+* Example sketch for the ADS1115_WE library

+*

+* This sketch shows how to use the ADS1115 module with the TinyWireM library:

+* https://github.com/adafruit/TinyWireM

+* This allows you to run the ADS1115_WE library on an ATtiny85, for example.

+* 

+* For this specific sketch you also need library Tiny4KOLED to display the 

+* measured values on a SSD1306 OLED display:

+* https://github.com/datacute/Tiny4kOLED

+*  

+* Further information can be found on:

+* https://wolles-elektronikkiste.de/ads1115 (German)

+* https://wolles-elektronikkiste.de/en/ads1115-a-d-converter-with-amplifier (English)
