use 並聯 (1 die, other still work), 1.8V up to 3.6V different color LED use different voltage(orange , red, green, yellow are lower V)
from the standard V , + or- 1v or little different is okay! just affect the brightness, depends your LED quality, if too cheap can't stand the higher voltage, it will die |
