad dhammayso casharradan, waxaad awoodi doontaa inaad dejiso dareemaha, si sax ah ugu xirto, oo aad qorto koodhka lagama maarmaanka u ah si aad u hesho akhrinta masaafada.

Waxaan dabooli doonaa qaybaha qalabka ee loo baahan yahay, tilmaamaha fiilada, iyo sharaxaad faahfaahsan oo ku saabsan koodhka ka shaqeeya dareemaha VL53L0X. Si aad u hesho sawir muuqaal ah oo ku saabsan habka, hubi inaad daawato fiidiyowga la xidhiidha (fiidiyowga 00:15).

Qalabka La Sharaxay

Qaybta koowaad ee mashruucan waa dareemaha VL53L0X. Kani waa dareeme masaafo ah oo waqtiga-duulista ah kaas oo u shaqeeya isagoo sii daaya layn laser ah oo cabbiraya waqtiga ay ku qaadanayso iftiinka la celiyay inuu ku soo laabto dareemaha. Wuxuu bixiyaa cabbirada masaafada oo ku jira millimitir waxaana awood u leh inuu ku shaqeeyo masaafo kala duwan, taasoo ka dhigaysa mid ku habboon codsiyo kala duwan.

Marka laga soo tago VL53L0X, waxaad u baahan doontaa sabuurad Arduino ah si aad u habeyso xogta dareemaha. Arduino wuxuu la xidhiidhi doonaa dareemaha iyada oo loo marayo borotokoolka I2C, kaas oo u oggolaanaya isdhexgal fudud iyo xakameyn. Waxaad sidoo kale u baahan doontaa fiilooyin jumper ah si aad u xidho xiriirka ka dhexeeya dareemaha iyo Arduino.

Faahfaahinta Xaashida Xogta

• Hubi heerarka danabka ee saxda ah si aad uga hortagto dhaawaca dareemaha.
• Isticmaal resistors-ka kor u jiidaya ee khadadka I2C haddii loo baahdo.
• Ka ilaali dareemaha inuu nadiif ahaado oo aan la xannibin si aad u hesho akhrin sax ah.
• Hagaaji dareemaha deegaannada gaarka ah si aad u wanaajiso saxnaanta.
• Hubi khaladaadka waqtiga-dhamaadka ee koodhka si aad u xalliso arrimaha cabbirka.

Tilmaamaha Fiilada

Si aad ugu xidho dareemaha VL53L0X ee Arduino, bilaab adigoo ku xidhaya biinka VCC ee dareemaha biinka 5V ee Arduino. Tani waa mid badbaado leh sababtoo ah dareemuhu wuxuu leeyahay nidaamiye gudaha ah oo u oggolaanaya inuu ku shaqeeyo sahay 5V ah isagoo weli ku shaqeynaya heerarka 3.3V. Marka xigta, ku xidh biinka GND ee dareemaha biinka dhulka ee Arduino.

Hadda, ku xidh biinka SDA ee dareemaha biinka A4 ee Arduino, kaas oo ah khadka xogta ee I2C ee caadiga ah. Kadib, ku xidh biinka SCL ee dareemaha biinka A5 ee Arduino, kaas oo ah khadka saacadda ee I2C ee caadiga ah. Noocyada kale ee Arduino, biinanka SDA iyo SCL way kala duwanaan karaan; tusaale ahaan, Arduino Mega, isticmaal biinanka 20 iyo 21, siday u kala horreeyaan. Hubi in dhammaan xiriirada ay adag yihiin ka hor intaadan shidin nidaamka.

Tusaalooyinka Koodhka & Sharaxaada

Koodhka Arduino, waxaan ku bilaabaynaa inaan ku darro maktabadaha lagama maarmaanka ah oo aan bilowno dareemaha VL53L0X. Shaqada setup(), waxaan dejineynaa isgaarsiinta taxanaha ah oo aan bilowno dareemaha:

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

Qaybtani waxay bilowdaa dareemaha oo waxay bilaabataa qaabka cabbirka joogtada ah. Shaqada setTimeout(500) waxay hubinaysaa in dareemuhu uusan si aan dhammaad lahayn u laalan doonin haddii uu ku guuldareysto inuu akhriyo masaafo.

Shaqada loop(), waxaan akhrinaynaa masaafada oo aan ku daabacaynaa kormeeraha taxanaha ah:

void loop() {
  int distance = sensor.readRangeContinuousMillimeters();
  distance = distance - 55; // Ka magdhaw qaladka
  Serial.print("Masaafada: ");
  Serial.print(distance);
  Serial.print("mm");
  if (sensor.timeoutOccurred()) { Serial.print(" TIMEOUT"); }
  Serial.println();
}

Qaybtani waxay soo celisaa cabbirka masaafada oo waxay ka magdhawdaa qalad kasta oo nidaamsan adigoo ka jaraya qiime joogto ah. Waxay sidoo kale hubisaa waqtiyada-dhamaadka haddii dareemuhu ku guuldareysto inuu helo akhrin.

Muuujin / Waxa Laga Filan Karo

Markaad shubto barnaamijka, waxaad arki doontaa cusboonaysiin joogto ah oo ku saabsan masaafada uu cabbiray dareemaha VL53L0X ee kormeeraha taxanaha ah. Akhrintu waxay ku soo bixi doontaa millimitir. Haddii aad u dhaqaaqdid shay u dhow ama ka fog dareemaha, qiimaha masaafada ayaa si waafaqsan isu beddeli doona. Haddii ay jirto waqti-dhamaad, waxaad arki doontaa farriin "TIMEOUT" oo muujinaysa in dareemuhu ku guuldareystay inuu akhriyo masaafada (fiidiyowga 05:30).
