Adding external Sensors

External sensors can be connected to the Kniwwelino through the pins available on the outer area. Most Sensors need to be connected to the GND and 3.3V pins of the Kniwwelino, as well as one or more of the outer pins on the lower outer side of the Kniwwelino. Please see the specific sensor section for more details.

You can read the sensor data and use it in your application with the specific block, listed in Sensors:
