[ZHut] managed to bring these two worlds together by presenting how to make an Arduino blink an LED in conjunction with a 555 timer. We know, we know. It is hard to decide how to comment about this.

Indeed. Don’t worry, 555 lovers. We’ve got you covered with this Vacuum Tube 555, and and the Trollduino, a 555 on an Arduino Shield. Thanks [Matt K] for the great tip.
