v1.2 Bill of Materials

Description:

In this project a 16 x 8 LED matrix display 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.

To install the code library: 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/examples instead of the Adafruit ones, add ht16k33-master.zip as outlined above for ".zip" files.

And here are three sketches of Arduino code I wrote to test the project:

1) HT16K33_LEDs_Test.ino: Test various patterns on the LED matrices

2) HT16K33_Nums.ino: Test numbers 0 through 9 on each LED matrix

3) HT16K33_BME280.ino: Measure and display the temperature Celsius on the two LED matrices
