Months ago I bought 3 RGB led strip (1 meter, 60 leds) and now I want to use it on a project.
The specification said
I struggle with the power supply and the type of circuit I need for this, series vs parallel. If I choose series circuit :
3 * 5V = 15V
3*18W = 54W and then 54/15 = 3.6A
I found a laptop power supply with 15V and 4A, how can use it with my circuit ?
With parallel circuit :
3.6A * 3 = 10.8A
What is the best solution to connect the 3 strips together ?
