In stock
The 16 Pin 8×8 Dot Matrix LED Display Red Digital Tube is a small display module that allows you to show letters, numbers, and simple symbols using red LEDs. Here’s a breakdown of its key features:
- Size: The display itself is made up of an 8×8 grid of red LEDs (typically 3mm each). The overall size of the module will vary depending on the manufacturer.
- Color: Red LEDs
- Resolution: 8×8 pixels (each LED represents a pixel)
- Number of Pins: 16 pins for controlling the LEDs and the display.
- Functionality: By turning individual LEDs on or off in specific patterns, you can create letters, numbers, and simple symbols on the display.
Control Mechanism:
There are two common control types for these displays:
- Common Cathode: In this type, all the LED cathodes (negative terminals) are connected together, and each LED anode (positive terminal) has a separate pin for control.
- Common Anode: Conversely, all LED anodes are connected together, and each cathode has a separate pin for control.
The specific control method (common cathode or common anode) will depend on the model and will be crucial information for connecting it to your microcontroller.
Applications:
- Simple displays: Showing numbers, letters, or basic symbols for time, temperature, or status indicators.
- Custom displays: With creative coding, you can create more complex patterns or animations.
- Educational projects: Learning about LED control and character displays using microcontrollers like Arduino or Raspberry Pi.
Using the Display:
To use this display, you’ll typically need:
- Microcontroller: A microcontroller like Arduino or Raspberry Pi to control the LED states and create the patterns you want to display.
- Coding: Basic programming knowledge to write code that sends signals to the display pins to turn LEDs on and off in the desired pattern.
- Connecting wires: To connect the display’s pins to your microcontroller.
- Power supply: To provide the appropriate voltage (usually 5V) to the display.
While these displays are relatively simple, they can be a fun way to add a visual element to your projects. For specific wiring diagrams and coding examples, you’ll need to consult the datasheet or product information provided by the manufacturer you purchase from.
