 ### Step 2: Sampling the sensor

+Define the callback that will be passed to the `SensorSampler`, along with the sensor.  
+Inside the callback you can get the sampled data from the sensor and perform operations on it.
+```cpp
 void testCallback() {
-    // get the sampled data and 
-    // perform whatever action you want
     float data = sensor->getData();
     printf("Test data : %f \n", data);
 }
+```
+You use use `std::bind()` in order to bind your callback to an `std::function<void()>>` object.  
+Select the required frequency for the sampling and add the sensor and the callback to the `SensorManager`.  
   
+You can now start the `SensorManager`.
+```cpp
 int main() {
 
     uint32_t frequency = 10;  // 10 Hz
