Koodka Arduino iyo Fiidiyowga Module-ka Fogaanta IR ee Sharp

Casharkaani waxaan ku baran doonaa sida loo isticmaalo qaybta masaafada ee Sharp IR si loo cabbiro masaafada oo loo kiciyo ficillo ku salaysan masaafada la ogaaday. Mashruucani wuxuu muujin doonaa sida loo habeeyo qalabka iyo qorista koodhka Arduino si loo akhriyo cabbirada masaafada oo loo kiciyo qalabka dhawaqa (buzzer) marka shay lagu ogaado gudaha xad gaar ah. Waxaad baran doontaa sida loo xiro qaybaha isku xirka oo aad u fahanto aqoonsiyada muhiimka ah ee koodhka ku jira.

Mashruucan, waxaan isticmaalaynaa dareeme Sharp IR oo sii daaya iftiin infir-cej ah oo cabbira masaafada shay ku salaysan iftiinka dib u soo noqda. Marka shay lagu ogaado gudaha xadka, qalabka dhawaqa ayaa la kiciyay, taasoo bixineysa hab fudud oo wax ku ool ah oo lagu muujiyo awoodaha qaybta Sharp IR. Hubi inaad fiiriso fiidiyowga si aad u hesho hagitaan muuqaal ah oo ku saabsan habaynta iyo koodhka (fiidiyowga 00:00).

Qalabka La Sharaxay

Qaybaha ugu muhiimsan ee mashruucan waxaa ka mid ah dareeme masaafada ee Sharp IR, looxa Arduino, iyo qalab dhawaq. Dareemaha Sharp IR wuxuu ka kooban yahay gudbiye iyo qaateeye oo si wada jir ah u cabbira masaafada. Marka iftiinka infir-cejka ah ee gudbiyaha uu ku dhaco shay, wuxuu dib ugu soo noqdaa qaateeyaha, taasoo u oggolaaneysa inuu xisaabiyo masaafada ku salaysan waqtiga loo qaaday iftiinka si uu u soo noqdo.

Arduino wuxuu u shaqeeyaa sidii kontoroolaha, isagoo akhriya cabbirada masaafada ee dareemaha IR oo xakameynaya qalabka dhawaqa ku salaysan akhriska. Qalabka dhawaqa wuxuu dhawaqi doonaa marka shay lagu ogaado gudaha xad go'an, taasoo ka dhigaysa habayntan mid waxtar u leh codsiyada sida ogaanshaha caqabadaha ee robotics-ka.

Faahfaahinta Xaashida Xogta

• Hubi sahayda danab ee saxda ah (4.5 – 5.5 V) si looga fogaado waxyeello.
• Isticmaal resistor si aad u xaddiddo qulqulka haddii loo baahdo.
• Nadiifi dareemaha si aad u hesho akhris sax ah.
• Ka digtoonow faragelinta iftiinka deegaanka.
• Xiridda waa inay adag tahay si looga hortago xiridda kala goysa.

Tilmaamaha Xiridda

Si aad u xirto qaybta masaafada ee Sharp IR, ku xir biinka dhulka ee qaybta biinka GND ee Arduino. Kadib, ku xir biinka VCC ee qaybta biinka 5V ee Arduino. Biinka wax soo saarka ee qaybta Sharp IR waa in lagu xiraa biinka 2 ee Arduino, kaas oo akhriyi doona xogta masaafada.

Qalabka dhawaqa, ku xir biinka dheer (togan) biinka 8 ee Arduino iyo biinka gaaban (taban) biinka GND. Hubi in dhammaan xiridda ay adag yihiin iyo in qaybaha si sax ah loo shideeyo si loo hubiyo shaqeynta saxda ah.

Tusaalooyinka Koodhka & Sharaxaadda

Hoos waxaa ku qoran qayb kooban oo ka mid ah koodhka Arduino halkaas oo aan ku qeexayno biinanka oo aan u habaynayno dareemaha. Aqoonsiga IR waxaa lagu qeexay biinka analog-ga ah ee loo isticmaalo calaamadda dareemaha.

#define IR A0 // qeex biinka calaamadda
SharpIR SharpIR(IR, model); // Bilaab SharpIR oo leh biinka la qeexay

Koodhkani wuxuu bilaabayaa dareemaha Sharp IR ee biinka analog-ga ah ee la cayimay. Aqoonsiga model wuxuu qeexayaa nooca dareemaha la isticmaalayo, kaas oo xaaladdan lagu dejiyay 1080 ee nooca GP2Y0A21YK0F.

Shaqada habaynta, waxaan ku bilaabaynaa isgaarsiinta serial si loo kormeero akhriska masaafada:

void setup() {
    Serial.begin(9600); // Bilaab isgaarsiinta serial
    Serial.println("Robojax Sharp IR  "); // Daabac farriin kormeerka serial-ka
}

Shaqada habaynta waxay bilaabaysaa isgaarsiinta serial ee 9600 baud, taasoo u oggolaaneysa Arduino inuu u diro xogta masaafada kormeerka serial-ka si loo ilaaliyo.

Gudaha shaqada loop-ka, waxaan akhriyaynaa masaafada dareemaha oo aan daabacaynaa:

void loop() {
    int dis = SharpIR.distance(); // Akhri masaafada
    Serial.print("Mean distance: "); // Daabac masaafada kormeerka serial-ka
    Serial.println(dis); // Soo saar cabbirka masaafada
}

Qaybtani waxay muujinaysaa sida si joogto ah loo akhriyo masaafada oo loo daabaco kormeerka serial-ka. Doorsoomaha dis wuxuu hayaa qiimaha masaafada ee uu cabbiray dareemaha Sharp IR.

Muuujinta / Waxa Lagu Filan Karaa

Marka habayntu dhammaato, waxaad filan kartaa in qalabka dhawaqa uu dhawaqo mar kasta oo shay lagu ogaado gudaha xadka lagu cayimay ee dareemaha Sharp IR. Kormeerka serial-ka wuxuu muujin doonaa "Mean distance" oo ay weheliso masaafada la cabbiray ee sentimitir. Haddii aysan jirin shay gudaha xadka, kormeerku wuxuu tilmaami doonaa taas sidoo kale (fiidiyowga 02:30).

Khaladaadka caadiga ah waxaa ka mid ah hubinta in dareemaha si sax ah loo toosiyay iyo in aysan jirin caqabado xannibaya calaamadda infir-cejka ah. Sidoo kale, hubi in sahayda danabku ay tahay mid deggan si looga fogaado akhriska khaldan.
