Detailed Description

This is part of Adafruit's seesaw driver for the Arduino platform. It is designed specifically to work with the Adafruit products that use seesaw technology.

These chips use I2C to communicate, 2 pins (SCL+SDA) are required to interface with the board.

Adafruit invests time and resources providing this open source code, please support Adafruit and open-source hardware by purchasing products from Adafruit!
