Full colour 7-segment digits: more than just numbers
Take a 7-segment digit and make the colour of each segment freely programmable. A bright idea, but why the hell didn't anyone think of it before? Seven segment digits were patented as early as 1903. Only now we can freely program the colour of each segment individually and let it change instantly according to the parameters of our choice. The 4 RGB-displays used in this RGB clock are available in the Elektor Store. The software uses the NeoPixel Arduino library.
