This project demonstrates how to control an 8x8 LED dot matrix display using an Arduino and the LedControl library. The code initializes the matrix, displays a predefined pattern, and refreshes it ...

This module utilizes an Adafruit Bicolor LED Square Pixel Matrix with I2C Backpack and an Adafruit Microphone. It introduces how to download libraries for the LED Backpack and how to use it to display ...

This little project is an Arduino sketch designed for the R4 ver. featured with a 12*8 LED matrix. Bad Apple is alredy set inside, but if you want to change it, you can even generate a video by ...

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 ...

This little guy, while simple in nature, acts as a fully functional (and portable) keypad on the go! It comes with two main programs, and it connects easily to your Arduino. It can be used to: 1 ...

Our project is infact an Arduino with Serially Interfaced MAX7219 Operates an 8X8 LED Matrix to display a heart pattern. The MAX7219 IC is a serial input/output common-cathode display driver that ...
