#I got this library for the display in github, it helps me set up the lcd in circuit python,
#https://github.com/dhalbert/CircuitPython_LCD

# Talk to the LCD at I2C address 0x27.
# Here I had to literally go to every forum to get this thing working, setting up the LCD initially was tought for CircuitPython
#as the documentation kinda was old.
#rows 2, and columns are 16 and connected to pins, and adress is 0x27(scanned to find that)
