6+
This example for the Arduino Primo Core shows how to use
7+
CoreSensors library.
8+
The example is to show how to detect the double tap
9+
event with the Primo Core. Trying to double tap the
10+
Primo Core, when the event is triggered, the USER LED
11+
will blink twice.
12+
You can check data using serial or BLE *nRF Toolbox*
13+
uart application. When a device with NFC is near to the
14+
Primo Core with NFC antenna, it will try to open the
15+
Nordic's *nRF Toolbox* or look for the app in the store.
16+
17+
This example code is in the public domain.
