Building an analog clock with a microcontroller
Microcontrollers are digital devices, but in this project we will turn it around and use a PIC microcontroller to build an analog clock using a panel meter. And what's more, we will make use of the SLEEP mode of the PIC microcontroller so that this circuit can be run off of batteries and keep the time for decades when not powered on.
Thanks for watching, and let me know in the comments if you have any questions!
