Hi I am trying to play with IOs. When connecting a small bulb directly to 3.3 and gnu it does turn on. When i am trying to do it with the tinker the light never turns on. i tried everything from D0-D7. important to say my spark is connected and when i am turning the D& to high from the tinker app the blue small led turns on.
Do I miss anything or it might be a faulty product?
