I was recently connecting an LED strand to my Arduino nano using the following wiring diagram:
I was using 10k ohm pulldown resistors in order for the LED's to be off when the Arduino is outputting a low signal but the power is plugged in. However the LED's are still on (very dim but noticeable). I was wondering if adding a bigger pull-up resistor would fix my issue?
Also if this helps I'm using the following hardware: Arduino Nano rev 3 10K ohm resistor 12V 6A 72W power supply 300 LED strand.
Thanks in advance!
