+  HTS221 - Temperature Alert
+  This example reads data from the on-board HTS221 sensor of the
+  Nano 33 BLE Sense. If the temperature increases above a certain limit, it turns the buzzer on.
+  The circuit:
+  - Arduino Nano 33 BLE Sense
+  - Active buzzer module connected to pin 9 and GND
+
+  written by K.Abhijeet
+  This example code is in the public domain
