+* Example sketch for the ADS1115_WE library
+*
+* This sketch shows how to use two ADS1115 modules. In order to set the address,
+* connect the address pin to:
+*
+* GND -> 0x48 (or leave unconnected)
+* VCC -> 0x49
+* SDA -> 0x4A
+* SCL -> 0x4B
+*
+* When you have understood how it works you can easily add two additional ADS1115.
+* Of course there is potential to shorten the code, e.g. by setting up the ADCs
+* as array.
+*
+* If you need up to eight ADS1115 modules you can use an ESP32 with its two I2C
+* interfaces:
+* https://wolles-elektronikkiste.de/en/how-to-use-the-i2c-interfaces-of-the-esp32
+*
+* If you need up to 32 ADS1115 modules you can use a multiplexer like the TSCA9548A:
+* https://wolles-elektronikkiste.de/en/tca9548a-i2c-multiplexer
+*
+* Or you combine both and control up to 64 ADS1115 modules.
+*
+* Further information about the ADS1115 can be found on:
+* https://wolles-elektronikkiste.de/ads1115 (German)
