Arduino Advent Calendar Day 16 - Touch Sensor!
It's time to get touchy feely with the Capacitive Touch Sensor.
As it's name suggests, a touch sensor is a type of sensor that captures and records physical touch or loving embrace on an object.
Capacitive Touch sensors work with anything that holds an electrical charge – including human skin. Our skin is actually quite a good dielectric material (a relatively poor conductor of electricity, but an efficient supporter of electrostatic fields) because our bodies are mostly dirty bags of water.
Yup, enough talking about it let's go and build up the circuit over at guides.littlebird.com.au !
