The Gnomon is the oldest object used by man to measure time, manipulated for observations, ancient astronomers could determine time measurement patterns such as solstices and equinoxes. In this perspective, this article aims to show the implementation and construction of an electronic Gnomon using Arduino microcontroller and Light Dependent Resistors (LDR) in order to make the sun's direction available via the internet and store its data for future analysis and pattern comparisons.
