If you’re using an Pro Mini-compatible the pins are A4 and A5 for data and clock, which are parallel to the main pins, as shown below: If you’re using an Arduino Mega the pins are D20 and D21 for data and clock: On Arduino Uno or compatible boards, these pins are A4 and A5 for data and clock: Moving on – first you will need to identify which pins on your Arduino or compatible boards are used for the I2C bus – these will be knows as SDA (or data) and SCL (or clock). The library to use for this ‘mjkdz’-module is “ LiquidCrystal_I2C.h” and can be found here: Other I2C-modules are available, like the ‘mjkds’-module: #WIRE H LIBRARY ARDUINO DOWNLOAD PRO#
