Design, development and implementation of electronics and embedded software to drive capacitive distance sensors and high-power LEDs.
In this simple "matching game" we have used capacitive sensors for the switches. Such switches can be invisibly hidden below a panel: they react on a hand or finger moving within a controllable distance to the switch. Additionally, the sensor of the switch is just a film of conductive material, which can be cut to match neatly the object printed on the top side of the panel.
