- This is Key Display For AVR Arduino New 8-Bit Digital LED Tube 8-Bit TM1638 Module
- With TM1638 Chip, this module gathers more than three common SCM peripheral circuits.
- The advantage is only three IO ports will be occupied when it drives.
- SCM doesn't need to work for scanning display and key scanning.
- It only needs to read the relevant register to send display data or test button so it saves MCU resources effectively.
Key Display For AVR Arduino
The TM1638 Button Digital LED Display Module is used in chip TM1638, a collection of these three common MCU peripheral circuit, the biggest feature just takes three microcontroller like Arduino IO port to drive, do not need to scan display and key scanning microcontroller intervention, only need to read the relevant register send display data or test button, save MCU resources.
This module gathers more than three common scm peripheral circuits. The advantage is only three io ports will be occupied when it drives. Scm doesn't need to work for scanning display and key scanning. It only need to read the relevant register to send display data or test button so it save MCU resources effectively. Keys are sensitive and display effectively.
Features:
- TM1638 digital tube drive chip to drive a common cathode LED digital tube.
- Can be extended to 3 * 8 buttons, led digital tube and can be controlled separately.
- Support 8 brightness control, led digital tube and use the same brightness.
- Support cascading up to 6 of the same module.
- 8 LED, 8-bit digital tube and 8 buttons, common cathode LED digital tube, such as STC microcontroller can be directly connected.
Applications:
- DIY Electronics Projects: Ideal for hobbyists creating custom electronics projects that require a display and user input.
- Arduino and AVR Projects: Frequently used in projects involving Arduino and AVR microcontrollers for displaying numerical data and receiving user input.
- Home Automation Systems: This can be integrated into home automation systems to display status information and receive commands.
- Consumer Electronics: Used in the front panels of devices like DVD players and home theater systems for display and control purposes.
- Educational Tools: Useful in educational settings for teaching students about microcontroller programming and interfacing.
- Prototyping: Handy for prototyping new devices that need a simple interface for testing and development.
