Here's how addressing works on the I2C LCD adapter: The address of this particular adapter will always be a 2-digit hexadecimal number in the range of 20 to 27 (0x20 to 0x27). There are three address jumper pads on the adapter PC board labeled A0, A1 and A2. The address lines have pull-ups, so an open jumper sets the address line to a 1, while a closed jumper sets it to 0. The jumpers determine the least significant digit of the address, while the most significant digit is always 2. Therefore, the least significant digit will correspond to this truth table, where a 1 signifies no jumper, a 0 signifies a jumper in place: A2 A1 A0 I2C addr 0 0 0 0x20 0 0 1 0x21 0 1 0 0x22 0 1 1 0x23 1 0 0 0x24 1 0 1 0x25 1 1 0 0x26 1 1 1 0x27 So, installing no jumpers (the default) results in an address of 0x27 on these adapters.

Finding sketches and methods for pc hardware monitoring are hard to come by for i2c LCD's. I tried to get one working with LCD Smartie but all I get is random numbers. If you know of any methods of monitoring pc motherboards, i.e. cpu speed, available ram, etc please let me know.

HI I am using Arduino IDE and had a problem with the display only printing 1 character. If the library you used updated? .

Thanks a lot, great video :) Btw, do i need to solder all the A0 A1 A2 pins in the i2c to get several adresses, for using only 2 lcd screens and display different text ? Thx in advance and thx again for this great video !

Hi there! I followed exactly along and my ide shows an error with the lcd.begin() comand. It says there is no matching function to call in liquid crystal....Please help!

You need to download I2C liquid crystal.h library from browser on GitHub or Arduino libraries website

I don't know if it was the same problem i had - but the solution was the potmeter setting. A slight turn and the characters turned nicely up on the screen.
