INTRODUCTION

The ADS1115 are precision analog-to-digital converters (ADCs) with 16 bits of resolution offered in an ultra-small, an MSOP-10 package.

Data are transferred via an I2C-compatible serial interface, four I2C slave addresses can be selected, it operate from a single power supply at 3.3V.

It can be used to detect analog signal and convert it to digital signal.

You can attach a joy stick or other analog sensor such as NTC,temperature, dust sensor and so on.
