In my ongoing series about cool sensors Interactive Matter presents the AD7746 capacity sensor: What is a capacity sensor good for? You can of course make a device to identify small capacitance (up to 4pF) but that’s boring. Much more interesting is how it reacts to touching. Read on how to connect it to the [...]
