Hi. I just found the topic related to this thread, at:
Flyback diodes and why you need them
as I need to drive a quartz clock motor coil with a microcontroller, and wondering how to design the snubber diode circuit.
Unfortunately I cannot see any of the pictures in the above quoted article, making the article useless. (All pictures in the article page show up as the broken picture icon.)
How do I view the article page with all of the pictures restored? FWIW, I am using Google Chrome on a Windows 10 computer.
