+Example: Control ADS1115 connected to PCA9685 driver onboard of Navio shield for Rapspberry Pi.
+
+Connect a wire to P1 and the ADC will measure its voltage and display it.
+Be careful, do not connect high-voltage circuits, for acceptable range check the datasheet for ADS1115.
+
+To run this example navigate to the directory containing it and run following commands:
+make
+./ADC
