I'm new to the forum and arduino projects and I have searched for answer to my query. Can someone please tell me if I'm on the right track here...
Goal: connect 3x 5m ws2812b (150 led version) in series = 450 leds = 22.5 amp potential max current
Controller: arduino uno (7-12V input, 5V output)
Power supply: 5V DC, 30 amp.
Newbie question: should I attempt to power the 5V LEDs through the arduino board (7-12V input, 5V output) or power the board separately using a low current 9-12V adapter and connect the 5V, 30 amp power supply directly to 3x ws2812 strips?
My rookie intuition tells me passing a high current draw through the board to power all those LEDs is not the best solution. Secondly, I cannot find a 7-12V power supply with high current (> approx 8 amps), which would also seem to indicate it's not a good idea.
