What is 8 * 8 LED matrix?
8×8 matrix consists of 64 dots or pixels. There is a LED for each pixel and these LEDs are connected to total of 16 pins. Generally, there are two types of dot matrix – common cathode and common anode. They look almost the same in appearance.
How much LED will have 8×8 LED matrix?
How to Use 8×8 LED MATRIX MODULES. Using LED MATRIX is easy all you need to power the appropriate segment to turn it on. These 64 LEDs in the MATRIX will be tuned ON by appropriately powering the 16 output pins.
How do you make an 8×8 LED matrix?
How To Make An 8×8 LED Matrix
- You’ll need the following parts: a prototyping board, (2) 8 pin headers, (8) 200 ohm resistors and (64) red LED bulbs.
- Arrange the LEDs in the board according to the design you’ve chosen: either common row anode or common row cathode.

What are applications of 8×8 LED matrix display?
It is used to interface microprocessors and microcontrollers with 64 individual LEDs (8 x 8 LED matrix for example has 64 LEDs), seven segment LED displays up to 8 digits or bar graph displays.
How do you control LED matrix?
To control an individual LED, you set its column LOW and its row HIGH. To control multiple LEDs in a row, you set the row HIGH, then take the column high, then set the columns LOW or HIGH as appropriate; a LOW column will turn the corresponding LED ON, and a HIGH column will turn it off.
What is the meaning of LED matrix?
A LED matrix or LED display is a large, low-resolution form of dot-matrix display, useful both for industrial and commercial information displays as well as for hobbyist human–machine interfaces. It consists of a 2-D diode matrix with their cathodes joined in rows and their anodes joined in columns (or vice versa).
What is MAX7219?
MAX7219 is a common-cathode display driver IC with serial inputs and output pins. … In addition to that, it has a four-wire serial interface that can be easily connected to all microprocessors. It can drive 64 individual LEDs connected at its output pins using only 4 wires by using Arduino.
What is a MAX7219 module?
Overview. This module is based on the MAX7219 chip which is a compact, serial input common-cathode driver that interfaces microcontrollers to LED matrices. All common microcontrollers can be connected to this module by using a 4-wire serial interface. Each output can be addressed without refreshing the entire display.
How do dot matrix displays work?
A dot matrix display is an array of light emitting diodes (LEDs) arranged in a 7 X 7 matrix that is used to display a programmed data/information. The main purpose of electronic circuits is to process electrical signals whose amplitudes or vibrations with time contain useful information.
