Please visit our second website Ptechnicians. It has 54 digital input/output pins (of which 15 can be used as PWM outputs), 16 analog inputs, 4 UARTs (hardware serial ports), a 16 MHz crystal oscillator, a USB connection, a power jack, an ICSP header, and a reset button. We provide free LCD/LED TV Firmware files, and all other Schematic diagrams, Datasheets Service Manuals, Bin/Flash files, and more for free. The Arduino Mega 2560 is a microcontroller board based on the ATmega2560. You are on this is about Electronics like LCD/LED TVs, Laptop/Computer, Satellite receiver, and other electronics.

After all, wouldn't it be awesome if you could control a matrix without tons of wiring? That's where these lovely LED matrix backpacks come in.
That's a lot of pins, and there are driver chips like the MAX7219 that can control a matrix for you, but there's a lot of wiring to set up and they take up a ton of space.
Matrices like these are 'multiplexed' - to control 64 LEDs you need 16 pins. A fun way to make a small display is to use an 8x8 matrix or a 4-digit 7-segment display.
