The common 16×2 Display usually used with different projects can also be used with Raspberry Pi projects.
we’ll discuss various commands we use with the Python Module to make 16×2 display work via the I2C port on Raspberry Pi. So, let’s start today’s discussion. so , you can python too from this pyhton tutorial.
I2C 16×2 LCD
You’ll have use this LCD module either wither Arduino and NodeMCU Boards, might also with others. But to interface this with Raspberry Pi requires Python modules and code.
So, in order to make the display work like in Arduino Boards, we have to define certain modules.
This LCD has 13 pins out of which 7 pins are used for making communication with the microcontroller. But as this can reduce the availability of the pins on Raspberry Pi, ironically.
Or you can say that it can be a bit complicated in python to code the 7-pin communication to make LCD work.
So to ease this process,
we use an I2C module for the 16×2 LCD which uses the I2C protocol. We can use Raspberry Pi I2C Port to make communicate with LCD and to make it work.
Make sure to power the module with 5V power pins as in some cases the LCD won’t work or may malfunction sometimes.
Also, the Address of the Module may differ, so make sure to check the address of the module.
Use sudo i2cdetect -y 1 command in the terminal to check the address of the display. Make sure to change the code in the Library below.
