Since these modules use the MAX7219 LED driver chip, we will be able to turn on and off the 64 LEDs of each modules, using only 3 pins on our Arduino. Da diese Version noch auf simpler Pappe verlötet ist, folgt aber noch eine bessere Version, die sich dann ebenfalls über einen Editor auf dem PC noch mit Inhalt füllen lassen soll. I - Items To work with this project, we need some simple items, take a look: Any Arduino board 16x16 LED Matrix Push button 1K resistor Connect your 16x16 LED Matrix with your Arduino…. 8x8 LED Matrix MAX7219 Controller Operating Voltage: 4. what you will learn in this post is how to connect the i2c dot matrix on arduino pins, how to put characters on it. In this tutorial we make a SCROLLING DOT MATRIX device with Bluetooth connection and a real time clock to show time, date, temperature and day of the week. The led matrix has 2 IDC connectors (DATA_IN, DATA_OUT) on the back, you can cascade multiple panels and make a huge screen together.
