This new shield makes it easy to use a 16x2 Character RGB LCD. The RGB LCDs we stock are really cool but unfortunately, these LCDs do require quite a few digital pins; 6 to
control the LCD and then another 3 to control the RGB backlight for a
total of 9 pins! That's half of the pins available on a classic Arduino!
This shield addresses this problem head on. It lets you control a 16x2 Character LCD, up to 3 backlight pins AND 5 keypad pins using only the two I2C pins on the Arduino!
The best part is you don't really lose those two pins either, since you
can stick i2c-based sensors, RTCs, etc and have them share the I2C bus.
This is a super slick way to add a display without all the wiring
hassle.
This shield is perfect for when you want to build a stand-alone project
with its own user interface. The 4 directional buttons plus select
button allows basic control without having to attach a bulky computer.
The shield is designed for 'classic' Arduinos such as the Uno,
Duemilanove, Diecimilla, etc. It will also work perfectly with Arduino
Mega R3's. Earlier Mega's have the I2C pins in a different location and
will require you to solder two wires from the I2C pins on the shield and
plug them into the different I2C locations at Digital 20 & 21.
This product comes as a kit! Included is a high quality, USA-made PCB and all the components (buttons, header etc). This product comes with a 16x2 RGB positive LCD. Assembly is easy, even if you've never soldered before and the kit can be completed in 30 minutes. Check the product tutorial page for assembly instructions before purchasing
