Information Display with an LCD Digital Display

The MakerBit board has 4 pins at the upper-right corner of the board that support the "I2C" protocol. and that can be used to connect to LCD text displays, certain sensors, and neopixel strips.

When the LCD display is connected and this MakerBit program is used, the display will indicate which touch sensor is being touched, and also display the analog values of A0 and A1.

To connect the LCD, plug the 4-socket connector cable into the I2C connector at the upper-right of the MakerBit board, with the black wires towards the top of the board.


Connect the individual sockets to the 4 pins on the back side of the LCD display so that the connections and wire colors are:

GND:  Black


VCC:  Red


SDA:  White


SCL:  Yellow

When the display turns on, you can adjust the blue trimmer on the back of the LCD display with a small screwdriver to get the optimum contrast and best display.



When touch sensors are touched, the touch sensor pin number will be displayed.



Audio Playback Display


If you have the Audio Narration (mp3 player) module attached, then the LCD display will display the touch sensor that is touched, and the folder and track number that is being played.

Analog & Touch Display


If you have analog sensors attached to A0 and A1, and not the audio narration module attached, then the LCD display will display the touch sensor that is last touched, and the real-time values of A0 and A1 (such as photocells).


The audio narration module and the analog sensors of A0 and/or A1 cannot be used at the same time. If you do wish to use the audio narration module with some sort of analog sensing, use A4 for the photocell or other analog sensor.
