I am currently working me thru my box of microchips and other electronic stuff. I found some 74HC238 IC's today and gave them a try. It was no very spectacular event but it's nice to know what I have laying around when starting the next AVR project.
I used it to control 8 LED's with my Arduino using just 3 output pins. Nothing worth to show you a photo... ;)
