I am using these servo driver boards with an Arduino Uno to drive many LEDs. Can I just jump and share the grounds?
I accidentally hooked up the wrong grounds and noticed the LEDs still operated as normal. Wasn't sure if this was safe or I may damage something. I am not currently using any resistors as the board max amperage is not enough to damage them. I am only using the PWM and Ground pins.
If I can, this would clean up the project immensely by reducing the volume of wiring.
