The Arduino MFS has an integrated 4x7 display unit and we can use this to write 4 digit numbers as well as 4 letter words. However, not all alphabetical characters can be visualised due to the format of the 7-segment display.
Installing the MFS Library
The Multi Functional Shield has its own custom library which allows us to use functions when programming. These functions allow us to program and use the sensors and modules on the shield.
Using the following link you can download the .zip library file:
http://files.cohesivecomputing.co.uk/MultiFuncShield-Library.zip
Once, the file has been installed to the PC, we must add this to the IDE. To add a third party library to the Arduino IDE, got to Sketch > Include Library > Add .ZIP Library > Select the file. To install libraries which are supported by Arduino.cc, you can search for them in the library manager. Tools > Manage Libraries.
