You will need the Adafruit I2C 16x2 RGB LCD Pi Plate (which also includes five keypad buttons), shown in the following photo:

The Adafruit I2C 16x2 RGB LCD Pi Plate directly connects to the GPIO connector of Raspberry Pi.
As before, we can use the PCF8591 ADC module or use the data_local.py module from the previous section (use data_adc or data_local in the import section of the script). The data_adc.py and data_local.py files should be in the same directory as the new script.
The LCD Pi Plate only requires four pins (SDA, SCL, GND, and 5V); it connects over the whole GPIO header. If we want to use it with other devices, such as the PCF8591 ADC module, then something similar to a TriBorg from PiBorg (which splits the GPIO port into three) can be used to add ports.
