8x8 bi-color LED Matrix

This version of the LED backpack is designed for these bright and colorful square=pixeled 8x8 matrices. They have 64 red and 64 green LEDs inside, for a total of 128 LEDs controlled as a 8x16 matrix. This backpack solves the annoyance of using 24 pins or a bunch of chips by having an I2C constant-current matrix controller sit neatly on the back of the PCB. The controller chip takes care of everything, drawing all 128 LEDs in the background. All you have to do is write data to it using the 2-pin I2C interface. There are three address select pins so you can select one of 8 addresses to control up to 8 of these on a single 2-pin I2C bus (as well as whatever other I2C chips or sensors you like). The driver chip can 'dim' the entire display from 1/16 brightness up to full brightness in 1/16th steps. It cannot dim individual LEDs, only the entire display at once.

Arduino MIDI Mouse Controller

“Turn an old “roller ball” mouse into a MIDI controller that can unlock new ways of making digital music. Reimagining MIDI devices based on old electronics I hate throwing away old electronics that still work but are no longer supported …

LED Matrix Metronome

“Combine Arduino, an 8*8 bicolour LED matrix and a piezo buzzer to make a cool visual metronome. I’m an Arduino fan and a musician. Practicing with a metronome is a great way to improve your musicianship, but most …

Led Matrix Touch Control

“This time Ill share how to integrate touch control into the bi-colors led matrix 16x32. It can be used to control indoor devices via led panel or carry out some interactive effects by touch action. It may sound strange but …

8X8 matrix LED Snake game (HTML5 web socket)

“I added a web page to PHPoC Shield for Arduino(P4S-347/348) to control a snake on the 8X8 Matrix LED. If a user presses one of direction buttons, the direction value is sent to Arduino through HTML5 Web …

Arduino Matrix Clock

“So, a little introduction as to why I made this project. For school we needed to make an interactive arduino project and because I’m not the best programmer in the world so I’ve chosen to make an interactive …
