    Reorganizing the workshop, moved a tractor tire rim to the back yard as a fire pit and lit a fire to get it started. Found an Arduion Mega board and electronic components for testing the PWM capability to drive LED for the "light dimmer" application. Tried it using the Arduino dev kit from a Mac, but it didn't see the Arduino. Tried again, but from a Linux PC and got it communicating.
