In my electronics course we constructed a kit for the Vellman l/O shield for arduino(pictured case). We have found a single code for a project to make the LED’s on the kit light. However we have since been unable to use the outputs of the device. Any help for resource codes or information on how to use the board would be much appreciated. The board is for Arduino Uno.
Nothing in the picture of the package that the shield came in is even remotely useful. Post a link to the device, AND the code you are trying to use, along with some PROOF, rather than saying "it don't work".
