Hi, so i've been dreaminf of this project for a while. The idea is, 24 1m, 30led/m strips, cut in half, to make a display 15 led high and 48 led long, all handled by a teensy board to interpret an audio signal and send the correct signal to the leds. Thing is, i only know which strips to choose, and the power supply, but idk what else do i need for it.

Just for reference, i am basing my design on this one:

But since its just a showcase, not a tutorial, there arent many details. I was gonna copy his method of powering it up too, power in parallel, signal in series.

Could you guys point me in the correct direction a bit, at least in terms of hardware/materials required?

Thank you all so much in advance!!!
