Instead of measuring light, we measure the ambient voltage field on pin A5 and use it to detect if someone is too close to our Arduino. A5 is used as a “floating input”, but unfortunately it is very ...

Likely applications are button designs and proximity sensing. The kit’s board also includes a proximity loop which can detect the presence of a finger or hand up to 30cm away. The CapSense MBR3 ...
