You Can Simulate a 555 Timer in 123D Circuits

It is an absolute joy to make this announcement about a tiny, unassuming chip that has changed the world:  You read it first here.  You can simulate a 555 in 123D Circuits!

Whether you knew it or not, we've all touched a 555.  They're inside appliances like toaster ovens, microwaves, alarm clocks, little robots, zillions of toys, early computers and even a few spacecraft.  They're everywhere!

Don't believe us?  According to their original 1971 inventor, Hans Camenzind, production has steadily ramped up to an astonishing 1 BILLION 555s being made per year, and they crossed that threshold in 2003!


For the announcement we put together an example circuit that when connected to a servo lets you control the angle (or position) by turning a potentiometer.  Click the Read More button to load it.   Read more »
