Hello everyone,
I'm new in this forum
I built a ceiling led to my aquarium and I want to deal with Arduino.
in total I have 37 LEDs including 30 to be used to simulate daylight and the remaining seven to the moon.
I would like advice on which dimmer used to simulate the effect dawn sunset.
especially if you connect it directly to the board Arduino UNO (so no external power supply).
if you buy a dimmer with more wattage than what I need risk of burning LEDs?
the same thing is true for the amperage? (LEDs work 350 mah)
I was advised to buy one with a rating slightly higher to ensure that not too much effort while working.
sorry for these questions that seem silly to you, but I'm just ushering the world circuit.
