Darasi na 29/31: Mota-7 Sarrafa Motar SunFounder Smart ta amfani da Remote Controller | Robojax

A wannan darasin, za mu canza motar SunFounder mai wayo zuwa motar da ake sarrafa ta daga nesa ta amfani da infrared (IR) remote. Maimakon dogaro da haɗin waya ko manhajar wayar hannu, za ku koyi yadda ake tsara maɓallan kan daidaitaccen IR remote don sarrafa motsin motar—gaba, baya, juyawa, har ma da motsin diagonal—da kuma daidaita saurinta a kan tafiya. Wannan aikin shine mataki na gaba mai kyau bayan koyon tushen sarrafa motar da sadarwar IR, domin yana haɗa duka biyun cikin tsari guda mai mu'amala.

Ƙimar gaske a nan tana cikin fahimtar yadda ake ƙirƙirar ingantaccen tsarin sarrafawa mai sauƙin amfani ga dandalin robotics. Ƙa'idodin da za ku koya suna aiki kai tsaye ga fannoni da yawa na ayyuka, kamar:

• Gina robot mai sarrafa nesa don ayyukan sarrafa gida, kamar ƙaramin motar isar da kaya.
• Ƙirƙirar motar da za a iya tsarawa don gasar robotics ta ilimi.
• Haɓaka remote na musamman don faifan kyamara ko na'urar juyawa.
• Ƙirƙirar samfurin mu'amalar mai amfani don babban tsarin sarrafawa mai rikitarwa.

Kayan aiki da Abubuwan Haɗi

Wannan aikin ya ginu a kan SunFounder 3-in-1 Arduino kit. Don ci gaba, za ku buƙaci abubuwan da aka jera a ƙasa. Haɗin waya yana da sauƙi, yana ƙara daga darussan da suka gabata a cikin kwas ɗin.

• SunFounder 3-in-1 Arduino Kit: Wannan ya haɗa da chassis na motar wayo, allon sarrafa motar, da allon Arduino.
• Infrared Remote Control: Remote ɗin daidaitaccen da ke zuwa tare da kit ɗin.
• IR Receiver Module: Na'urar da za ta fassara siginonin daga remote.
• LED da 330-ohm Resistor: Ana amfani da su azaman alamar gani don tabbatar da an danna maɓalli. (a cikin bidiyo a 04:08)
• Jumper Wires: Don yin haɗin da ake buƙata a kan breadboard.

Jagorar Haɗin Waya

Kafin mu shiga cikin lambar, bari mu tabbatar da cewa kayan aiki an haɗa su daidai. Haɗin waya na IR receiver da na sarrafa motar ya yi daidai da darussan da suka gabata a cikin wannan jerin. Don ƙara mu'amala ga aikin, za mu kuma haɗa LED na waje zuwa pin 13 azaman alamar amsawa ta gani.

Ga jagora mataki-mataki na haɗin:

1. IR Receiver: IR receiver yana da pins uku. Pin mai kyau yana haɗawa zuwa layin 5V akan breadboard. Pin na ƙasa yana haɗawa zuwa layin GND. Pin na sigina, wanda shine pin na ƙarshe, yana haɗawa zuwa dijital pin 11 akan allon Arduino ɗin ku. (a cikin bidiyo a 05:29)
2. LED na Waje: Haɗa ƙafa ɗaya na 330-ohm resistor zuwa dijital pin 13 akan Arduino. Haɗa ɗayan ƙafar resistor zuwa ƙafar (anode) mai tsawo na LED. Ƙafar (cathode) gajeriyar LED ɗin ya kamata a haɗa zuwa layin GND akan breadboard. (a cikin bidiyo a 04:08)
3. Sarrafa Motar: Pins huɗu na sarrafa motar (A_1B, A_1A, B_1B, B_1A) an haɗa su zuwa pins 5, 6, 9, da 10 akan Arduino, bi da bi. Wannan saitin an riga an yi bayaninsa a darussan da suka gabata. (a cikin bidiyo a 06:44)

Don samun misalin gani na waɗannan haɗin, da fatan za ku koma ga zanen haɗin waya a ƙasa.

Bayanin Lambar

Lambar wannan aikin an tsara ta don zama mai sauƙin fahimta. Tana amfani da ɗakin karatu na IRremote don sarrafa aikin rikitarwa na fassara siginonin IR. Bari mu raba sassan da mai amfani zai iya daidaitawa waɗanda kuke iya son canzawa don ayyukanku.

A saman sketch ɗin, za ku sami ma'anar pins. Waɗannan su ne abubuwan farko da ya kamata ku duba idan kun haɗa abubuwan ku zuwa pins daban-daban fiye da waɗanda aka yi amfani da su a wannan misalin.

const int IR_RECEIVE_PIN = 12;  // Ayyana lambar pin don IR Sensor
const int A_1B = 5;
const int A_1A = 6;
const int B_1B = 9;
const int B_1A = 10;

• IR_RECEIVE_PIN: Wannan ma'anar tana ayyana dijital pin da aka haɗa zuwa pin na sigina na IR receiver ɗin ku. Idan kun haɗa shi zuwa wani pin daban, za ku canza lambar a nan.
• A_1B, A_1A, B_1B, B_1A: Waɗannan ma'anoni suna nuna pins huɗu na sarrafawa akan sarrafa motar ku. Suna sarrafa saurin da alkiblar motocin hagu da dama.

Na gaba, za ku sami muhimmin ma'auni wanda ke sarrafa halayen motar.

int speed = 150;

• speed: Wannan ma'auni yana saita saurin farko na motar. Ƙimar na iya kasancewa daga 0 zuwa 255. A cikin wannan aikin, za ku iya canza shi ta amfani da maɓallan "+" da "-" akan remote. Lambar kuma ta haɗa da dabaru don hana saurin wuce 255 ko faɗuwa ƙasa da 0. (a cikin bidiyo a 09:22)

Muhimmin dabaru na sarrafa nesa ana sarrafa shi a cikin aikin loop(). Lokacin da aka danna maɓalli, aikin decodeKeyValue() yana fassara lambar IR ɗin zuwa saƙo mai sauƙi kamar "2" don gaba ko "+" don ƙara sauri. Wannan yana sa bayanan if da ke biye su zama masu sauƙin karantawa da canzawa. (a cikin bidiyo a 07:58)

Nunin Aikin Kai Tsaye

Tare da ɗora code ɗin kuma motar tana kunne, remote control ɗin ya zama babbar hanyar sadarwarka. Nunin a cikin bidiyon yana nuna wasu muhimman halaye:

• Sarrafa Saurin: Danna maɓallin "+" yana ƙara saurin da 50, yayin da maɓallin "-" ke rage shi. Saurin yana da iyaka a 255 kuma yana ƙasa a 0 don kare motocin. (a bidiyo a 11:56)
• Motsi na ɗan lokaci: Lokacin da ka danna maɓallin jagora kamar "2" (gaba) ko "8" (baya), motar za ta motsa na daƙiƙa ɗaya sannan ta tsaya kai tsaye. Wannan fasalin tsaro ne da aka gina a cikin code ɗin. (a bidiyo a 13:09)
• Juyawa da Gudanarwa: Maɓallan da aka tsara a tsarin giciye akan remote ɗin suna aiki kamar joystick. Danna "4" ko "6" zai juya motar hagu ko dama a wuri. Danna maɓallan diagonal, kamar "1" ko "3", zai yi "motsi hagu" ko "motsi dama," wanda shine juyi mai kaifi inda ƙafa ɗaya ke tsaye. (a bidiyo a 16:42)

Abu ɗaya da za ka iya lura shine motar ba koyaushe take tafiya a layi madaidaici ba. Wannan sau da yawa saboda ƙananan bambance-bambance a cikin motocin ko ƙarfin haɗin motar, wanda al'ada ce ta gama gari kuma ta al'ada na waɗannan kayan. (a bidiyo a 15:14)
