You can get a long way just using the matrix library, but there is another library, ArduinoGraphics, that has additional functions that make the LED matrix really useful. However, at the time of ...
Most of us have an 8x8 LED matrix from one of our Arduino kits. What can we do with them? This module investigates how to use these interesting devices. Along the way, we describe a fun electronics ...
The 8x13 blue LED matrix is also an example of using PWM to implement gray-level images. The LEDs are connected in a row/column layout in the form of a tree – the first row has one LED pair, the ...
