Actually, LCD I2C is composed of a normal LCD, an I2C module and a potentiometer. Pinout LCD I2C uses I2C interface, so it has 4 pins: GND pin: needs to be connected to GND (0V). VCC pin: the power supply for the LCD, needs to be connected to VCC (5V). SDA pin: I2C data ...

Drill the crosses first with 1/8" holes and then widen them with larger 3/8" holes. Peel away this template as well, and the case should be ready. Step 6: Wire the Pots Attach three 6" wires to each of the potentiometers.
