I am using a TFT LCD shield that connects directly to my board. It draws 5 volts, and since I am using a 5v power supply to power the board, I can't connect 2 components that both use 5v. Therefore I use two power supplies.
How do I prevent this? This is exactly what I am wanting to prevent. LED strips from big brands like Phillips have it so when you turn the strip off and on via Bluetooth or using a remote, it goes back to what you last had it set to. This is exactly what I want to achieve.
My bad. I have a 300 LED strip. Though I will be extending it with 2 more strips with 300 LEDs on each strip.
Which is why I don't mind if I had to turn the strip black programmatically rather than completely drawing the power from the strip (I don't know if turning the strip black programmatically is the same thing as drawing the power)
So how can I prevent the LED strip from losing its memory when I turn it off? Allowing the LED strip to remember its last state? I am unaware of any sort of products in which could be added to my project to do this exact thing..
