In hierdie artikel maak ek 'n rotasie -aanwyser van die potensiometer met behulp van RGB Nano pixelring.

Dus, hoeveel omwentelinge op die potensiometer sal op die RGB -ring vertoon word

die komponente wat nodig is om dit te maak:

  • Arduino Nano v.3
  • RGB RING NeoPixels
  • Potensiometer
  • Jumper Wire
  • USB mini
  • Projekraad

Monteer alle komponente volgens die aftrekskema hierbo.

Arduino na Potensio en RGB -ring

+5V ==> 3. Potensio en VCC

GND ==> 1. Potensio & GND

A0 ==> 2. Potensio

D12 ==> IN

Stap 4: Resultaat

U kan die resultate in die video hierbo sien.

Elke keer as die potensiometer gedraai word, sal die nommer en kleur van die LED's op die ring dan brand volgens die aantal draaie op die potensiometer.
