Multimeter Clock

I created this clock from three ammeters. One tells the hour, one tells minutes, and one tells seconds. There are several ways you can make the clock work: either a specifically designed PIC controller with other electrical components or a Real Time Clock chip and an Arduino Nano circuit board. I am happy to share Arduino code if you would like it to make your clock work. Or you can do what I did and have fun learning Arduino as you build the clock.
There are three holes on the back of the cl
