Three voltmeters combined into one clock any engineer would love

Three voltmeters combined into one clock any engineer would love

Arduino TeamJanuary 30th, 2019

Apparently not satisfied with available timekeeping devices, ElegantAlchemist crafted a unique clock using an Arduino Nano, an RTC module, and three formerly 1000VAC analog meters. 

The first order of business for the build was converting the meters into something that could traverse its range with only 5V, accomplished by replacing the stock resistor, diode, and capacitor with a 2.2kohm resistor.

Now controllable via Arduino, new faceplate labels were designed in CorelDraw for a very professional look. Everything was encased in an aluminum stomp box enclosure—actually several as multiple clocks were constructed—and RGB LEDs were also added behind each display. 

Code for the project is available here, and more info can be found in this Imgur set.
