Darasi na 78: Nuna nisa daga VL53L0X akan LCD | Kwas ɗin Arduino Mataki-bi-Mataki

Ga wasu hanyoyi masu amfani da za ka iya amfani da wannan aikin:

• Ciyarwar Dabbobi ta atomatik: Auna matakin abinci a cikin kwantena don haifar da sake cikawa ko aika sanarwa.
• Kwandon Shara mai wayo: Gano yadda kwandon ya cika kuma ya faɗakar da kai lokacin da ake buƙatar zubar da shi.
• Na'urar Auna Tsayi ta DIY: Ƙirƙiri kayan aikin auna daidai don ƙananan abubuwa ko don bin diddigin girma na yaro.
• Mataimakin Yin Fakin: Gina tsarin firikwensin don taimakawa da daidaitaccen fakin a gareji ko wuri mai ƙunci.
• Robotics: Yi amfani da shi a cikin mutum-mutumi don gano abubuwan da ke hana hanya ko auna nisa zuwa bango don kewayawa.

Kayan aikin da ake buƙata

• Arduino Board (misali, Uno)
• Firikwensin Nisa na Laser VL53L0X
• Nunin LCD 1602 tare da Modul ɗin I2C
• Wayoyin Jumper

Jagorar Haɗin Waya

Haɗin waya na wannan aikin yana da sauƙi, godiya ga ka'idar I2C, wanda ke ba da damar duka LCD da firikwensin su sadarwa akan wayoyi guda biyu iri ɗaya. Firikwensin VL53L0X yana buƙatar wutar lantarki na 5V, wanda aka ɗauka kai tsaye daga fil ɗin 5V na Arduino. Don tabbatar da cewa firikwensin yana da ingantaccen tushen wutar lantarki, ana amfani da ƙarin fil a matsayin VCC na biyu. (a cikin bidiyo a 00:27)

Ga zanen haɗin:

Haɗin suna kamar haka:

• VL53L0X VCC -> Arduino 5V da Pin 13 (An saita Pin 13 azaman fitarwa na dijital don samar da ƙarin kwanciyar hankali na wutar lantarki).
• VL53L0X GND -> Arduino GND.
• VL53L0X SCL -> Arduino SCL (A5).
• VL53L0X SDA -> Arduino SDA (A4).
• LCD I2C VCC -> Arduino 5V.
• LCD I2C GND -> Arduino GND.
• LCD I2C SCL -> Arduino SCL (A5).
• LCD I2C SDA -> Arduino SDA (A4).

Idan kana amfani da wani nau'in Arduino daban, fil ɗin I2C na iya kasancewa a wani wuri dabam. Ana yawan rubuta fil ɗin SDA da SCL kai tsaye a kan allo. (a cikin bidiyo a 02:42)

Bayanin Lambar

An tsara lambar don sauƙin daidaitawa. Babban ɓangarorin da mai amfani zai iya daidaita suna a saman sketch ɗin. (a cikin bidiyo a 04:18)

Da farko, muna ayyana akai-akai don ƙarin fil ɗin wutar lantarki. Ana amfani da wannan don samar da tsaftataccen wutar 5V ga firikwensin.

const int vcc2 = 13; // Ƙarin fil ɗin VCC don firikwensin VL53L0X

Na gaba, muna ƙirƙiri misali na ɗakin karatu na LCD kuma mu ayyana adireshin I2C ɗinsa. Kana iya samun wannan adireshin ta hanyar gudanar da sketch ɗin binciken I2C, kamar yadda aka nuna a bidiyon. (a cikin bidiyo a 03:26)

LiquidCrystal_I2C lcd(0x3F, 16, 2); // Saita adireshin LCD zuwa 0x3F don nunin haruffa 16 da layi 2

A ƙarshe, akwai mai canzawa wanda ke sarrafa naúrar auna. Kana iya canza wannan ƙimar don nuna nisa a cikin millimeters ko centimeters.

const int type = 1; // Saita zuwa 1 don millimeter, 2 don centimeter

A cikin aikin setup(), an daidaita ƙarin fil ɗin VCC azaman fitarwa kuma an saita shi zuwa HIGH don samar da wutar lantarki ga firikwensin. Sannan an fara LCD ɗin.

Babban dabaru a cikin aikin loop() yana karanta nisa daga firikwensin, yana share LCD ɗin, kuma yana buga ƙimar tare da naúrar. Lokacin da type aka saita zuwa 2, ana canza nisa daga millimeters zuwa ƙimar float a centimeters don ingantaccen karatu. (a cikin bidiyo a 06:47)

Nunin Aikin Kai Tsaye

A cikin nunin, ana gwada firikwensin a kan mai auna don tabbatar da daidaitonsa. Bidiyon ya nuna cewa firikwensin yana ba da ingantattun karatu, tare da ɗan ƙaramin bambanci na millimeters kaɗan. (a cikin bidiyo a 08:32)

Yana da mahimmanci a lura cewa firikwensin yana da iyakar nisa na kusan mita 1.2 a yanayin auna ci gaba. Lokacin da abin da ake nufi ya wuce iyaka, nunin zai nuna ƙimar 8190. (a cikin bidiyo a 09:53)

Wani muhimmin abin lura shi ne cewa firikwensin na iya ba da sakamako mara inganci a saman filaye masu kyalli. Nuna shi ga abu mai sheki na iya haifar da kurakurai masu yawa, yayin da nuna shi ga saman da ba shi da sheki yana ba da sakamako daidai. (a cikin bidiyo a 10:42)

Lambar kuma tana aiki da nau'ikan VL53L0X daban-daban da manyan LCDs, kamar samfurin 2004, ba tare da canza wayoyi ba. (a cikin bidiyo a 11:30)
