Back and forth thing of wonder. Day 4. Eh…
embedded by Embedded Video
So, the thing I kept trying to make kept breaking every chance it got. Finally, it somehow turned into this. Basically, I whipped something together using the slide mechanism from inside a printer, an Arduino, a junky photocell controlled H-bridge left behind by one of my least promising students this summer and the relay controlled extension cord I used in the penguin.
In short, as the thing moves back forth, it hits a switch which turns a lamp on or off which in turn changes the direction its moving in. There’s two seperate circuits at work. Yup… that’s pretty much it.
