    A must have for LCDs. I can't stand wiring up LCDs, so its much easier to solder one of these on the back of a 1602 display. Haven't used it yet with a 2004. (Posted on 27/05/2017)

    I connected the backpack to my 1602 LCD.

    I downloaded and imported the LiquidCrystal I2C Library from the link in the description and tried to upload the included Hello World sketch.

    I could upload the sketch ok but it wouldn't display any text on the LCD.

    I noticed that the I2C address was 0x3f. I changed it to 0x27 and uploaded the sketch again. This time it worked perfectly.
