I actually have around 130 LEDS, the strips will just show how many LED sections (idk if thats the right word?) are there. also the strips i have do require a direct connection to the power supply, but i wasnt able to figure out how to simulate that on Tinkercad. i am going to connect the strips directy to the power supply tho
On a similar note, do i have to connect each strip's 5V and GND connection to the arduino? or is it better to connect that to the power supply? heres a pic of the strip, if it helps
the red wires are 5V, the middle (turquoise?) wire is the input/output, and the white and light-greenish wires are GND
