This is the actual circuit of my Arduino LED Controller - the first self-built project of mine!
The 5 switches control 1 LED each, cycling each one through 3 states - Off, On, and Flashing. The LEDs are completely independent of each other.

I like the little battery cozy it comes with. I was also impressed that there were batteries in the box for all the controllers.
This is a microcontroller-powered temperature controller for a fridge I built out of fabricated necessity and spare parts last weekend.
Backstory: We replaced our ancient 2nd fridge with a big new upright freezer, which left our little chest freezer empty. Sometimes we do need the extra fridge space though during harvest season at the farm, so I figured I could just turn the temperature up on that old chest freezer and turn it into a fridge. Nope. Highest it goes is -4C. OK. Time for some gratuitous technology. See the notes.
This is finally getting real! I hired a technician to assemble two copies of my controller board design for me. So this is officially the first prototype. Next step: set up software development environment and download some code into this puppy!

-The Fat Controller, first sketch
The controller of a railway called the Island of Sodor and only says three lines in the first sketch, but he serves as a non-speaking character in the rest of the sketches. As the narrator said at the end of the second sketch, he went on an extended holiday in South America. At the end of the fifth sketch, he had accepted a $200,5000 redundancy package before the Island of Sodor closed down.
