Stripled to VMA01

Hi all,

i’ve arduino uno, and i bough vma01 shield. i’ve done the sketch and everything seems worked, because i want to connect first of 1 strip led rgb, and was working when:

  • The AC Adapter that output 12V, and 5 A was connected to the Arduino directly.

Afte rthat on arduino community they suggest to attach the adaptor directly to the shield, using the PWR, result? nothing is working. when i attach also the usb, to my pc, only the central led are working but stripled is off. Any idea? should i take back to Power on Arduino?
