Circuite de leduri si rezistenta pentru Arduino

Recommended Posts

Salut,am cele 2 circuite din poza sunt legate intre ele ledurile sunt rosii de 3V si din cate am inteles au 20mA,sunt legate 3 in paralel si 4 in serie,exista ca de la 480mA sa fac sa iasa 20mA? ca arduino suporta doar 20mA pe pini
