Luke Skywalker black and white “life sketch” alvin July 18, 2017 - 12:01pm

This is another sketch of Luke Skywalker from whatever the last Star Wars movie was called. I started with this earlier image I created, then converted it to a Gimp “life sketch” by going to Beautify > Beautify > Art > Life Sketch > 100%.

While I’m in the neighborhood, I also created this fake Luke Skywalker “hoodie” oil painting.

A simple Arduino Uno LED fade program

Shortly after writing my Arduino Uno Hello, World example, I read my documentation a little more, learned that Pin 9 on the Arduino Uno board is an analog pin, switched the LED wire to that pin, and created the following program, which slowly lights up the LED using an analog programming approach, and then fades the LED light out.

Here's the source code for my LED fade sketch:

An Arduino Uno Hello, World program

Last night I finally got some time to work with my new Arduino Uno board, and created a little "Hello, world" program. This program is just the same "LED on Pin 13" program I see repeated in every book and on every website, but it really is helpful when you're struggling to get started with the Arduino hardware, like I was.
