Product Details
To control an 8x8 dot matrix display, you use a driver IC like the MAX7219 or similar, which simplifies the process by providing serial communication and multiplexing capabilities. However, if you choose to drive the display without a dedicated driver, you will need to control each LED individually using a microcontroller or other control circuitry. This involves setting the appropriate voltage levels and timing sequences to turn on/off specific LEDs to create the desired patterns or characters on the display.
