Constructor
| pin | the analog input pin to read samples from |
| periodMs | the number of milliseconds between samples. If update() is called before periodMs has passed since the last update(), no sample will be taken. |
| samples | the number of samples to keep in the ring buffer used to calculate average(), minimum() and maximum(). |
Note: this class dynamically allocated memory for the ring buffer.
