Amfani da LCD tare da Digispark USB don nuna rubutu | Robojax

Ra'ayoyin Aiki:

• Ƙirƙirar agogon dijital mai sauƙi.
• Nuna karatun na'urori (zazzabi, ɗanshi, da sauransu).
• Gina alamar matsayi na al'ada don babban aiki.
• Haɓaka wasa mai sauƙi tare da amsa a kan allo.

Kayan aiki / Abubuwan Haɗi

Aikin yana amfani da allo na LCD 1602 (haruffa 16 x layi 2) (a cikin bidiyo a 00:21), microcontroller na Digispark (ko USB ko micro USB version – haɗin yana kama da yawa, amma haɗin zuwa kwamfuta ya bambanta (a cikin bidiyo a 00:34)), da wayoyi masu haɗawa. Allon LCD ya haɗa da na'urar sadarwa ta I2C (a cikin bidiyo a 00:56), hasken baya, da potentiometer don daidaita hasken allo (a cikin bidiyo a 01:31).

Jagorar Haɗin Waya

Haɗin waya kamar haka ne (a cikin bidiyo a 02:09):

• LCD Ground zuwa Digispark Ground
• LCD VCC zuwa Digispark 5V
• LCD SDA zuwa Digispark Pin 0
• LCD SCL zuwa Digispark Pin 1

Bayanin Lambar

Lambar Arduino tana amfani da ɗakin karatu na LiquidCrystal. Muhimmanci, kana buƙatar sanin adireshin I2C na LCD ɗinka ta amfani da na'urar binciken I2C (a cikin bidiyo a 03:36). Wannan adireshin (yawanci ƙimar hexadecimal kamar 0x3F, 0x27, ko 0x38) dole ne a shigar da shi a cikin lambar (a cikin bidiyo a 03:29). Lambar kuma tana bayyana adadin ginshiƙai (16) da layuka (2) na LCD (a cikin bidiyo a 05:57). Aikin setup() yana fara LCD kuma yana buga saƙon farko. Aikin loop() yana ci gaba da share LCD, buga "RoboJax" a layi na farko, da "Hello World!" a layi na biyu (a cikin bidiyo a 06:54), tare da jinkirin rabin daƙiƙa tsakanin sabuntawa (a cikin bidiyo a 07:46).

// ... (sauran lambar da aka tsallake) ...
const int rs = 12, en = 11, d4 = 5, d5 = 4, d6 = 3, d7 = 2;
LiquidCrystal lcd(rs, en, d4, d5, d6, d7);
// ... (sauran lambar da aka tsallake) ...
//Wannan layin yana saita adireshin I2C na LCD
lcd.begin(16, 2); //Wannan layin yana saita girman LCD
// ... (sauran lambar da aka tsallake) ...

Aiki / Nunin Kai Tsaye

Bidiyon yana nuna nasarar haɗa da loda lambar zuwa Digispark (a cikin bidiyo a 08:20). LCD yana nuna rubutun da aka tsara, yana tabbatar da aikin da'irar (a cikin bidiyo a 08:48).
