Question

Why does Arduino power supply not able to run Motor but can glow simple led?​

Answer 1

Answer:

HEY MATE HERE IS YOUR ANSWER!!

because ardunio can produce as much power if you have proper force or rotation applied .

OR

Becaues it cannot produced much energy to run motor but produced much energy to glow a led.

Explanation:

Answer 2

Add a 220 or 470 Ohm resistor between the Arduino digital output pin and the strip data input pin to reduce noise on that line. Make your wires between the arduino, power supply and the strip as short as possible to minimize voltage loss. If your strip gets damaged and doesn't work, check if the first LED is broken.
