LEDs offers a combination of flexibility and efficiency unmatched by conventional forms of lighting, and are being adopted in architectural- and stage-lighting applications because they emit highly ...
The circuit is driven by a MAX7219 IC that is being controlled through an Arduino microcontroller board, to create an 8X8 LED matrix. The connection of the LED matrix and the IC was done on a ...
Microcontroller port pins can typically be driven either high or low, or else be put into an "input" or high-impedance state. This circuit uses the three states to drive two separate LEDs with one ...
