Thermometers are wonderful things, preventing us from burning our fingers or enabling us to decide whether to wear a t-shirt or a pullover. They are used in medicine too, to take temperature readings. However, it often takes an unnecessarily long time to think about what this reading in °C tells us. It would be much better if, at a glance, we could see whether something is hot or cold. After all, we intuitively associate red with hot, and blue with cold. This is used, for example, in modern LED taps. In this case the chosen method is that of an RGB-LED. This can light up red, or blue, and much more besides. In this workshop we can learn how any other coloured light can be mixed from the three primary colours, without getting our hands dirty, and using a single LED. And you can also learn to use an electronic sensor to register the temperature, so you can recreate the electronics to be found in your tap. Your own program is then used to control the mixing of light, irrespective of the actual readings.
