witam mam taki oto kod lecz przy wgrywaniu wyskakuje mi taki błąd jakieś pomysły?

W kodzie zdefiniowano HIGH dwa razy. W bibliotekach arduino definiowany jest HIGH 0x1 a autor programu zdefiniował 3.

https://www.youtube.com/watch?v=5WP2Tjt9o2U&t=150s mam zrobione tak jak On na filmie kod tez mam od niego, lecz zmienione w kodzie ilość ledow z 130 na 15.Czy winna może być taśma?

Może po prostu na początek weź do ręki słowniczek i sprawdź różnice między błędem, ostrzeżeniem, komunikatem. Zapoznaj się też z podstawami C++ i Arduino.
Zapewne Ci skompilowało i wgrało, przyczyn niedziałania może być dużo. Kwestia jeszcze czy skompilowało i wgrało, czy skompilowała, a nie wgrało - z tego co tu wkleiłeś nic nie wynika.

Kurcze, na jakimś filmie widziałem jak facet zna kung-fu a ja nie ? Dlaczego ?


Masz przecież czarno na białym podane kody błędów, wystarczy użyć logicznego myślenia (tym bardziej że my widzimy kawałek informacji nawet bez kodu).
