Another arduino-controlled art project. This is one is a clock that keeps time by moving the needles on three separate analog voltage meters - one each for hours, minutes, and seconds. In order to get the dials calibrated accurately, I ended up using my Silhouette Cameo cutting machine to etch sheets of anodized aluminum for new face plates for the meters. Then, to add a touch of modernity, I also included a temperature and humidity sensor that displays output on an miniature OLED screen.
