Project Description:
********************
in this tutorial, you will learn how to use the ADS1015 12-bit i2c supported Analog to digital converter with the Nodemcu ESP8266 to increase the number of Analog pins so that multiple analog sensors can be interfaced with the Nodemcu ESP8266. For demonstration purposes, I have connected 3 potentiometers which I am using as the sensors which of course you can replace with other analog sensors. I started with a very basic program and displayed the values of all the three potentiometers on the Serial monitor.

I further modified the code and this time I displayed the values of all the three analog sensors on the I2C supported Oled Display Module. The ADS1015 and the Oled display module both supports I2C communication, which means using only two pins D1 and D2 I can communicate with both the modules.
