The descriptions are fine, but the visual depictions could be refined to be more concise. The physical LED does not have a bend in it, so when assuming which side goes into the power on the breadboard, because of the pictured LED example, we tend to assume that the "bent end" on the picture is the short leg and should be placed in the power slot. However, its figure examples are misleading and confusing at times. I am not a programmer and the manual is VERY VERY concise with its descriptions. When in fact, it should be the other "non-bent" side inside the power. This "bent leg" on the LED is usually placed in the power slot in the breadboard in most projects. In the LED drawn examples, there is a "bend" that signifies a shorter leg on the LED picture. The confusion is in the picture of the LED. You can download the Max7219 drive library LedControl,zip or program the Arduino/Crowduino with the following Example code.Within the Arduino projects book, there are many times that you are required to place the LED with the long leg (Anode_) to the power and the short leg (Cathode_) to the ground. Connect Arduino GND to GND of 8x8 LED MatrixĪttention:8*8LED Matrix must be common-grounded with Arduino module.Ģ.Check the corresponding interfaces are properly connected.ģ.You'd better powering up the Arduino/Crowduino with AC adapter.Ĥ.Observation:The LED matrix should circularly display the digits 0 to 9 on LED screen first, then the characters A to Z, as shown in the above figure.Connect Arduino 5V to VCC of 8x8 LED Matrix.Be aware that this is a kit, so it comes as a bare PCB and a bag of parts. Connect Arduino pin10 to CLK of 8x8 LED Matrix The shield includes a reset switch and an LED, and it's also a stackable shield.Connect Arduino pin9 to CS of 8x8 LED Matrix.Connect Arduino pin8 to DIN on 8x8 LED Matrix.Use independent power supply for the 8x8 LED Matrix Shield, and the supply voltage is 5V/2A. Connect Arduino pin 10 to CLK on the LED Matrix.Connect Arduino pin 9 to CS on the LED Matrix.Connect Arduino pin 8 to DIN on the LED Matrix.The 8x8 LED Matrix must be common-grounded with the Arduino module.Please follow the following instructions to connect hardwares. The schematics of the LED matrix is attached below. you need to change the direction then assemble it. Please pay attention that if it doesn't show as you wanted. Please download this step by step Assembly tutorials and then follow it to solder it. This is a great beginner kit, easy to make even if you are have never soldered before. Typical Temperature: 25 ℃ Assembly Instruction The kit includes the following components:Īfter assembling, The Led matrix module will look as: This product comes in the form of a kit or module. The persistence of vision for humans is about 0.1s, so as long as we can serially display all 8 rows/columns within 0.1s, we’ll see a complete character or pattern. The serial-driven LED matrix actually dynamically displays the LEDs, i.e., displays the LEDs row-by-row or column-by-column. Mini Nano Leaf Nanoleaf is a brand of smart lighting in the form of color-changing triangular or hexagonal panels. We usually drive it in the serial manner in order to save interface. The LED matrix can be driven in two ways: parallel or serial. If the LED matrix is not driven by any peripherals, it’ll waste the interface of devices, and the LED brightness will be impaired due to insufficient power, so that we cannot get ideal display effect. The 8x8 LED Matrix is easy to use and compatible with Arduino, and its LED brightness adjustment can be implemented in software.Ĩx8 LED Matrix kit has many applications in real life, such as various types of electronic display panels. It only needs three data lines and two power lines. This product is a serially driven 8x8 LED Matrix kit powered by MAX7219.
