/** mDot AnalogIn Example Program
 *
 * This program demonstrates how to read an anglog pin using the
 * MultiTech mDot and MultiTech UDK2 hardware. The only
 * additional hardware required is an analog voltage source like
 * a potentiometer.
 *
 *
 * This program reads the analog input connected to pin PB_1 (UDK2
 * pin A0) and prints the result.
 * And reads temperature/humidity from a DHT22 sensor and prints
 * the result
