If you are a beginner this is probably the best starting point for you. It is always nice and interesting to make something useful. The project works with a motion sensor which reports its’ own state through a simple GPIO pin. Then we have the Relay click board which can also be controlled with simple GPIO pins […]
Cap-sense or capacitive sensing is a measurement of changes in capacitance. The technology is based on capacitive coupling and can be used to detect approaching or touching the sensor by any kind of conductive object or object that has a dielectric different from surrounding air.
