Thank you a lot, you made my day ! I am very happy to see the Hello message on my tiny display, this is the first time that my Raspberry gets out of its silicon ;-D Your explanations are clear, precise and concise. Perfect.
Recently I bought a kit(it includes programs) and do that, but the program didn't work correctly. After watching your video, I tried to do this and characters could be output. thank you very much!
Thank you for your video. When I try to download the lcd package, it keeps retrying but in the end it doesn't download. I have i2c enabled. What should I do if I want to use the rip_lcd library?
You will run into this with the latest Raspberry Pi OS version. Read and follow the details provided as pip3 error message, but the easiest workaround may simply be: sudo pip3 install rpi_lcd --break-system-packages
I'm concerned that SDA and SCL can only handle 3,3V signal but the LCD operation is 5V, so it will return the signal back with 5V. Thus, it may damage your raspberry Pi.
In this scenario Raspberry Pi is the controller and it operates the bus at 3.3V. The display is only a receiver and it does not return any signal to the Pi. The setup works because this particular LCD happens to be compatible with a 3.3V control signal.
Great video! I'm going to use this guide to help make a program which shows me when the next bus to work is coming. So I'll never miss the bus again!
Very good video. To the point and a great pace, easy to follow. You should have more views!

Thank you so much, your tutorial helped me get my lcd working

It works perfectly! :D Thank you!

Make sure there are no typos in your command. It may also be a temporary network issue, which could be fixed by a reboot.
When I start the program it says:
from rpi_lcd import LCD()
^
SyntaxError: invalid syntax
Does anyone know why 😢😢
Take out the parentheses
pip3 command doesnt seem to work anymore to install rpi_lcd

My rasp did not detect the address of the LCD. How can I fix this? Thank you for your tutorial.
Check the SDA/SDC connections. Make sure they are connected as I show or not crossed or replace them. Make sure both 5V and GND are connected.
The display is not showing up in i2cdetect -y 1 for some reason

Would this work on a 20 x 4 display?
It all depends on the protocol used by the display - try it if yours uses I2C.
hello ! how can I choose the column and the line ? thanks for your exemple
The library I use allows selecting the line. You can move your text left/right by padding it with spaces.
But how mai i be able tp change the font size?
Not possible with this display. What you want is an OLED display, but the programming model will be different.
