The YourDuino RoboRED (UNO Compatible) has a 4-pin connector that works well for this type display. When they are connected to a controller, multiple IOs will be occupied of the . All the prices are low due to China purchase. One i2c module (1€-2€) LINK eBay 3. Mise en oeuvre de la carte I2C vers LCD.

Caractéristiques du produit. Using it can reduce the difficulty of make, so that makers can focus on the core of the work. The library allows to control I2C displays with functions extremely similar to LiquidCrystal . I2C bus converter and related libraries, you can easily use this module with just wires. It is able to display white characters on lines on blue background. Find this and other hardware projects on Hackster.
As mentioned in the page you linke jumper together one of the address jumpers. For example, above Aare two pads. Solder a wire across them ( vertically – between the two pads above A0). I am guessing the address is pulled high by a resistor, so that will probably make the new address 0x3E, but you . Finally you will see how to program it with a simple example showing how . I like quick and easy implementation and I like having pins left over for other things.
The I2C interface itself is actually a small daughter board that has been soldered onto a readily available LCD. The buttons (if used) are wired with a normally open (NO) switch to ground. Pressing the button will contact the ground signal) Jon the PCB has an extra ground and pins for buttons to 5.
