Teema 2: POTENTSIOMEETER

Katse 1.1

Ülesanne 2 Гирлянда-Valguskett

Töö kirjeldus
Valguskett töötab neljas režiimis.

Arduino UNO plaat (1tk)
Arendusplaat (1tk)
Juhtmed (11tk)
Takisti (9tk, 220 Om)
LED (9tk: 3 punane, 3 roheline, 3 kollane)
Potentsiomeetr (1tk)

Tööprotsess:

Ühendage dioodid, potentsiomeeter, takisti ja juhtmed plaadiga. Valgus töötab neljas režiimis. Punased tuled vilguvad eraldi, roheline ja kollane vilkuvad eraldi ning režiim, kus kõik kordamööda süttivad

LED-ide kasutamine

Kasutamiseks vanikutes.
