Simple Clock

thingiverse

A Clock Idea I have two ideas with this clock: Make a real simple clock that requires no other hardware than the electronics. Show how it can interact and improve mechanical devices. The motor I got from Adafruit has 32 steps and a reduction ratio of 1/16.032. At first, it doesn't seem like a good choice for a clock, but technology can give the illusion of a perfect working motor. 32 steps and a ratio of 1/16.032 gives 513.034 steps per shaft revolution, divided by 60, which is 8.551 steps/second or per minute, depending on the setup. A stepper motor can only move an integer number of steps. The program will decide whether it will be 8 or 9. The human eye won't notice the difference. Here's a link to the program: https://create.arduino.cc/editor/jaconline/3bf4d5f0-314d-42f8-97cc-338978bbc35c/preview <iframe src="https://create.arduino.cc/editor/jaconline/3bf4d5f0-314d-42f8-97cc-338978bbc35c/preview?embed" style="height:510px;width:100%;margin:10px 0" frameborder=0></iframe> And for the 1/64 motor: https://create.arduino.cc/editor/jaconline/82345395-feea-4d60-89e3-76227200757a/preview <iframe src="https://create.arduino.cc/editor/jaconline/82345395-feea-4d60-89e3-76227200757a/preview?embed" style="height:510px;width:100%;margin:10px 0" frameborder=0></iframe> I've also included a program for the same motor with a 1/64 ratio that's easily found on Ebay and other places. The Arduino timekeeping is not very accurate, depending on the board. I got a few minutes to up to 20 minutes variation per week. I see it more as a learning experience. Please comment if you'd like or want to add to it.
