Oldingi qo'llanmada men RGB halqa neo piksellari yordamida potentsiometr ko'rsatkichini ko'rsatdim. Buni "Potentsio indikatori RGB neopikselidan foydalanadi" maqolasida ko'rishingiz mumkin.

Va bugun men MAX7219 LED metrik displeyi yordamida potensator ko'rsatkichini ko'rsataman.

Buni amalga oshirish uchun quyidagi amallarni bajaring.

1 -qadam: kerakli komponentlar

Kerakli komponentlar:

• Arduino nano
• Potentsiometr
• Max 7219 LED matritsali displey
• Jumper simlari
• Loyiha kengashi
• USB mini
• noutbuk

Majburiy kutubxona

LedControl

2 -qadam: sxema

Komponentlarni yig'ish uchun yuqoridagi sxematik rasmga qarang, shuningdek quyidagi ma'lumotlarni ko'rishingiz mumkin:

Arduino - Led va potentsial

+5V ==> VCC va 3. Potentio

GND ==> GND & 1. Potentsial

D6 ==> DataIn

D7 ==> CLK

D8 ==> CS / Yuklash

3 -qadam: dasturlash

Aytish uchun quyidagi kodni ishlating:

#"LedControl.h" ni qo'shing

/*

Endi biz bilan ishlash uchun LedControl kerak. ***** Bu pin raqamlari sizning apparatingiz bilan ishlamasligi mumkin ***** 6 -pin DataIn -ga ulangan 7 -pin CLK -ga ulangan 8 -LOADga ulangan Bizda faqat bitta MAX72XX bor. */

LedControl lc = LedControl (6, 7, 8, 1);

imzosiz uzoq kechikish = 100;

bo'sh o'rnatish () {

lc.shutdown (0, noto'g'ri); lc.setIntensity (0, 8); lc.clearDisplay (0); } void loop () {int val = analogRead (A0); val = xarita (val, 0, 1023, 0, 8);

agar (val == 1)

{

lc.setRow (0, 0, B10000000);

}

agar (val == 2)

{lc.setRow (0, 0, B10000000); lc.setRow (0, 1, B10000000); } agar (val == 3) {

lc.setRow (0, 0, B10000000);

lc.setRow (0, 1, B10000000); lc.setRow (0, 2, B10000000); } agar (val == 4) {

lc.setRow (0, 0, B10000000);

lc.setRow (0, 1, B10000000); lc.setRow (0, 2, B10000000); lc.setRow (0, 3, B10000000); } agar (val == 5) {

lc.setRow (0, 0, B10000000);

lc.setRow (0, 1, B10000000); lc.setRow (0, 2, B10000000); lc.setRow (0, 3, B10000000); lc.setRow (0, 4, B10000000); } agar (val == 6) {lc.setRow (0, 0, B10000000); lc.setRow (0, 1, B10000000); lc.setRow (0, 2, B10000000); lc.setRow (0, 3, B10000000); lc.setRow (0, 4, B10000000); lc.setRow (0, 5, B10000000); } agar (val == 7) {lc.setRow (0, 0, B10000000); lc.setRow (0, 1, B10000000); lc.setRow (0, 2, B10000000); lc.setRow (0, 3, B10000000); lc.setRow (0, 4, B10000000); lc.setRow (0, 5, B10000000); lc.setRow (0, 6, B10000000); } agar (val == 8) {lc.setRow (0, 0, B10000000); lc.setRow (0, 1, B10000000); lc.setRow (0, 2, B10000000); lc.setRow (0, 3, B10000000); lc.setRow (0, 4, B10000000); lc.setRow (0, 5, B10000000); lc.setRow (0, 6, B10000000); lc.setRow (0, 7, B10000000); } lc.clearDisplay (0); }

4 -qadam: Natija

Dasturlashtirilgandan so'ng, natijalar shunday bo'ladi.

Agar potentio o'ngga burilsa, jonli LEDlar tobora burilishlar soniga ergashadi.

Agar qozon chapga burilgan bo'lsa, aylanish potentsialidan keyin jonli LED kamroq bo'ladi.
