v1.1 Bill of Materials

 

Description:

In this project a 16 x 8 LED matrix displays is  mounted on an Arduino UNO R3 shield.

 

Code:

Adafruit libraries and Arduino code are used to exercise the matrix. You can download the zip file from github.

In the Arduino IDE interface under Sketch|Include Library|Add .zip Library|Documents|Arduino|libraries, select Adafruit_LED_Backpack_Library

Close and reopen the Arduino IDE.

Under File|Examples|Examples from Custom Libraries|Adafruit LED Backpack Library, select matrix16x8.ino

 

If you decide to use the HT16K33 drivers and examples instead of the Adafruit ones, add ht16k33-master.zip as oultined above for ".zip" files.

Here you can find Arduino code to test the project.

 

Next Step:

An RTC (battery-backed real-time clock) from Adafruit could be installed onto the back of the shield and tested.

If you read through the Adafruit matrix library document it should give you some ideas on how to create and scroll a message, etc.
