I am the Evangelist for the Maker Shed. It seems that there is no limit to my making interests. I'm a tinkerer at heart and have a passion for solving problems and figuring out how things work. When not working for Make I can be found falling off my unicycle, running in adverse weather conditions, skiing down the nearest hill, restoring vintage motorcycles, or working on my car.

We’ve had RGB LCD displays in the Maker Shed for a while now and while they are really cool, they take up a bunch of pins on an Arduino. This new Positive RGB LCD Display Shield fixes that problem by using I2C for communication. Using I2C, what once took 9 pins now takes only 2! Since the shield uses the I2C bus, you can add other I2C sensors to the same pins driving the LCD. It’s a great way to incorporate an LCD into your Arduino projects without the messy wiring! It even includes 5 input buttons for building projects that require a user interface. Very nice!

Features:

  • Dimensions: 2.1″ x 3.2″
  • Comes with a 16×2 RGB backlight LCD, positive display
  • Plug and play with any Arduino ‘classic’ – UNO, duemilanove, diecimilla, etc as well as Arduino Mega R3.
  • Uses only the I2C pins – Analog 4 & 5 on classic Arduinos, Digital 20 and 21 on Arduino Mega R3
  • Note: The shield comes as a kit and requires soldering!
