2025 Avtor: John Day | [email protected]. Nazadnje spremenjeno: 2025-01-23 15:08

V tem članku bom naredil indikator vrtenja potenciometra z uporabo obroča RGB Nano Pixel.

Torej, koliko vrtljajev na potenciometru bo prikazanih na obroču RGB

Korak: Potrebne komponente

komponente, potrebne za njegovo izdelavo:

• Arduino Nano v.3
• RGB RIng NeoPixels
• Potenciometer
• Mostična žica
• Mini mini USB
• Projektni odbor

2. korak: Shema vezja

Vse komponente sestavite v skladu z zgornjo shemo črpanja.

Arduino na Potensio in RGB Ring

+5V ==> 3. Potensio in VCC

GND ==> 1. Potensio & GND

A0 ==> 2. Potenzio

D12 ==> IN

3. korak: Programiranje

Kopirajte spodnjo kodo in jo prilepite v skico

#include #ifdef _AVR_ #include // Potrebno za 16 MHz Adafruit Trinket #endif

#define PIN 12

#define NUMPIXELS 16

Slikovne pike Adafruit_NeoPixel (NUMPIXELS, PIN, NEO_GRB + NEO_KHZ800);

#define DELAYVAL 10

void setup () {

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

4. korak: Rezultat

Rezultate si lahko ogledate v zgornjem videu.

Tako se vsakič, ko potenciometer zavrtite, zasveti število in barva LED na obroču glede na število obratov na potenciometru.
