Bayanin Kayan Aiki

Abubuwan farko na wannan aikin sune na'urar auna nisa ta laser VL53L0X da kuma modul ɗin allo na TM1637. VL53L0X na'urar auna lokacin tafiya ce wacce ke auna nisa zuwa abu ta hanyar fitar da hasken laser da kuma lissafin lokacin da yake ɗauka don hasken ya dawo. Yana aiki a ƙarfin wutar lantarki tsakanin 2.6V zuwa 3.5V amma kuma yana iya aiki da 5V saboda haɗaɗɗen mai daidaita wutar lantarki.

TM1637 mai sarrafa allo ne wanda ke sarrafa allo na 7-segment LED. Yana sadarwa ta hanyar wayoyi 2 masu sauƙi (CLK da DIO), yana sauƙaƙa haɗawa da Arduino. Allon na iya nuna lambobi kuma ya dace don nuna sakamakon nisa daga na'urar VL53L0X.

Cikakkun Bayanai na Datasheet

• Tabbatar da samar da wutar lantarki mai dacewa (5V ya isa).
• Haɗa ƙafar XSHUT don guje wa ɗigowar wutar lantarki tare da resistor na pull-up.
• Yi amfani da I2C don sadarwa; haɗa SDA da SCL yadda ya kamata.
• Kula da lokutan ƙarewa a cikin lambar don guje wa halaye marasa tsammani.
• Yi la'akari da iyakar yanayin zafin aiki don ingantaccen sakamako.

Umarnin Haɗa Wayoyi

Don haɗa VL53L0X da allo na TM1637, fara da haɗa ƙafar VCC na VL53L0X zuwa ƙafar 5V akan Arduino da ƙafar GND zuwa ƙafar ƙasa akan Arduino. Na gaba, haɗa ƙafar SDA na VL53L0X zuwa ƙafar A4 akan Arduino, wacce aka saba amfani da ita don sadarwar bayanai ta I2C. Ƙafar SCL ya kamata a haɗa zuwa ƙafar A5 akan Arduino, wacce ake amfani da ita don siginar agogo.

Don allo na TM1637, haɗa ƙafar CLK zuwa ƙafar dijital 2 akan Arduino da ƙafar DIO zuwa ƙafar dijital 3. A ƙarshe, haɗa ƙafar XSHUT na VL53L0X zuwa ƙafar dijital 12 akan Arduino. Tabbatar cewa ƙafafu marasa amfani, kamar GPIO1 akan VL53L0X, an bar su ba a haɗa su ba. Wannan tsari zai ba Arduino damar sadarwa yadda ya kamata da duka na'urar auna da allo.

Misalan Lamba da Bayani

Lambar tana fara na'urar auna da allo, tana saita sadarwar I2C, kuma tana ci gaba da karanta sakamakon nisa. A ƙasa akwai ɗan guntu da ke nuna aikin setup inda aka saita ƙafafu kuma aka fara na'urar auna:

void setup() {
  pinMode(12, INPUT_PULLUP); // saita ƙafa 12 don shigarwa
  digitalWrite(12, HIGH); // saita ƙafa 12 high (5V)
  Serial.begin(9600);
  Wire.begin(); // an fara sadarwar I2C
  sensor.init(); // an fara na'urar auna nisa
  sensor.setTimeout(500); // an saita lokacin ƙarewa
  sensor.startContinuous(); // an saita nau'in aunawa
}

A cikin wannan aikin setup, an saita ƙafar XSHUT azaman shigarwa tare da resistor na pull-up, kuma an fara na'urar auna don aunawa mai ci gaba. An kuma saita serial monitor don nuna sakamakon nisa.

Na gaba, babban loop yana karanta nisa kuma yana sabunta allo. Ga ɗan guntu mai mahimmanci daga aikin loop:

void loop() {
  int distance = sensor.readRangeContinuousMillimeters(); // karanta nisa a mm
  display.setSegments(clearLED); // cire ƙimar da ta gabata daga allo na LED
  display.showNumberDec(distance, false, 4, 0); // nuna nisa
  Serial.print("Distance: ");
  Serial.print(distance); // buga nisa akan serial monitor
}

Wannan loop yana ci gaba da karanta nisa daga na'urar auna kuma yana sabunta allo na TM1637 da sabon sakamako. Yana kuma buga nisa akan serial monitor don gyara kurakurai. Idan kuna son ganin cikakken lambar, za ta ɗora a ƙasan labarin.

Zanga-zanga / Abin da za ku Yi Tsammani

Bayan kammala saitin da ɗora lambar, ya kamata ku ga nisa da VL53L0X ya auna yana nunawa akan TM1637. Yayin da kuke matsar da abu kusa ko nesa da na'urar auna, ƙimar da aka nuna za ta canza daidai. Idan kun sami sakamako marasa tsammani, tabbatar da cewa na'urar auna ba ta da wani abu da ya rufe ta kuma saman abin ya dace don hasken laser ya dawo (a cikin bidiyo a 09:30).

Kurakurai na yau da kullun sun haɗa da haɗa wayoyi ba daidai ba ko rashin fara na'urar auna yadda ya kamata, wanda zai iya haifar da kurakuran lokacin ƙarewa. Tabbatar da cewa an haɗa ƙafafu daidai kuma na'urar auna tana da isasshen wutar lantarki don ingantaccen sakamakon nisa.
