Ushbu maqolada men RGB Nano pikselli uzuk yordamida potansiyometrning aylanish ko'rsatkichini tuzaman.

Shunday qilib, potentsiometrda qilingan qancha inqilob RGB halqasida aks etadi

1 -qadam: kerakli komponentlar

ishlab chiqarish uchun zarur bo'lgan komponentlar:

• Arduino Nano v.3
• RGB Ring NeoPixels
• Potentsiometr
• Jumper simlari
• USB mini
• Loyiha kengashi

2 -qadam: O'chirish sxemasi

Yuqoridagi sxemaga muvofiq barcha komponentlarni yig'ing.

Arduino - Potensio va RGB halqalariga

+5V ==> 3. Potensio va VCC

GND ==> 1. Potensio va GND

A0 ==> 2. Potensio

D12 ==> IN

3 -qadam: dasturlash

Quyidagi kodni nusxa ko'chiring va eskizga joylashtiring

#include #ifdef _AVR_ #include // 16 MGtsli Adafruit Trinket uchun zarur #endif

#PIN 12ni aniqlang

#NUMPIXELS 16 ni aniqlang

Adafruit_NeoPixel piksellari (NUMPIXELS, PIN, NEO_GRB + NEO_KHZ800);

#kechiktirishni belgilang 10

bo'sh o'rnatish () {

#if aniqlangan (_ AVR_ATtiny85_) && (F_CPU == 16000000)

clock_prescale_set (clock_div_1); #endif

piksel.begin ();

piksel.setBrightness (10);

Serial.begin (9600); }

bo'sh halqa ()

{piksel.clear (); int val = analogRead (A0); val = xarita (val, 0, 1023, 0, 18);

4 -qadam: Natija

Natijalarni yuqoridagi videoda ko'rish mumkin.

Potentsiometr har gal aylantirilganda, halqadagi LEDlarning soni va rangi potansiyometrda qilingan burilishlar soniga qarab yonadi.
