About Power Supply? Answered
Supposed my LED Strip 5 meter.
60 LEDs (pixel) per 1 meter and 60mA per pixel then I will need:
60mA * 60 Pixel = 3600 mA = 3.6 A max
Arduino need about 50mA.
Total I will need: 60mA * 300 (pixel) + 50mA = 18050mA (about 18.05A).
It is possible to use external power supply 5V with 30A or 60A for this 5m LED Strip?
