“Nice looking wooden analog style clock with Arduino Nano and 1mA ammeters.
I built this nice-looking wooden analog style clock with an Arduino Nano and 1mA ammeters. I got an idea from here. For displaying the seconds, a part of the code has been added. Also added is a part that, when running, passes through the entire scale from zero to max. value for calibrating purposes. Depending on what ampermeters we use, the value of the 5k resistors can be different. Because all meters are slightly different, the PWM values need to be adjusted based on your design. You will have to change some values because it is set to work specifically with my meters.”
