About the 555:
The 555 timer IC was designed by Hans Camenzind in 1971. It consists of two threshold triggers, an RS flip-flop, and an output buffer. The 555 provides an easy, reliable way to create rectangular waveforms of adjustable pulse width and frequency by using different external component values. About Hans:
Hans is the plushie version of the 555 timer IC, produced by Adafruit Industries, with slightly-bendable wire-reinforced legs. He is very meticulous and precise; Hans does not like to compromise, preferring to be in a steady state until a dramatic change is called for. Hans speaks with the voice of a kindly old man with a Swiss-German accent, though his voice can become more nasally when he's upset or feels strongly about something. His catchphrase is "maybe so, but perhaps not."
