Connect GND Black Wire to common power/data ground
Connect the SCL Green Wire pin to the I2C clock SCL pin on your Arduino. On
an UNO & '328 based Arduino, this is also known as A5, on a Mega it is also
known as digital 21 and on a Leonardo/Micro, digital 3
Connect the SDA White Wire pin to the I2C data SDA pin on your Arduino. On an
UNO & '328 based Arduino, this is also known as A4, on a Mega it is also known
as digital 20 and on a Leonardo/Micro, digital 2
Install Adafruit_seesaw library
